Crash Bandicoot 4 features 43 levels (5 are boss levels and 38 are Normal Levels).
The 38 Normal Levels each have a Platinum Time Trial Relic and N.Sanely Perfect Relic.
There are also 21 Flashback Levels, that are unlocked by collecting the Flashback Tapes in Normal Levels without dying.
The 43 main levels must all be replayed in N.Verted Mode.
Some levels must be replayed in different timelines with other characters. There’s a lot to do and you’ll have to earn every Relic and get 106% game completion for doing everything possible in the game. It’s a skill dependent achievement list.

This guide is being updated with pictures/videos as long as I have the time to do it.

Complete a Bonus Path

Every level playable with Crash and Coco contains a Bonus Path.
A Bonus Path is a circle platform with a large question mark which will take you to a side-scrolling section where you will be able to obtain extra lives if playing in Retro Mode, Wumpa Fruit, and crates that will count to your total crate count for that level.
Simply complete any bonus path to earn this achievement.
You can get this achievement during the first level, Rude Awakening.

Complete all Timelines / Complete any Timeline

Timelines are optional levels unlocked as you progress through the story and play as one of three other characters (Tawna, Dingodile and Cortex) for the first time.
After completing the character's introductory level, you will then be able to play a timeline variant of an already completed level where you will play as one of the three characters for the first half of the level.
The second half of the level will be a more difficult variant of the original level with Crash/Coco.
There are a total of nine Timeline levels throughout the game.
Completing one of the nine will award you with Putting Things In Perspective.

The nine levels are:

• Truck Stopped - Timeline variant of Hit the Road in The Hazardous Wastes Dimension. First half played with Tawna.
  
• Thar He Blows! - Timeline variant of Booty Calls in the Salty Wharf Dimension. First half played with Dingodile.
  
• Potion Commotion - Timeline variant of Give it a Spin in the Tranquility Falls Dimension. First half played with Tawna.
  
• No Dillo Dallying - Timeline variant of Run It Bayou in the Mosquito Marsh Dimension. First half played with Dingodile.
  
• Ship Happens - Timeline variant of Snow Way Out in The 11th Dimension. First half played with Cortex.
  
• Building Bridges - Timeline variant of Bears Repeating in The 11th Dimension. First half played with Tawna.
  
• Rock Blocked - Timeline variant of Dino Dash in the Eggipus Dimension. First half played with Dingodile.
  
• Shipping Error - Timeline variant of Out For Launch in the Bermugula's Orbit Dimension. First half played with Cortex.
  
• Seeing Double - Timeline variant of Cortex Castle in the Cortex Island Dimension. First half played with Cortex.

Completing all nine will award you the achievement.

These trophies are rewarded for performing a certain action or task, sometimes in a specific level.
It is likely that you may have acquired some of these trophies already during your initial playthrough.

By the end, you should have the following trophies:

Play a game of Checkpoint Race

On the Main Menu, select Bandicoot Battle, 2 Players then select Checkpoint Race.
While this is technically a multiplayer mode, it is played using a single controller as an offline multiplayer mode by passing the controller from the first player to the second.
The aim is to see who can get from checkpoint to checkpoint the fastest, with the scores totaled at the end of the level.
The quickest method is to select the first level, Rude Awakening, and intentionally die in between checkpoints as it jumps to the next checkpoint upon doing so.
Complete the level and you are awarded the achievement regardless of who the winner is.

Play a game of Crate Combo

On the Main Menu, select Bandicoot Battle, 2 Players then select Crate Combo.
While this is technically a multiplayer mode, it is played using a single controller as an offline multiplayer mode by passing the controller from the first player to the second.
The aim is to see who can score more points from crates (the crates double in value within a time limit when broken, up to a maximum value of 32 points per crate) between checkpoints.
The scores are then totaled at the end of the level.

Similarly to Fleet of Feet, the quickest method is to select the first level, Rude Awakening, and intentionally die in between checkpoints as it jumps to the next checkpoint upon doing so.
Complete the level and you are awarded the achievement regardless of who the winner is.

Complete a level with Pass N. Play enabled

Similar to Fleet of Feet and Settle the Score, it is played using a single controller as an offline multiplayer mode by passing the controller from the first player to the second upon completing a checkpoint.
Complete any level to unlock the achievement

Complete a level as Coco

After completing the first two levels, you will be taken to the Dimensional Map. Here you can switch to play as Coco instead of Crash.
Complete any level as Coco to unlock the achievement..

Try on a Skin

Skins for both Crash and Coco are unlocked by collecting gems throughout the game.
To equip a skin, press Y/Triangle while on the Dimensional Map and select an unlocked skin to unlock this achievement.

Pull off a Triple Spin

The Triple Spin is unlocked after defeating Cortex in the final boss fight to finish the main story. Simply revisit any level and press X/Square three times (with a slight pause between every press) while running and you will pull off a Triple Spin, awarding you with the achievement.

The Triple Spin looks different to a normal spin (blue in colour) and also gives you a boost in speed, thus coming in handy for Time Trials.

Defeat an enemy with Triple Spin

The Triple Spin is unlocked after defeating Cortex in the final boss fight to finish the main story.
Simply revisit any level and press B/Square three times (with a slight pause between every press) while running and you will pull off a Triple Spin.
Ensure that the third spin (blue in colour) hits an enemy and you will be rewarded with this achievement.

Beat a story level without dying

Complete any level with zero deaths, most easily acquired on the first level of the game, Rude Awakening.

Find the source of the Bumpa Berries

At the beginning of Off-Balance in the Tranquility Falls Dimension, you will see a tree in front of you at the start of the level.
Simply jump and spin the tree branches to make a bunch of Bumpa berries stun you, unlocking this achievement.

Scare the cat hiding from a party

In the level Off Beat in the Mosquito Marsh dimension, spin the dumpster to the right of the second checkpoint.

Aim and fire!

While playing as Dingodile in Thar He Blows! in the Salty Wharf Dimension, you will reach the top of the level and Dingodile will say "You smell good enough to eat. Hehe!" Here you will see two broadside cannons.
Spin the cannons to earn this achievement.

Do some target practice

While playing as Dingodile in his introductory level Home Cookin', you will come across large purple bat signs scattered throughout the level.
There are five of them in total. Destroy them all by sucking up and shooting nearby TNT barrells/crates to get the achievement.

Make music in an unlikely place


In Hit the Road on the Hazardous Wastes Dimension, you will come across three barrels at the beginning of the stage (two to the left, one on the right) and three other barrels to the left of the bonus platform that create a melody when hit.
Hit all six barrels to earn the achievement.

Grabbed a bushel of Bumpa

At the beginning of A Hole in Space in the Bermugula's Orbit Dimension, you must grind on a rail before fighting the Doctors N. Tropy.
On this rail are 18 Bumpa berries that you can collect, with the use of Lani-Loli in the later part of the rail grind. Collect all 18 Bumpa berries to earn this achievment.

Shut N. Brio up / Shut N. Gin up

Near the beginning of A Real Grind in the Hazardous Wastes Dimension, after crossing the first two footbridges, you will come across a megaphone with a picture of N. Gin's face next to it that N. Gin is speaking from.
Spin the megaphone to destroy it and get the achievement.

The same premise for Give it A Spin
After the first Checkpoint of Give it A Spin in the Tranquility Falls Dimension, you will come across a platform with five TNT crates.
On the platform to the right is a beaker filled with green liquid, which N. Brio is seemingly speaking from.
Break the beaker to get the achievement.

Make some noise!

In Draggin' On in the Tranquility Falls Dimension, there are four golden gongs in the first half of the level that you must hit in order to get this achievement.

These are the four golden gongs and where to find them:

• The first is hanging in the doorway above the stack of crates at the beginning of the level.
  
• The second is a little further along the main path, hanging in an archway just before the two dragons.
  
• The third is hanging in the archway above the three TNT crates further down the main path.
  
• The fourth and final one you can see on the main path, hanging on a wall just past the two lions not far from the third gong.

Spend some time surfin' the waves

At the beginning of the first level, Rude Awakening in the N. Sanity Island Dimension, you will see a TV on your left.
Spin the TV three times until it shows the title screen for Crash Bandicoot 4 to receive the achievement.

It is likely that you will have missed a number of clear gems throughout your first playthrough, so you can come back later to clean up your remaining gems.
Begin with collecting the four coloured (Red, Green, Blue, Yellow) gems before moving onto the remaining clear gems.
These four coloured gems unlock gem paths for specific stages which contain crates that must be broken in order to acquire the gem for breaking all crates for that specific level.

Upon completing this stage, you should have the following achievements:

• Sapphire-er Acquirer - Find the hidden Blue Gem
  
• Like a Rhinestone Bandicoot - Earn half of the Clear Gems
  
• King of Bling - Earn ALL of the Clear Gems
  
• Emerald Gemerald - Find the hidden Green Gem
  
• Ruby Red - Find the hidden Red Gem
  
• Topaz Pizazz - Find the hidden Yellow Gem

For the colored gem locations/achievements, check out this guide by Maj0r P1st0l™https://steamproxy.net/sharedfiles/filedetails/?id=2880287435

Earn ALL of the Clear Gems / Earn half of the Clear Gems

There are a total of 228 Clear Gems throughout the game, consisting of 6 Clear Gems per level in each of the 38 levels. The boss levels do not contain any gems.

In every level, the six Clear Gems are earned by:

• Collecting 40% of the Wumpa Fruit in the level
  
• Collecting 60% of the Wumpa Fruit in the level
  
• Collecting 80% of the Wumpa Fruit in the level
  
• Breaking all of the crates in the level
  
• Die 3 times or less
  
• Finding the Hidden Gem in the level

Earning 114/228 Clear Gems will reward you with the Like a Rhinestone Bandicoot achievement.

Flashback Tapes are a new collectible to the franchise introduced in this game which unlock an optional level that can be accessed via the Dimensional Map or through the Level Stats screen on the Dimensional Map.
There are a total of 21 Flashback Tapes scattered throughout the ten dimensions in the game.
To acquire a Flashback Tape, you must play through the level containing the tape with zero deaths, until the tape is found.
Upon collecting the tape, it is okay to die but the level must be completed to keep the tape (i.e. picking up the tape and exiting to the Dimensional Map will not reward you with the tape).

All of the Flashback levels are side-scrolling platforming levels, very reminiscent of the N. Brio/Cortex Bonus levels from the original Crash Bandicoot. There are no lives or death counters in these levels, so take as many attempts as you need to complete them.

Finishing this stage will unlock the following achievements:

• Model Test Subject - Earn any Flashback Relic
  
• Closing the Experiment Log - Earn ALL of the platinum Flashback Relics
  
• A/V Club Founder - Acquire a Flashback Tape

Earn ALL of the platinum Flashback Relics / Earn any Flashback Relic

In order to unlock the optional Flashback levels to collect the Flashback Relics, you must collect the Flashback tapes. To acquire a Flashback Tape, you must play through the level containing the tape with zero deaths, until the tape is found.
Upon collecting the tape, it is okay to die but the level must be completed to keep the tape.

There are 21 Flashback Tapes scattered throughout the ten dimensions in the game.
The levels containing a Flashback Tape are listed below:

• Crash Compactor (The Hazardous Wastes)
  
• Hit the Road (The Hazardous Wastes)
  
• Booty Calls (Salty Wharf)
  
• Jetboard Jetty (Salty Wharf)
  
• Give It a Spin (Tranquility Falls)
  
• Draggin' On (Tranquility Falls)
  
• Off-Balance (Tranquility Falls)
  
• Off Beat (Mosquito Marsh)
  
• Run It Bayou (Mosquito Marsh)
  
• Snow Way Out (The 11th Dimension)
  
• Stay Frosty (The 11th Dimension)
  
• Bears Repeating (The 11th Dimension)
  
• Blast to the Past (Eggipus Dimension)
  
• Dino Dash (Eggipus Dimension)
  
• Out For Launch (Bermugula's Orbit)
  
• Stowing Away (Bermugula's Orbit)
  
• Crash Landed (Bermugula's Orbit)
  
• Food Run (Sn@xx Dimension)
  
• Nitro Processing (Cortex Island)
  
• Toxic Tunnels (Cortex Island)
  
• Cortex Castle (Cortex Island)

Completing any of the Flashback Levels will earn you a Flashback Relic, and the Model Test Subject achievement.

The requirements for the Flashback Relics are as follows:

Sapphire: Complete the flashback level.
Gold: Complete the flashback level, and break 90% of the crates.
Platinum: Complete the flashback level, and break all of the crates.

Collecting the Platinum Flashback Relic will automatically earn you both the Sapphire and Gold Flashback Relics for the level. Collect all 21 Platinum Flashback Relics to earn this achievement.

Acquire a Flashback Tape

Find any of the 21 Flashback Tapes in the game.
You will most likely get this achievement on your first playthrough of Crash Compactor on the Hazardous Wastes Dimension, as the Flashback Tape is right in front of you at the start of the level.
Complete the level to keep the tape and earn this achievement.

After defeating N. Brio, you will unlock the ability to replay levels in N. Verted Mode, which is a mirror mode with a whacky visual (and sometimes gameplay) altering filter.
This is essentially another full playthrough, as you will be tasked in completing every level and defeating all five bosses in N. Verted Mode and collecting six N. Verted gems per level (same requirements as the normal clear gems).

In this stage you can get the following achievements:

• Beat ‘Em Any Which Way - Beat any boss in N. Verted mode
  
• Backwards & Forwards - Complete ALL levels in N. Verted mode
  
• IT’S MESSING WITH MY HEAD, MAN!!! - Beat a level in N. Verted mode
  
• gnilB fo gniK - Earn ALL N. Verted Gems

Complete ALL levels in N. Verted mode / Beat any boss in N. Verted mode / Beat a level in N. Verted mode

After defeating N. Brio in Trouble Brewing in the Tranquility Falls Dimension, you will unlock the N. Verted Mode.
N. Verted Mode will then be available for any level once that level is completed on Normal mode.
In N. Verted Mode, every level will be mirrored and each dimension will have its own visual filter.

While going for this achievement, here are other achievements you will get naturally:

Completing any level in N. Verted Mode will award you with IT’S MESSING WITH MY HEAD, MAN!!!.
Completing any boss level in N. Verted Mode will award you with Beat ‘Em Any Which Way.

Complete all 43 levels (38 levels + 5 boss levels) to earn this achievement.

Earn ALL N. Verted Gems

There are a total of 228 N. Verted Gems throughout the game, consisting of 6 N. Verted Gems per level in each of the 38 levels. The boss levels do not contain any gems.

In every level, the six N. Verted Gems are earned by:

• Collecting 40% of the Bumpa Fruit in the level
  
• Collecting 60% of the Bumpa Fruit in the level
  
• Collecting 80% of the Bumpa Fruit in the level
  
• Breaking all of the crates in the level
  
• Die 3 times or less
  
• Finding the Hidden Gem in the level

https://steamproxy.net/sharedfiles/filedetails/?id=2880721747

Arguably the most difficult and the reason (along with the N. Sanely Perfect Relics) that the achievements in this section are so difficult to obtain.
Time trials can be attempted after completing a level for the first time by touching the golden stopwatch at the start of the level, but it is advised to wait until unlocking the Triple Spin which is awarded after finishing the main story.

Unlike the previous titles in the franchise where Gold Relics were enough to score the Time Trial Relic trophies, this game tasks you with earning a Platinum Relic for every level.
Ensure that you have a very thorough understanding of the level layout, as the level must be done in one run as there are no checkpoints.
There are 38 Time Trials to be completed; the 5 boss fight levels do not require Time Trials.

https://steamproxy.net/sharedfiles/filedetails/?id=2876897188


At the conclusion of this incredibly demanding stage, you will receive:

• Faster Than a Tortoise - Earn any Time Trial Relic
  
• Faster Than Sound - Earn ALL of the platinum Time Trial Relics

Earn ALL of the platinum Time Trial Relics / Earn any Time Trial Relic

There are no checkpoint crates, and many crates will be replaced by yellow time crates that stop the clock for either 1, 2 or 3 seconds depending on the number shown on the crate.

There are four types of Time Trial Relics; Sapphire, Gold, Platinum and Developer (Purple).
Unlike the previous titles in the franchise where Gold Relics were enough to score the Time Trial Relic trophies, this game tasks you with earning a Platinum Relic for every level.
Earning a Developer Relic will automatically add to your Platinum Relic count.

Earning any type of Time Trial Relic for the first time will reward you with the Faster Than a Tortoise achievement.

Earning the Platinum Relic for every level will earn you this achievement.

While the Platinum times are difficult to achieve, most can be completed with some room for error. However, some levels to look out for with quite unforgiving times are:

• Rude Awakening
  
• Jetboard Jetty
  
• Draggin' On
  
• Building Bridges
  
• Rock Blocked
  
• Nitro Processing
  
• Toxic Tunnels

N. Sanely Perfect Relics are another new collectible introduced to the series, depicted as the yellow skull and bones icon.
To obtain one, you must play through an entire level without any deaths, while breaking every crate (similar to the crate gems in the original Crash Bandicoot).
There are 38 throughout the game, one for each level (none for boss fights), meaning if you obtain one in the Normal version of a level, it is not required for the N. Verted version of the same level, and vice versa.

It is recommended to go for these after completing the time trials as you will be much more familiar with the level layouts and hazards to successfully completing a no-death run.

Upon completing this task, you will be rewarded with the following achievements:

• Perfectionist - Earn ALL N.Sanely Perfect Relics
  
• So-Called Perfectionist - Earn any N.Sanely Perfect Relic

Earn ALL N.Sanely Perfect Relics / Earn any N.Sanely Perfect Relic

To obtain an N. Sanely Perfect Relic, you must play through an entire level without any deaths, while breaking every crate (similar to the crate gems in the original Crash Bandicoot). There are 38 throughout the game, one for each level (none for boss fights), meaning if you obtain one in the Normal version of a level, it is not required for the N. Verted version of the same level, and vice versa.

You do not need the Hidden Gem or the Wumpa gems in the level (although you may automatically collect 80% Wumpa Fruit while breaking all of the crates in most levels) to get an N. Sanely Perfect Relic.

Upon earning your first N. Sanely Perfect Relic, you will be awarded with the So-Called Perfectionist achievement.

Earn the N. Sanely Perfect Relic on all 38 levels to unlock this achievement.

There are two bonus endings, one at 100% completion and one at 106% completion.
Watch both both to get the rest of the Achievements:

• Master Marsupial - Get EVERY achievement
  
• Overachiever - Watch the 100% bonus ending
  
• OVER-Overachiever - Watch the 106% bonus ending

Watch the 106% bonus ending

To achieve 106% game completion, you must complete all levels and collect all of the collectibles within the game:

• Earn all 228 normal gems, complete all boss fights on Normal mode (48%)
  
• Earn all 228 N. Verted gems, complete all boss fights on N. Verted mode (48%)
  
• Earn all 4 coloured gems (2%)
  
• Earn all 21 Platinum Flashback Relics (2%)
  
• Earn all 38 N. Sanely Perfect Relics (2%)
  
• Earn all 38 Sapphire/Gold Time Trial Relics (2%)
  
• Earn all 38 Platinum Time Trial Relics (2%). Note: Earning all of the Platinum Time Trial Relics will automatically count the percentage for earning all Sapphire/Gold Time Trial relics, thus awarding you with a total of 4%.

On the way to achieve 106% completion, you will achieve 100% completion by collecting all of the gems and defeating all of the bosses (in both normal and N. Verted modes) along with two of the five 2% requirements. This will fulfil the requirements for the Overachiever Achievement.

To access the bonus endings and achieve the trophies, simply bring up the Menu while on the Dimensional Map, then select the Gallery.
Both endings will be available to view in the Gallery.

This will likely be the final achievement to unlock before Master Marsupial
