• Total achievements: 50
  
• Missable achievements: 0
  
• Minimum number of playthroughs: 1
  
• Estimated time to get 100%: 25-50 hours

1. Finish the Main Campaign with one character. Enjoy the story at your own pace by playing on any difficulty you want, as there are no difficulty-specific achievements tied to the main storyline, so stick with a character you are comfortable with.
2. Complete all Support Squad Missions and Riddler Collectible.
3. After completing the story, you will gain access to Incursion Missions, which help you reach the max level (Level 30) with all 4 characters and help you reach Squad Level 50.
4. XP grinding and gearing up for Infamy Gear Sets.
4. Achievement cleanup: squad contracts, hit squads, etc. (refer to 7. Combat Achievements)

Note: To save yourself the grind to 100 contracts, try to work on and complete as many contracts as you can while playing through the story.

The 14 story-related achievements presented below are those that are unlocked throughout the main campaign. Most of them can be unlocked naturally when finishing 6 chapters. Some achievements like "History Repeats" may be missed in the first playthrough but can be obtained by Chapter Select.

Support Squal Missions appear when we progress through the main campaign.

The 7 characters are Lex Luthor, Rick Flag, the Penguin, Gizmo, Hack, the Toymaker, and Poison Ivy.

Completing one from, for example, Lex DOES NOT MEAN that he will instantly give us another one from him, but rather that one from anyone else will appear, keep in mind what has been mentioned.

Riddler collectibles can be divided into 3 sections:

1. Riddler's Riddle
   
2. Riddler's Trophies
   
3. Riddler's AR Challenges

Please use the following guide made by シ to complete section [1] and section [2].

For the last section, Riddler's AR Challenges, even though the game indicates that they are made especially for EACH CHARACTER, but you can do them all with one and they will still give you the achievements. Deadshot is recommended for collecting all the stars.

Messaggio originale di Vanadio:

I personally used Deadshot in all of them.

There are 21 Riddles, which can be found all over Metropolis. Each sector has 3 Riddles for you to solve. The achievements related to RIDDLES are the following:



There are 40 trophies, which will automatically be marked to your map during combat or travel in Metropolis. The achievements related to TROPHIES are the following:



There are 13 AR Challenges with 3 stars for each one, which are unlocked in Metropolis sectors by progressing through the story. The achievements related to the AR CHALLENGES are the following:

Incursion Missions are the main post-game activities, where you can complete missions in Earth - 2 to level up to Mastery Levels and get Infamy Gear Sets. In order to access these challenging missions, you must first defeat Brainiac to end the main story. Afterwards, you'll be able to play 3 different Incursion Missions:

• Invasive Species: Defend the Poison Ivy plant.
  
• World's Un-Fair: Destroy the Incubators of points A, B and C.
  
• Sending A Signal: Kill enemies to provide charge to the Terminauts the Jammer.

Each Incursion Mission will cost you 1,000 Promethium (per each real player if you go), which can be obtained either by completing activities around Metropolis or by defeating Cargonauts (otherwise called Lootinauts by Hack). Cargonauts are the small, octopus-looking enemies with 4 tentacles that are usually hiding on the side of a building (they can be found with a Lootinaut Tracker whenever Hack tells you that one is present in the nearby area).







KEEP IN MIND
You can NOT repeat the same Incursion Missions to level up to level 20, for example, if you did the Ivy missions from Mastery 1, you would go up to Mastery 2, but if you play Mastery 2, you would no longer go up to Mastery 3. The game FORCES you to be playing all 3 raids one after the other. I recommend doing the order Ivy/Inhibitors/Picking.

The following achievements can be obtained at the same time if you join another person's game and complete an Incursion Mission at Mastery Level +20 or higher.




UPDATE: It can only done in Finite Crisis. The Scarecrow infamy set in Season 1 elseworld NOT WORK. It need Bane's infamy set gear pieces. (Credit to Rickyel™)

For these 3 achievements related to the Infamy Gear Sets, you will need to obtain and equip 3 pieces from all 3 tiers.




In order to unlock a Villain Synergy, you will need to grind along until you find a Notorious Villain item, which are colored pink and tied to a certain DC villain. And you will also need an Infamy Set item (colored red).

The only Infamy Set that’s available right now is the Bane Infamy Set – more will be added to the game as the seasons progress. The available villain synergies at this time are:

• Bane + Two Face
  
• Bane + Black Mask
  
• Bane + Hugo Strange
  
• Bane + Merlyn

For example, you can see that the weapon in the image below is tied to Bizarro and is coloured pink – a Notorious Villain item.

You will obtain Level Up for getting any Squad Member to Level 10, and all 4 characters have a trophy tied to them for reaching Level 30. Once you either have any character to level 30 or everyone at level 30, you can start gaining Squad Levels, which will still require tons of XP overall.

Messaggio originale di Vanadio:

There are 3 methods to farm faster exp (At least until Mar 3, 2024).

METHOD 1 (THE FASTEST, BUT FINITE)

It consists of entering the incursion of the image and repeating it over and over again. (The higher the mastery, the better the reward and the higher the XP.)

I RECOMMEND USING DEADSHOT WITH BOMBER BUILD

PROS

CONS

• Duration depends on our speed. (Approx 3 min).
  
• The higher the difficulty, the more XP.

• It requires 1000 P, so you'll need to farm more.
  
• Boring to repeat the same mission over and over again.

METHOD 2 (THE SLOWEST, AFK FARM)

It consists of entering CHAPTER 4, episode JUST A PHASE and progress until Lex has the portal but DON'T ENTER and stay making counterattacks against the infinite waves that are coming. (It is advisable to increase the overall difficulty to Mastery 5 to gain more XP.)

PROS

CONS

• Afk Farm by allies. (The AI).
  
• The higher the Mastery (General Difficulty of the game), the more XP.

• Too much time to level.
  
• You may be pushed away by the enemy and finish the mission.

METHOD 3 (THE REALLY FASTEST, BUT SUPPOSEDLY PATCHED)

I couldn't tell you much about this one, to be honest, since I COULDN'T DO IT because you can only do it if you don't finish the Gizmo missions, which consisted of killing enemies with the vehicle and not delivering the items, having infinite waves.

Supposedly, it's PATCHED but I'll still leave you a video guide in case you're interested in trying.

Probably many of these achievements will unlock by playing the main story, but I will put how to do them.

Support Squad Contracts are small assignments from your Support Squad members, who will ask you to perform various actions or kills while playing the game. To view these contracts, open up your menu and go over to the Contracts tab, where you'll be able to pick and choose which contracts you would like to work on simultaneously.

As you complete Support Squad Missions for Hack, you will be able to have more contract offers become available from your Support Squad Members, which will also allow you to work on more contracts simultaneously.


To save yourself the grind to 100 contracts, try to work on and complete as many contracts as you can while playing through the story.

Here are some examples of recommended contracts:

• Kill x enemies in this district
  
• Kill x enemies with this type of weapon
  
• Complete x amount of specific missions
  
• Afflict x amount of enemies in this district with any affliction

By this point you should have 50 ACHIEVEMENTS!

I simply hope that I have been able to guide and/or help whoever wants to 100% the Suicide Squad: Kill The Justice League.
