I also made a Shop Version of this Guide, check it out, Here

So, first up, there are 3 Types of Enemies:

Tier 1
Tier 2
Tier 3

Every Enemy is in one of these Categories!

These Categories decide, what to spawn on what Level:

Level 1-2
1x T1
1x T3

Level 3-5
1x T1
1x T2
1x T3

Level 6-8
2x T1
2x T2
2x T3

Level 9
2x T1
3x T2
2x T3

Level 10-19
2x T1
3x T2
3x T3

Level 20+
3x T1
4x T2
4x T3




Sometimes, you may see way more T1 or T2 Enemies then you should. This is because theres about a 5% Chance a T3 Enemy gets replaced by a group of T1's or T2's here's a list of the Ammounts for them:

10x Gnomes
4x Apex Predator (Duck)
4x Spewer
3x Peeper (Eye)
3x Rugrat
4x Shadow Child
3x Animal
3x Upscream
6x Banger
3x Bowtie
2x Hidden
3x Mentalist (Alien)
3x Chef (Frog)


At the Start of a Level, Monsters will spawn at the room furthest from the Van.
When Spawned, they will stand "AFK" at their spawn location for an ammount of time, depending on the Level:

1-120-180 s
2-108-162 s
3-66-102 s
4-39-59 s
5-27-41 s
6-24-36s
7-23-35 s
8-21-32 s
9-17-26 s
10-11-26 s
11-0 s

If the player is within 20 Units (U) of an Enemy, that Enemy will skip the rest of its AFK -Time!

This is about 20 Units (U):













The C.A.R.T is about 2 Units Long:

















Despawning and Timers:

As soon as an Enemy Spawns, its first Despawn Countdown will begin. This countdown is 3-4 Minutes long. It will run and cannot be stopped or slowed down, unless the Enemy is killed.

After the first countdown, a second one starts. This one is 20-40 seconds long. After this countdown, the Enemy will despawn! But, if a player is within 20 Units (U) of an Enemy this countdown stops and keeps ticking, after the Player is gone. The countdown doesnt get increases, just stopped temporarily.
Enemies also despawn, when they are stuck and cannot find a way to move after a while.

Once it is Despawned, a Spawning Timer will begin that is dependant on the duration you've been in the current Level:

Enemies Move along "Levelpoints" when not distracted by players, sounds, etc.



There are no Levelpoints in Extraction Rooms (exception-first extract) so you wont find them in those rooms unless they are following a player or noise.



Vision:

Enemies have these "Vision-Cones"

Depending on your current State, this Cone has a different Size:

Standing:












Crouching:














Crawling/Hiding (Crouching under an Object):












For an Enemy to spot you, you have to be inside their Vision-Cone for:
1 Second if Standing (100% Vision)
2.5 Seconds if Crouching (80% Vision)
5 Seconds if Hiding (40% Vision)


They also have promimity Bubbles!
If a player is inside the Bubble of an Enemy, it will instantly spot them.

There are 2 Sizes:

Standing:











Crouching or Hiding:












Generally all Enemies have the same Cones and Bubbles, there are exceptions though like the Huntsman (Blind) and Special Enemies that dont move around and act like others, like the Peeper.








Noise Detection:

Most Enemies in the Game can hear!
Noises make Sound Bubbles.

If an Enemy is in that Noise Bubble, it will go to the Center (origin Point) and investigate.

Walking and Using most Items make small Sound Bubbles, while Sprinting and using Guns make bigger ones. Shotgun, instruments and breaking Items make huge Bubbles.

Crouching doesnt make Noise, so feel free to roam around next to Enemies!










The Huntsman hears 5x better then all other Enemies, so if a Bubble is 5Units wide, he can hear it from 25 Units away!

Extraction Points make gigantic Bubbles to Alert Enemies.

After the Final Extraction, the Van gets a huge 100Unit Bubble 4 Times.
After, a random Level Point in the Room of a random Player will be pinged every 1,3,5,7,..., max: 30 seconds.

When an Enemy is killed, they drop an Orb.

These are Valuables, that come in 3 Sizes which drop from their respective Tiers:



Large T3 - 6-7k
Medium T2 - 4-5k
Small T1 - 2-3k

After dropping, the Orb will be White for 5 Seconds, during this time, it is Indestructible!
After this, it will turn Pink, and be VERY Fragile.

A maximum of 3 can drop from the Same Enemy, so you cant Farm infinite Money with these, but they are still a huge source of Cash!

After Level 20+ Orbs can be used as Explosives, altough very impracticle. In a pinch you can trow one at an Enemy to make them explode, giving you time to escape.

Weight:

Most Enemies have a Weight. The Ammount of Strength Upgrades needed to pick it up is its Weight.
If you can pick it up, you can either Slam it against the Ceiling, Walls or Floor over and over again, or trow it in a Pit!
Be careful with Pits though, since the Orb will break if it doesnt reach the Ground safely after its 5 seconds.


Tumbling:

By pressing "Q" you can Tumble, which is used for Movement or hiding in a pinch, but it can also be used to Attack!
With enough speed during a Tumble, hitting an Enemy will deal 15 Damage to them (and Knock down Small Enemies) but YOU will also take 5 Damage, so you should only use it if an Enemy is already low on HP. You can do this with 0 Upgrades by Sliding--->Jumping--->Tumbling.


Scroll-Wheeling:
With Small and Medium Items, you can attack Monsters!
Using your Scroll Wheel you can move an Item further and closer, do it quickly into an Enemy to hit it! Medium Items do way more damage, last longer, and stun more Enemies!
Perfect for Early Game, no Strength required, but Strength makes it easier and stronger.


Animation Buffer:
When an Enemy Crouches Down to look for you in Hiding Spots, it is STUCK in that Animation until it's over. Bait an Enemy to look down, during it, run as far as you can. Easy way to escape the Robe and Headman!


Melee Weapons:
The Best Melee Weapons are:

Sword ---> ~25k good for Early Game 50 Damage
Sledge Hammer ---> ~45k good for Mid Game 150 Damage + Stun for Most Enemies


Ranged Weapons:
The Best Ranged Weapons are:

Gun ---> ~20k good for Early Game 80 Damage
Photon Blaster ---> ~45k Good for Mid Game 5x35 Damage per Shot Better vs. Groups
Shotgun ---> ~45k Good for Mid- Late Game 5x50 Damage per shot Better vs. Single Enemies


Explosives:
The Best Explosives are by far:

Grenade ---> 3k 160 Damage + Stun
Duct Taped Grenades ---> 2k 4x100 Damage + Stun(s)
