Monsters

Monsters spawn in increasing difficulty every ~3 minutes. The difficulty levels can be thought of like the following:

These monsters spawn in abundance and fill the map in hordes. They are generally weak with little to no special attacks and attributes but their strength comes in numbers.

Glass cannon monsters have low health but make up for it in terms of agility and special abilities, namely flight and in case of mite explosions in case of spiders.

Agile monsters have medium to low health but have fast agility and can catch players off guard, being able to leap and zig zag!

Snatchers have pretty high health and can disrupt players significantly due to their snatching abilities that disrupt players from shooting and moving

Brutes have high health, high basic attack damage, and damage resistance. They are also agile being able to dash, turn invisible, etc. Sometimes their basic attacks will also apply effects like poison

kamikazes are annoying both when they are alive and dead. Killing them can sometimes bring you more pain if you're not careful, e.g by spawning other tiny mobs or leaving behind a poison cloud

Bosses, if you've played video games, you should know what they are by now! Lots of crazy special attacks, ability to break through walls and do terrain damage, just an utter nuisance!

The original TLC Byond version limits the maximum amount of monsters like so:

1. max_zombies = 800
2. max_crows_mites = 15
3. max_dogs_carriors = 10
4. max_lickers_spinners = 15
5. max_hunters = 20
6. max_venuss_bbwidow = 15
7. max_roachmans = 10
