theres a Daedalus Unit (guy that digs to the loneliest person, throws rocks at you (makes you sit) kicks or stabs you with his pickaxe

Theres a Fusilier Unit (guy that shoots grenade shells which you can throw back (easiest of the bunch))

Theres an Achilles Unit (Sniper that deals 90 damage per shot, very quickly finds people that are shootable, has a shield until he finds his target, buffs other units in shield)

those are the main obstacles however there are also cloakers (guys that run at you with insane speed and one-shot sometimes they jump over insane gaps (found by using jetpack) or litterally teleport)

there are infantry (guys that wield machine gun which arent a big problem)

there are shielders (carry a shotgun and shield, shield deflects most bullets)

then there are saboteurs (guys with dual pistols which can throw a sapper drone (saps turrets/teleporters)

there are operators/mechs (mechs shoot out 4 bullets and can stomp anyone that goes under them/above them/touches them idk its a weird hitbox fun fact: you can kill the operator before he gets into a mech and then sit in the mech

finally there are tanks (has a turret and a cannon, for some reason doesnt kill you if you stand infront of it, you can glitch the turret if you stand/crouch inside it)
