Humans are way OP
MG turrets acctually do something (3 of them can prevent a maraurder from coming), acid tubes don't. They require assistance from the aliens because humans can shoot them from range and they cannot do the opposite. They are not so much ranged. Useless if you place them in a corner that is impossible to find on most maps. 6 mgs can kill a tyrant easily, but a human with a flamethrower can kill up to 10 acid tubes/ spikers / 3 hives and even come out alive! Speaking of hives, they don't chase the enemy for too long.. Also, when fighting a human, it's hard to kill them even if it's a bot especialy with them moving left and right. It would make much more sense to just "swipe" and to the attack, not point and click and hope that he didn't move away. Also, shotgun is very OP. It is a close range weapon, and considering that aliens are also close range and if you move left-right- they won't hit you at all but if you fire about 4/3 direct shots with a shotgun you will pretty much kill them. Is there any way to balance this out?
