i finished the alien campaign recently.
and the marines much earlier than that but i cant be bothered finishing the predator one, got too lost.
although i hate the aliens because they are a parasitic race, their fighting style is my favourite.
all vicious melee assaults.
im the type of guy who spares the lives of unarmed living targets like those scientists but the way they cower and say "G-g-god!" pisses me off and then i dont hesitate to eat them.
