Do you really want to go there?
you realized that the majority of the marines were wiped out in the fist encounter or are you just ignorant?
you also realized that the majority of xeno casualties was achieved through the survivors camping and forcing the Xeno's through a kill box or did you think they are mindless beasts that charge at them? because if you do your being ignorant again as the Xeno's did not necessarily zerg rush but went over the barricade making almost all the survivor's prep useless.
And do you also realize that the Xeno's actually beat the Terminators in a cross over and have more wins over Predators?
Since you seem to be the expert : how many xenos were killed by a dozen of space marines in the movie Aliens ? And how many of them were killed by a non-fighting woman with a gun and a flame-thrower ?
Whats funny is the Aliens were Stupid and did ZERG RUSh the Sentry guns twice like idiots. Then they figured a way in.
So no they were not all that smart at all.
They charged the Guns like Idiots till the guns ran dry LOL.
, in the cannon movie there were no sentries just the barricades, they went over the barricades.
do you want me to show the scene where a T-800 gets disabled by a Pipe Bomb?
or killed by a shot gun blast to the head durp?
so much for their intelligence.
