They have only long range, bad vision in the dark, there light needs to recharge, and of course they have the hardest time regaining life/armor and ammo. Not to mention their the slowest of the three. Have fun gunning down a wave of Aliens when you have to reload...or face a Predator you can't even locate. Plus the radar only works in the direction their facing.
Wow...they really made the marines realistic, lets face it...when it's AvP we humans just die and thats that
I remember last level of AvP (before the bonus levels that is) I had to take on the alien queen with nothing but a spear gun and wrist blades...she killed me once and then I was able to beat her but as a marine I get the chances she'd kick my ass
That didn't happen in no.1, I think I may have chopped one of her arms off with the spear gun as well unless I had hit her somewhere to make her keep splurting out blood which isn't really something that happens in those games but it helped to see her. I just kept shooting the hell outta her, finally she died but damn she wouldn't go down faster than a thai hooker...I dunno if my shoulder cannon or pistol woulda made much difference but they weren't allowed since it woulda been bad for my honor or some crap like that.
