Pieces of crap, they always use super-overused weapons such as the SCAR-H, Winchester 1887, Barrett .50 Rifle, and so on.
Hands look stupid, forces hand color. We also don't need stupid ammo system manually enforced, I am not against reloading guns, but I don't like ammo. They don't ever look cartoonish, or made of plastic, which sucks.
They also are seriously underpowered, I mean, survive after taking 10 bullets? Really?
