Thing is, i didn't understand the reviews AVP3 got. Because i love that game. I didn't experience Verigo or anything like that, The aliens controlled good and it was responsive, and the gameplay and shooting and AI on the aliens were good and they packed a punch. After reading the reviews on A:CM It just looks like a bad game. Buggy, glitchy, broken, dated visuals. Bad gameplay.
I wished A:CM focused on the horror and suvival aspect more. You can still be a bad ass marine with a pulse rifle without having to shoot waves of enemies, if you manage to take down a Xeno, numbers are trival.
