To be fair, the Aliens on Marines action in the original AvP was Alien and Marine action done right. If you didn't rely on your tech you were mincemeat.
It seems like ACM is kind of going for this in the MP of the game, but the SP looks more along the standard AvP2 onward fare. Heavy scripted sequences where the Aliens are dangerous in a swarm as oppossed to being able to rip you limb from limb as a lone creature.
I'm getting it regardless. But I'm also going to download AVM and beat off to it for nostalgia sake.
