I popped in the my copy for the 360 again two days ago and completed the three campaigns on hard mode.
Still maintain this has one of the best stories of any AvP media out there. No stupid team-ups, no silly hybrids that use guns, the Predator culture is expanded on without clashing with what we saw in the movies (which should always take precedence over their lesser offspring stories).
The gameplay was fun and worked well in single-player, and the campaigns were a very cinematic experience.
Hell, the multiplayer would've been good if it the Preds were balanced properly and the matchmaking wasn't laggy and shit.
This game was killed by a handful of stupid flaws that crippled what was otherwise the best thing to happen to AvP since the PC FPS games.
