EuroGamer has reviewed Aliens Vs Predator: Requiem for the PSP, based on the movie of the same name, giving it a 4.0 out of 10 rating. Seems as though they believe the game to be VERY average and nothing special.

From the article:
‘Which sums up Alien vs. Predator: Requiem. It’s not a badly made game. With the exception of the camera, everything works. It looks all right. It’s not the worst videogame we’ve ever played, and it’s certainly not the worst movie tie-in. But it’s entirely lacking in imagination and innovation. There’s nothing that hasn’t been done before and no incentive to keep playing. A month from now we’ll probably have forgotten we’ve ever played it. But by then we’ll be in negotiations with Peter Bowles’s agent, obviously.’
