I've read that about the controls as well but I thought they were fine, I may have changed them on the options though. It is difficult but that is a good thing, I completed it so it's not impossible and you can put it on an easier setting. I've played a lot of games on the PS1 and Alien: Res was one of my favourites, the best fps along with Doom.
Thanks for the welcome FiorinaFury161. Yeah I have AvP but I haven't played AvP2 or Colonial Marines, out of the ones I've played I like Alien: Res the most.
