Saw it in action today, and got to play with it for about 20 mins..and I am extremely impressed, the graphics are beautiful, the sound effects are great, the background sound is amazing, the worlds look so cool, and the way it plays, it is just awesome..the sounds from the aliens and stuff..very scary and freaky, the way the AI movies, just awesome..I can't explain it..the animations, so smooth and alien-like..the way they try to rip you apart, its perfect! The game is definitely going to challenge Doom 3..I'm sort of speechless, the game is just awesome..every part, is amazing. It is sort of similar to Half-Life, but basically improved upon everything. So far i've only seen like 4 weapons, but they are all really cool..the models look great. I can tell a lot of work went into this game, the voice acting, cutscenes, audio, video, etc..are all top notch..they are perfect. You might think it's sort of like Unreal Tournament 2003, but it's not..the only thing that is similar is the graphics, but the graphics are much better in Unreal 2. I soo want to play more, I wish I never left!!
oh yeah, from the hour or so I watched, I would give this game an easy 10 out of 10..you must see it in action to understand what i'm saying.
