Graphically it looks better than seeing pictures of it and it does run smooth. I couldn't really critique it cause i never even finished the demo.
I dislike First person shooters if i find difficulty in aiming the weapon. The concept of injecting yourself with that nectar while the NPC praises it like fine crack is a turn off.
Stories in video games are terrible as it is, but using live actors for some of the cut scenes is the best way to make the graphics and over all feel of the environments even more disappointing. It just doesn't blend.
When FPS games do not appeal to me, I always look back to Halo 1 to remind me why i ever liked FPS games. I played so many and I think Halo is the best FPS ever made. Out of Halo 1, 2, and 3, Halo 1 is the true masterpiece of the line, and the best FPS in my opinion.
