Bioshock

I just played the demo of Bioshock and I would have to describe it as super cool. Set in a 50's era undersea utopia, it is now filled with mutants and monsters, the result of unethical medical experiments gone awry. The demo wasn't very long, so it was hard to get a good feel for the gameplay, but what I saw I liked. The graphics are absolutely gorgeous, and the atmosphere is really creepy. It was like stepping into a Steven King novel.

The real novelty of the game is that you can find "plasmids" - injections that will manipulate your genes and give you super powers. I found the electricity plasmid that allowed me to shoot bolts of lightening from my hands like the emperor. I also found the incinerate plasmid which allowed me to set enemies on fire. I saw a short video that said there were also teleportation and telekinesis plasmids and others.

After playing the demo, I'm dying to play more. I just hope the rest of the game is as good as the beginning.
