I'm addicted to it. I played for a good 4 hours today. Luckily I'm a master of shooters so taking zombies down isn't to terribly bad but until I found the Telekineses the grenades made me use a couple health boosters. Overall I would say so far I can see why Bioshock was as awarded as it was. Definitely Trippy/Disturbing/Creepy all in one. Awesome Game. My gamertag on the 360 is V1L3 DiaL3cT so go ahead and add me sometime if you want.
