BioShock Demo is up on Marketplace

[Vampyr]

Sadly it's my little brothers 360, and since I'll be going to college in a week I don't have my own gamertag. But I've enjoyed it so much, I'm contemplating buying my own.

I will post impressions once I've played it though, and when I have my own I'll get my gamertag up.

Halo 3 is proving too much to resist.
