Free DLC next week with new plasmids and a mode to turn off vita-chambers, and a widescreen fix:
BioShock Patches, Free Plasmid DLC to Hit Next Week (Updated) - Shacknews - PC Games, PlayStation, Xbox 360 and Wii video game news, previews and downloads
This late in the game it's hard to care but still cool they're doing it. I'll probably get around to playing it again in like February though.
And yeah Blank those trap ones were pretty funny, I never mixed them with fire though, which sounds like a pretty good idea now.
