Using Vita-Chambers will make Bioshock 2 game world "different," says 2K
2K Marin's Melissa Miller, senior producer on Bioshock 2, has told MTV that using Vita-Chambers in Bioshock 2 will make the game seem "very different."
Apparently, the default Vita-Chamber setting will be "off," but enabling them will not only regenerate your health, but also that of your enemies.
There's plenty more through the link.
Bioshock 2 comes out later this year on PC, PS3 and Xbox 360.
