Some gamers out there may remember an XBox LIVE Arcade title called Hydrophobia that was teased a couple years ago at E3 2008. Touted as having the most realistic water effects around, the project went utterly silent after that and not much was heard about it after that. However, in the midst of the chaos at PAX East, sharing space with the much in-demand Crackdown 2 demo, was a playable version of a game that combines action-adventure, survival, and third-person shooter genres with one of the most amazing water physics engines I've ever seen.
