I haven't actually tried it out yet, I just read a news article about it. It's a Tower Defense type of game that takes place after the recent oil rig explosion. I live on the Gulf Coast and recently had oil wash up on our beaches here, so this kind of hits home a bit. Apparently you use subs to shoot oil globs coming from the oil well.
