Chair Entertainment's underwater shooter Undertow is set for release on 21st November, according to an IGN report.
Earlier this week, Microsoft identified it as one of seven Xbox Live Arcade games due out "in the coming weeks", but failed to specify exactly when. Failures!
When it does pop up (or sink down, etc), you will be able to partake of a 15-level single-player campaign of trying to capture underwater bases by hovering next to them and shooting other people who want them. Those other people may include up to 15 of your friends in two multiplayer modes.
Wondering what it all looks like? Then you might want to check out this Undertow trailer. And yes, that is the Unreal Engine 3 bubbling away at its watery heart.
