Your free copy of Undertow is up and ready to get from your Xbox 360 Dashboard. Just make your way to the store and download your very own copy of this underappreciated XBLA game.

For those who didn't pick it up the first time, here's a quick reminder:

"Undertow is a fast-paced action-shooter that sends you underwater as you battle up to 16 players for control of the oceans! Non-stop conquest-style battles push the envelope of onscreen effects and combat action and boast some of the most stunning graphics ever seen in an Xbox LIVE Arcade title."
