Adult Swim has launched a Steam version of Megadev's stylish Super Meat Boy-meets-Ninja Gaiden action-platformer Super House of Dead Ninjas.

Previously released as an online Flash game, Super House of Dead Ninjas hits Steam with a new tower, a batch of new weapons, and 50 additional levels (for a total of 180 stages in all). The Steam version also boasts unlockable Steam achievements and level-sharing via Steamworks. The original game was a lot of fun, and this version has more than enough new content to make it worth a purchase!

Super House of Dead Ninjas is regularly priced at $6.99, but is available for $4.89 through February 25th.
