This DLC will conclude the journey as you take on the tyranny of King Washington in the hopes of stopping it

You can grab a copy for $7.99 on the PS3 and PC or 640 MP on the Xbox 360. For Season Pass holders, all you need to do is flash your pass, as Redemption is part of the all give Assassin's Creed 3 DLC packs.

Skullgirls patch coming to XBLA

The major patch from Lab Zero Games is finally coming to the XBLA, so better get ready for some changes and fixes to Skullgirls.

EuroGamer reports that the update, which is 590 MB's worth of changes, contains the same patch that was rolled out for the PS3. The reason that it didn't appear in XBLA was due to policy conflicts, but thankfully, this has been remedied.

Among the changes that you can expect include expanded Training modes, the addition of a single-player Nightmare Mode, better performance online, character skins, eight DLC character color packs, and character tutorials, to name a few.
