Looks like Typing of the Dead on STEAM will feature online co-op for both Typing and Overkill mode. May post that later on the list.

While I do have the game on PS3, my system has the YLOD, but it is considered. Hopefully once I get done with my school work, we can possibly play both Sonic Lost World on WiiU and the Model 2 Collection this month.
