There's a few co-op games coming to consoles this week.
First up is Lode Runner for the Xbox Live Arcade. The game features 2 player local and online co-op through what the game calls a "journey campaign." I imagine fans of the classic game are going to at least want to give the demo a download.
Next up is Dynasty Warriors Gundam 2. The game is a mix of the classic Dynasty Warriors formula combined with the popular giant robot Anime series Gundam. The game features 2 player local co-op as you hack and slash (or punch and slam) your way through the waves of robot baddies. Dynasty Warriors Gundam 2 is available for the PlayStation 3, PlayStation 2 and Xbox 360.
