It's a rare treat to see a game that was previously non-cooperative gain co-op support. That's just what happened to Tetris Forever this week. The third game in Digital Eclipse's Gold Master Series (which also contains the delightfully quirky Llamasoft: The Jeff Minter Story) is a collection of new and classic Tetris games from throughout the franchise's history, plus documentary content. The arrival of Super Tetris, which supports 2-player local co-op, pushes the game count up to 21. That's a lotta Tetris!
