• Eight-player cooperative and DukeMatch multiplayer: Play ranked matches in one-on-one or free-for-all for leaderboard spots. A playlist of levels keeps the game fresh, with levels rotating on and off the list. Play co-op with your friends, earning single player achievements or completing the game entirely. It's your choice how to play. By reserving private slots you can play with your friends or with strangers in any combination. Invite away.
• User clips: Every time you play a game, a user clip is recorded. View the clips any time in your theater or share with friends who own the game. Upload the clips to leaderboard spots if you complete a level in the fastest time, or if you have the highest score. Use these clips for tips on how to complete a level at speed.
• Painless death: Review your play from the start of the level right up until your death, and jump back in at any point. Go back 10 seconds or 10 minutes, the choice is up to you. You can still save and load your game at any point if you prefer.
