Trendy Entertainment has announced Dungeon Defenders II, and it will have two distinct modes: cooperative and competitive. The cooperative mode will be similar to what you're familiar with in the first game. The competitive mode will be 5 vs. 5 MOBA gameplay. The other news is that the game, including both modes, will be free-to-play with microtransactions for heroes and cosmetic items. For more details, see the official site's FAQ page.
