Earlier this week, Trendy Entertainment announced that Dungeon Defenders 2—a follow-up to the co-op action tower defense original—will be free-to-play and feature a competitive MOBA mode. The new mode is already in closed beta, but the continuation of DunDef's co-op won't be playable until later this year. Even so, Trendy has released a pre-alpha co-op gameplay trailer—it's bigger and prettier, but doesn't look to stray from the original in any fundamental way.
Dungeon Defenders 2
Dungeon Defenders is a fun co-op action tower defense game. Dungeon Defenders II, announced today by Trendy Entertainment, is that idea give or take everything that's happened in PC gaming over the past three years. It's free-to-play with cross-platform multiplayer (PC, Mac, iOS, Android, and Web), and it's launching in two parts: a new competitive MOBA mode that's in closed beta now and will be playable at PAX East this week in Boston, and an update to the cooperative defense mode of the original, which is scheduled for beta late this year or early next. So, not much has changed.
