Dungeon Defenders, the outstanding tower defence/RPG hybrid from Trendy Entertainment, will be free to play this weekend on Steam. Festivities kick off this afternoon at 17:00 GMT, and you can start pre-loading now. If you've yet to experience it, I'd suggest checking out our 9/10 Dungeon Defenders Review.
The base game and expansions will also be 50% off this weekend. We'll update when Steam make it official.
