Dungeon Defenders is something that I'm quite excited about, a game that should be able to equal the high quality of Orcs Must Die! while also having some great cooperative gameplay. Last month we went into some detail about all of the classes in Dungeon Defenders, but now Trendy Entertainment has released a video explaining all of the game's rpg mechanics. They show off pet's, stats, hero swapping, trading and all kinds of customization options. Also, they recently announced that the PC version of Dungeon Defenders will have some special pre-order bonuses. The pre-order bonus has something to do with Team Fortress 2 merging into the game, along with some weapon from Portal, watch the video to find out. All in all just a few more reasons to get excited about this tower defense, rpg, action hybrid.
