Robot Entertainment announces Orcs Must Die, a fantasy-themed action/strategy game from this developer formed by veterans of Ensemble Studios. The game's product section is online, we have some screenshots, and the announcement trailer shows off some fast and furious action. Here's a bit: "Orcs Must Die! challenges players to defend fortresses under siege. With a wide variety of traps and weapons to choose from, Orcs Must Die! dares players to find the best ways to hack, launch, flatten, gibletize, and incinerate an endless army of filthy orcs and their vile allies. Orcs Must Die! features a vibrant look, addictive gameplay, and a blatant disregard for the welfare of orcs." The embedded trailer follows.
