For the first time in Orcs Must Die!, teams of players are responsible for both sides of the battle -- building traps to stop the enemy assault AND summoning their own armies to lead against the enemy defense.

White-knuckle Fortress Siege action puts you into the thick of competitive siege warfare. Unleash your minions and charge into the heart of the enemy stronghold and build an impenetrable gauntlet of traps to hack, grind, flatten, gibletize and incinerate your foes. Your team must master both tactics to triumph.

Dozens of unique and powerful heroes offer deep gameplay options at all skill levels. Old friends the War Mage and Sorceress return to face new enemy heroes like Blackpaw, Midnight, Stinkeye, and Bloodspike. Whether players prefer might and majesty or scum and villainy, there’s a hero for everyone.

Collect and upgrade powerful heroes, over-the-top weapons, devious traps and fiendish minions. Build an arsenal from an enormous variety of options, and customize a strategy for every match. New heroes, weapons, traps, and minions are continuously added, and your collection will never stop evolving!
