With a redesigned spellbook, players will have a broader range of options to build a deadly arsenal of defenses. Investing hard-earned skulls in an enormous new upgrade system will allow players to cater to their favorite methods of burning, grinding, tossing, or dismembering orcs.

Orcs Must Die! 2 begins days after the ending of the original game. With the rifts closed and the magical Order dead, the War Mage finds himself suddenly thrust into a new battle against the mindless orc mob. He has a powerful, if questionable, new companion in the Sorceress, an ex-War Mage responsible for the destruction of the Order.

The Fire & Water Booster Pack features three brand new levels and three new Endless Mode conversions that can be played in single-player or with a friend in co-op. Players who download the pack will also find a new array of traps to help them combat terrifying new elemental enemies.

Hellish new Fire Lords and Fire Elementals crumble when killed, leaving behind dangerous Firelings that will hunt the player down and explode when they get too close! Slippery Water Lords and Water Elementals dwindle into pools of water when killed, but don't count them out of the fight! When Waterlings find dormant puddles, they'll absorb the stagnant water and grow into new Water Elementals!

War Mages will have access to three exciting new traps to add to their arsenal, as well.  The Web Spinner is a new wall trap that ensnares hallways full of passing monsters in a sticky tangle of webs, slowing them down to buy precious time. Ceiling Darts turn your fortress into a temple of doom for orcs, dropping from the ceiling to fire deadly darts in every direction. If the orcs make it past your defenses the first time around, you can give them another dose of pain with the new Floor Portal. Place the floor portal anywhere on the ground. Unsuspecting enemies who step on it will be magically teleported back to the beginning of the level!
