Orcs Must Die! Unchained will be getting a hefty update on Tuesday, January 17th. A trio of new battlegrounds are incoming for high-end players as well as a new leaderboard display during the fight on each map. Players will also receive three daily quests, one for experience, one for a chest and one for skulls. The store will feature rotating goods each day, three different bundles of cards, with six on Sundays. Bundles can be purchased with in-game currency (skulls).
You can see the gist of the patch notes on the Orcs Must Die! Unchained site.
