Orcs Must Die! Unchained is set in the familiar world of its humorous fantasy predecessors, years after the finale of Orcs Must Die! 2. With the discovery of dozens of new rifts and magical worlds beyond them, heroes have come from far and wide to wage all-out war for control of these valuable gateways. In the years since Orcs Must Die! 2, the War Mage and Sorceress have rebuilt the once-mighty Order. Their new enemy, the Unchained, is not the mindless horde defeated twice before, but instead an organized army led by powerful heroes.

Orcs Must Die! Unchained finds players joining forces, charging in with teams of heroes that battle head-to-head to attack and defend ancient strongholds. For the first time in Orcs Must Die!, teams of players will be responsible for both sides of the battle, building traps to stop enemy assaults while summoning their own armies to lead in siege 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!

With the open beta phase approaching fast, Robot Entertainment just launched a significant update to Orcs Must Die! Unchainedthat includes a number of new game changes and enhancements.

Key changes and updates include:

• Campaign Mode: This is a whole new way to play the survival game mode. Players can now battle across more than 50 challenges as they level their account and upgrade traps.
• Tinkering: Traps have always been the core of Orcs Must Die and with this update, players can now upgrade their traps, improve their stats and visuals, and apply new parts to customize their traps' operation.
• Additional Maps, Traps, Traits, and Survival Minions: This update includes three new survival maps, five new traps, five new traits, and four new survival minions.
• Meta Revamp: The entire meta-game has been updated to provide a more fun and rewarding experience. The skull store has been removed. All cards are either now crafted with materials that drop during games, picked up through the new salvage system, rewarded from quests, or are dropped in chests. The dashboard UI has been updated with an all-new "workshop" to provide a one-stop shop for all things crafting-related.
• Role System Revamp: Predetermined hero roles are gone. Players can now select any role they wish as a perk during hero selection. Each role provides associated bonuses.
