While the first two Orcs Must Die games from Robot Entertainment were built around tower defense gameplay mechanics, the third installment in the series is getting more competitive with Orcs Must Die! Unchained.
Robot Entertainment has released a reveal trailer for Orcs Must Die! Unchained, which is described as a fast-paced Fortress Siege action game in which teams of heroes battle head-to-head to attack and defend ancient strongholds. 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.
Unchained will also feature card game elements, giving players the ability to collect and upgrade heroes, weapons, traps, and minions. Orcs Must Die! Unchained is due to launch in late-2014 with a free-to-play model.
