Orcs Must Die! Unchained Open Beta

The tag on the Orcs Must Die! Unchained website has changed from "closed beta" to "open beta," signifying the change in status for the latest installment in this tower defense series. They offer new bundles, new referral rewards, and a new roster of heroes of the week to mark the occasion. A new open beta trailer offers a look, and here's word on the beta:
Gameforge and developers Robot Entertainment are headed into the home straight with the third entry in successful action tower defence series Orcs Must Die! – their joint project Orcs Must Die! Unchained today enters open beta. Now all can join in on the fun without any game entry restrictions. Once they log in, players can head into Survival mode with friends or face other players in the Siege mode. To defend their rifts they can build traps and use a range of weapons in order to blow countless orcs to kingdom come, thus following the grand Orcs Must Die tradition.
