Looks like the closed beta was a success, as Robot Entertainment announced this morning that an Open Beta for Orcs Must Die! Unchained will be coming next week on March 29th. If you participated in the closed beta, it is over and your accounts will be closed and wiped clean starting everyone a fresh start. However, one good bit of news is that those that participate in the closed beta will not have to start over from in-game gold purchases, as any purchases will be honored and carried forward into the open beta at an adjusted rate. In addition, the Alpha Founder pack content will also be applied to accounts when they roll forward.
In order to participate in the open beta, you must download the game on Steam or off of orcsmustdie.com on March 29th and create an account.
