Tripwire Interactive announces they are adding three new maps to the multiplayer beta test for Red Orchestra 2: Heroes of Stalingrad, bringing the number of maps in the testing of their upcoming World War II first-person shooter sequel to six. The maps, Grain Elevator, Red October Factory, and Barracks, go live today, and all three include both Territory and Countdown game modes, while Barracks also supports Firefight mode. The beta is open to anyone who pre-purchased the Digital Deluxe Edition of the game on Steam, and for those who have pre-purchased the vanilla edition, they are also now selling a separate upgrade to the Deluxe Edition for $9.99 USD.
