Closed beta testing of Heroes in the Sky is set to begin tomorrow at 2:00 pm EDT, offering the chance to sample this MMO third-person shooter centering on World War II aerial combat. They are currently accepting sign-ups for the beta, and the first ten users to participate in the beta will win $100.00 USD, while 100 users will be selected randomly through out the day to win $10.00. Here's a bit on the game: "The free-to-play game features fast-paced aerial combat that embodies the intense danger akin to WWII dogfights. In Occupational War Game Mode, players will recreate critical battles of the European and Pacific front complete with WWII planes to help their side take control as they experience epic battles across the history of WWII from both sides! Players will find an easy-to-use upgrade system to help tweak planes and become the ultimate airborne marauder along with additional modifications that will allow players to, not only jam the electronics of their opponent, but also let them keep their own engines cool during boosts. Heroes in the Sky will give players a chance to relive history as they fly dozens of planes from WWII- both experimental and battle hardened - that can be customized to meet their own creative standards."
