Reserving a game doesn't always get you small stuff like a poster or t-shirt. Throwing down money to pre-purchase Tom Clancy's H.A.W.X., for example, will get you a free game.

Pre-purchasing the game through Steam will earn you another combat flight sim from Ubisoft: Blazing Angels: Squadrons of WWII. Blazing Angels allows you fly 39 different planes from World War II in 40 single-player missions and 10 multiplayer modes. Ordinarily, it would cost you $9.99 to purchase it through Steam.

H.A.W.X. will be available for download through Steam on March 11th. You'll be able to play Blazing Angels as soon as you throw down the money for H.A.W.X., though. This is the second "buy one, get one free" offer Steam has offered this week for Ubisoft titles. On Thursday, they began offering a free copy of Tom Clancy's Ghost Recon Advanced Warfighter to anyone who pre-ordered EndWar.
