Arcade-shooter Thunder Wolves will be available for pre-order on Steam today with a discount of 20% off the regular price of €14.99, bitComposer Games has announced.

Thunder Wolves puts you in the hot seat of an experienced helicopter group that has survived a bullet mayhem. There will be a variety of missions including high-risk convoy protection, deploying a commando on fast-moving train or unleashing hell on the battlefield.

Nine different types of helicopters are featured which you can upgrade with additional weapons and defensive tools to create the ultimate aerial hunter. Thunder Wolves will also include two-player local co-op – one gamer playing as the pilot and another as the gunner – giving you the opportunity to establish aerial dominance with a friend.

Thunder Wolves will be released on Steam on May 15th. The game will also be released on the PS3 and Xbox 360.
