Ubisoft has a free Flash based game up right now for H.A.W.X. The game itself is made to look like an 8-bit game that may conjure up memories of such games like 1942 and 1943. It’s a top down shooter that is actually very well made and fun to play even though it’s free.
You can play the game here. As an added bonus, by playing the free online mini-game you’ll be able to unlock exclusive content for H.A.W.X.2 when its released for Xbox 360, PlayStation 3, Nintendo Wii and PC.
