Altitude, the 2D multiplayer aerial combat game, goes free on Steam
It's a cute, cartoony little 2D multiplayer aerial combat game with multiple modes of gameplay and an unexpectedly sophisticated control scheme. More to the point, developer Nimbly Games is now offering it completely free.
It offers multiple free-for-all and team-based gameplay modes, Call of Duty-style perks, a variety of power-ups, and a throttle-based flight model complete with stalls. And did I mention it's free? Because it is.
Altitude is available on Steam, or DRM-free for Windows, Linux and Mac from AltitudeGame.com.
