Mac gamers need no longer miss out on BioShock Infinite's first DLC add-on, Clash in the Clouds, as it's available on Mac through Steam today.

Clash in the Clouds is a $5 arena combat mode where players take on waves of progressively more difficult enemies across four different maps. By completing challenges, players unlock additional concept art, Voxophones and Kinetoscopes.

BioShock Infinite launched earlier this year and has gone on to sell over four million copies.
