Sam has traveled through time and space, and now he's traveling across platforms. Serious Sam 3: BFE is now available for download on Mac.

If you already own the game through Steam, the Steamplay functionality – which lets you play select games on both Windows and PC – is also unlocked today. If you prefer to save money on games where exploding, screaming dudes run right at you, you'll be happy to learn that Serious Sam 3: BFE is also marked down to $13.60 on Steam until April 30.
