Bastion, one of 2011's most lauded critical darlings, is now available with Steamplay, allowing users to install on both PCs and Macs. Furthermore, the game is now also on sale for the piddling price of $5.99, which is 60% off the normal price of $14.99.
The base game isn't the only thing on sale though. The Bastion Soundtrack Edition (game + soundtrack) and the standalone soundtrack are both 60% off today as well ($9.98 and $3.99 respectively.)
Though, curiously, Bastion: Soundtrack Edition and Bastion: Original Soundtrack aren't listed as having Steamplay yet. They're listed as only being compatible with Windows, though it may be a temporary error.
