If you're looking for a great game to play on your Mac, then you could do a lot worse than the first two games in the Bioshock series. And, right now, you can snag both with a whopping 60% off making each title just $7.99 in the Mac App Store until November 7.

The original Bioshock takes you to the undersea city of Rapture, a city plagued with the results of genetic engineering experiments and won awards for its intense first person shooter design. Bioshock 2 sees you return to Rapture years later with new challenges and characters, and both are must have titles for FPS fans.

Grab them both now at the Mac App Store links below.
