Ready for a (bio)shockingly good bargain? The latest offering at Gamezebo Deals is a Mac-only treat for those looking to dive head first into the depths of Rapture.

For $15.99, you can get the Mac versions of Bioshock and Bioshock 2 – two of the most popular games of the last 10 years. A healthy dose of role-playing elements infused these first-person shooters with a fresh sense of gameplay, and the storytelling was simply out of (or perhaps, under) this world.

Don’t wait too long – the last boat to Rapture leaves soon! Click here to get in on this great Mac-exclusive offer.
