Green Man Gaming is offering big discounts on the BioShock series. The original BioShock and the 2K Marin-made sequel, BioShock 2, are $5 each, while BioShock Infinite is down to $20.

The discounts don't extend to the recently released arena combat mode, Clash in the Clouds. Two more add-ons have been announced for BioShock Infinite, including a return trip to Rapture in Burial at Sea and a following episode where players will assume the role of Elizabeth.
