$14 off BioShock PC

BioShock is a shooter unlike any you've ever played, loaded with weapons and tactics never seen. You'll have a complete arsenal at your disposal from simple revolvers to grenade launchers and chemical throwers, but you'll also be forced to genetically modify your DNA to create an even more deadly weapon: you. Injectable plasmids give you super human powers: blast electrical currents into water to electrocute multiple enemies, or freeze them solid and obliterate them with the swing of a wrench.

• Hack devices and systems, upgrade your weapons and craft new ammo variants.
• Biologically modify your body: send fire storming from your fingertips and unleash a swarm of killer hornets hatched from the veins in your arms.
• Explore an incredible and unique art deco world hidden deep under the ocean.
• Turn everything into a weapon: the environment, your body, fire and water, and even your worst enemies.
