Every title in the sale goes for $4.99 apiece, with Red Dead Redemption, Max Payne 3 and Spec Ops: The Line included on its menu. You can also visit Rapture in both Bioshock games, Liberty City in Grand Theft Auto 4, or an alien-infested version of Mars in Red Faction Armageddon, which is set in the future but will probably be historically accurate eventually - if there's one thing that video games has taught us, it's that aliens are out there, just waiting for us to inspire their rage.
There are non-retail-sized experiences as well, like Lara Croft and the Guardian of Light, Datura and PS3 and Vita versions of Guacamelee!. Whatever you decide to download, you've got until 3p.m. Eastern on May 5 to make your purchases. If nothing we've mentioned has your interest, you can check out the sale's full list of deals at the PlayStation Blog.
