It's a good day for fans of ridiculous old-school shooters. The latest Humble Bundle weekly sale compiles a set of six FPS games from the genre's heyday, all for paying at least six bucks.
The set includes Serious Sam HD and The Second Encounter, Duke Nukem 3D: Megaton Edition, and Shadow Warrior at any price. Paying at least six bucks--which, come on--will also net you Hard Reset: Extended Edition and System Shock 2. All of the games are available on Windows via Steam, while Shadow Warrior and Duke are also on Mac and Linux, and System Shock is on Mac. If you've meant to catch up with some of them, now is a good time, before the weight of the fall release schedule crushes us all.
