For fans of old-school shooters like Duke Nukem, Quake, and Doom, Humble’s got a new Bundle that’s right up your alley. The Best of Boomer Shooters Penta Boom 5 bundle includes up to PC seven games, each one offering its own take on the signature high-speed pulse-pounding wall-to-wall action we’ve come to expect from this subgenre of shooters. Since this is a Humble Bundle, the pricing is a little tricky, but it can work in your favor. You choose how much you pay, and the more you pay, the more games your bundle includes–and the more money goes to charity. For this bundle, the charity cash goes to Oceana, a group dedicated to ocean conservation, preventing overfishing, and protecting threatened species. If you grab the full seven-game bundle, you’ll pay just $20, which saves you quite a bit compared to the deal’s $158 value.
