Go back in time with this week’s Humble Weekly Sale.

While most people recognize Humble Bundle for their larger 14-day sales, the website offers a weekly bundle for the same concept of pay-what-you-want. This week features “Retro Shooters”: The Humble Weekly Sale carries through next Wednesday, and features Serious Sam HD: The First Encounter, Serious Sam HD: The Second Encounter, Shadow Warrior Classic Redux, and Duke Nukem 3D: Megaton Edition. By paying more than the average price, buyers will also receive Hard Reset: Extended Edition and System Shock 2. Each bundle purchase also includes a digital copy of each title’s soundtrack.

Every game in the Humble Weekly Sale: Retro Shooters bundle is available for Windows, Mac and Linux, and will be redeemable via Steam. If the Weekly Sale isn’t of any interest, Humble Indie Bundle 9 just started; featured titles include Trine 2: Complete Story, Mark of the Ninja, Eets Munchies Beta, Brutal Legend, and FTL: Faster Than Light and FEZ for those who pay more than the average.
