Humble Weekly Sale
While the Serious Sam franchise is repeatedly discounted, I'm not sure I've come across a better deal than this Humble Weekly Sale. It's pay-what-you-want pricing for Serious Sam HD: The First Encounter, Serious Sam HD: The Second Encounter, Serious Sam: The Random Encounter, Serious Sam Double D, Serious Sam: Kamikaze Attack!, and Serious Sam Public Test 2.
Putting in more than $1 will award you Steam keys, while beating the average unlocks Serious Sam II and Serious Sam 3: BFE. Does anyone need this much Sam in their life? Well, yes -- of course! There's also the fact that this will "help contribute to the production of Croteam's next project" which is none other than Serious Sam 4. What, no subtitle?
Disclosure-bot: Just in case the editor neglected to mention it, we have zero control when deals start and end. Deals can sometimes be gone within minutes (please don't shoot the messenger). Trying deal links even hours after this article's time stamp may lead to self-punching, so maybe bookmark our video game deals if you're on the hunt. Also, it goes without saying, but some shopping links do directly support the author. If you've spotted any inaccuracy please let us know asap.
