The Humble Bundle is a well known staple by now of indie games, regularly letting you pay what you want for unique and quirky titles.
The Humble guys also do weekly sales, which this week is composed of basically every Serious Sam game. The best bit? All the money going to the Devs will be used to develop Serious Sam 4...
It's unlikely that they'll be able to fund the game exclusively with that, so don't be surprised to see a Kickstarter appear soon. Still, at the very least it's been announced, which is something to celebrate if you like classic run and gun shooters.
If you want to pick up the entire Serious Sam series (assuming you don't own them already) you can check out the Humble Weekly sale here. If you're after Serious Sam 2 and 3, you'll have to pay over the average, but that's still only $4.24!
Don't forget you can also give as much of your payment as you like to Charity as well if you want to make a difference. What do you guys think Serious Sam 4 will be like, as Serious as the rest of the series? Do you think you'll pick it up when it releases? Tell us below!
