Broforce, Surgeon Simulator 2013 and Retro City Rampage, discounted by up to 85 percent.
Not only can you feel free to use the money you'll save on some sweet explosion-rockets, but you can feel good about yourself too, as 10 percent of the proceeds go to charity.
You might want to hurry though; like a red, white and blue firework in the night sky - this deal will only exist for a short while. At the time of writing, there are just more than three hours left.
