Hey there!
A game called 3 out of 10: Season Two is free to keep forever. As long as you claim a copy of the game before the 15th April.
Short Game Description:
Caffeinated super-powers, sentient AIs, and rival game studios all stand in the way of Shovelworks studios as they struggle to finally make a game that scores better than “3 out of 10”. Will this be the Season that they finally do it?
If you do not have the first game of this series, 3 out of 10: Season One, you can get that free too by clicking here. Season One was previously a paid game which is now permanently free.
