Hello!
A game called Pizza Hero will soon transition from free-to-play to paid.
If you claim a copy of the game before it becomes paid, you keep your copy free forever.
The deadline to get this game for free is unknown, but the offer ends “soon”.
You can read the dev’s announcement here: Pizza Hero - Get Pizza Hero Free Before It Becomes a Paid Game! - Steam News.
Pizza Hero is a unique shoot 'em up roguelike. The toppings you select effect your abilities. For example, pepperoni throws grenades while blue cheese creates a pungent perimeter.
Enjoy!
