I think it’s always nice to have such a topic in a forum since there are many giveaways and free promotions throughout a year, or maybe someone here has a steam code or the like he or she wants to give away? Post that here too.
Please, if someone posts a giveaway code, be nice and thank them if you claim it so they can edit their posts and others won’t waste their time trying to redeem the codes, that’s always annoying.
Okay I will start with some current free games
Epic Games Store
Diesel Brothers: Truck Building Simulator is currently free on EGS separate from the weekly free games
