It's been in my Steam library for years, but I'm pretty sure I actually paid for my copy long ago lol. I was planning on making a second list of more free games sometime in the next couple days, but since there's a ton of great free shooters out there already like Call of Duty: Warzone, Apex Legends, Fortnite, and many others, I didn't want the list to be only shooters. This list I tried to showcase games that maybe aren't quiet as well known or that don't show up as often on other lists that I'd seen online.
Great suggestion though!
