24 Hidden Gems Launching on Steam This Week (15th–21st of September)

Every week, there are hundreds of games coming out on Steam, and with so many titles begging for your attention, it's difficult for some indies to get the limelight. For that reason, we began our weekly series for upcoming titles, where you can check out all of the best games coming out!

For our Hidden Gems entry, we have one criterion: anything below 1,000 Followers that we feel deserves to get more eyes on them. With that said, do bear in mind that these games might get delayed — we are working on information based on when this article was written.
