Steam's Free-to-Keep Promotion is one of the best sources for free PC games on the internet, especially because they are permanent additions to anyone's digital library, but it seems August might be a slower month. What makes it stand out, even compared to Steam's own Free Weekend promotions, is that each game can be downloaded and kept forever (via Steam at least) as long as it is claimed before a specific date. For August, as of this writing, there's only 1 game confirmed right now.
What's worth noting is that this confirmation comes from backend info via Steamdb, which isn't necessarily "official," but it is highly accurate. Not every Steam Free-to-Keep game appears via this backend data until it is added, but every game that appears on its upcoming list typically gets added eventually. As such, it's entirely possible and likely that more than one Steam FTK game promotion goes live in August, but given that previous months have had 3-7 listed by this point, it may indicate a slower month.
Right now, Steam users can claim Yet Another Zombie Defense HD via the FTK Promotion (until July 30).
