Steam has served as a digital game store on PC for many years, but managing test groups, demos and reviews has generally relied on a system of demos and key distribution that leaves plenty of holes for scammers and other bad actors. Now Valve has launched Steam Playtest, so that developers can invite people and control access directly via the Steam store page for their game. Valve writes that this isn’t meant to replace Early Access beta testing, and can even be used alongside it, but unlike Early Access, this feature is free to use for developers and customers and doesn’t support sales.
