GOG's Summer Sale has begun. But there is more! There is more. As part of the sale, GOG is hosting demos of upcoming games, including Desperados III and Nightdive's System Shock remake. Available for download now.

Also available are the time-bending RPG Cris Tales, the cozy management sim Spiritfarer, the "reverse horror" stalk-em-up Carrion, the role-playing strategy Vagrus - The Riven Realms, the remake of Destroy All Humans!"

If you don't mind spending real money, there are sales where you can actually buy the games; GOG has added "Metro Exodus" and 2017's "Prey" to its DRM-free lineup, both at significant discounts. Prey is only $9.

Other publisher bundles featuring EA, Activision, Paradox, Devolver, and more, and through individual sales of more than 3,000 games, will help you enhance your library. The sale will run through June 15.
