Geneshift (Steam - Free to keep when you get it before 10 June)

If you missed this last time, it was free a few weeks ago, now is your chance to grab it.

Geneshift is a GTA2-inspired shooter that merges battle royale and roguelite mechanics. Shoot, loot and drive through an army of enemies as you level up your mutant powers and try to survive. Play singleplayer or ride shotgun with friends as you fire bazookas, plasma balls, spike traps and more!
