Speed Brawl and Tharsis are free at Epic Games Store. The free game offers run until September 23 at 11 AM Eastern. Once you claim them, they’re yours to keep.
Speed Brawl is a “2D combat-racer about moving fast and hitting hard! Maintain your momentum, build combos, and unleash powerful moves. Find your own fighting style, and assemble the best team of brawlers ever seen. Then do it all again faster.”
Tharsis comes from indie developer Choice Provisions. It is described as “a turn-based space strategy game with dice and cannibalism.”
