The incredibly underrated Ghostrunner is free for PC via Epic Games Store, but the offer is extremely limited, and interested players need to run to ensure they can claim it. Ghostrunner is a 3D action platformer game released in 2020. The title was developed by One More Level and Slipgate Ironworks and published by 505 Games and All in! Games. The main goal of the game is to traverse through its several levels using platforming skills and survive combats that revolve around the one-hit KO mechanic. This means that if the player is hit, they have to restart that phase.
