ev.io ist ein 3D FPS Spiel (First-Person Shooter), das stark inspiriert ist von Bungee-style Shooter games such as Halo and Destiny. Players can engage in private rounds with their friends and invitees only, or aim for the top rankings in public games. The player must move through a futuristic environment while collecting points to spend on weaponry and special abilities to enhance their in-game character. Special abilities include double jumps, faster sprints, and teleportation. The game also features multiple game modes, including deathmatch and team deathmatch competitions, elimination rounds, and many more additional game modes planned for release in the future.
