Z.I.O.N. is a first-person shooter set in a post-apocalyptic world under attack by robotic creatures. You play as an agent of the Z.I.O.N. groups, fighting to save the planet. The campaign’s threats range from small machines to huge robots, alongside zombies in underground areas, giving its action a mix of enemy types and settings.
Survival involves more than shooting: players must hide from powerful energy emissions and turn off generators as they work toward saving the world. The game also includes time-slowing and temporary invincibility features. Hidden stashes add another layer of discovery, with contents described as ranging from a music player and ammunition to Steam keys for other games.
After the main campaign, Z.I.O.N. offers Derby, a separate mode with a dramatic shift in scale: you control a huge robot and aim to destroy the others.
