Gameplay footage showed how the hero copes with harsh conditions and the main mechanics: players will use cars, fight enemies in different ways, and explore desert locations. Some of them are hubs where you can take a break from battles and meet friendly NPCs.
ExeKiller is described by the authors as a retro-futuristic western in a cyberpunk aesthetic. The events unfold in a dystopia after the catastrophic "Great Fire," which turned the Earth into a sun-scorched desert. The player controls an ExeKiller - a bounty hunter who catches criminals with valuable biochips controlled by the powerful corporation SOULS.
The gameplay emphasizes nonlinearity and the consequences of decisions, reminiscent of immersive sim classics like Deus Ex. You can act openly or stealthily, use the environment and dialogues, completely changing missions. The world is explored on foot and by flying transport, creating an atmosphere in the spirit of "Blade Runner" and "Mad Max."
