Zerograve (v1.0.0)

A hostile industrial station becomes a six-degree-of-freedom kill zone where every wall, ceiling, and ventilation shaft can become a flight path. Zerograve is a fast, single-player tunnel-flying FPS built around zero gravity, placing you in control of a nimble combat drone cutting through lockdown corridors packed with machines. Its mood sits somewhere between arcade shooter intensity and claustrophobic sci-fi horror: cramped metal tunnels suddenly open into lethal arenas, alarms blare, and lava or automated defenses turn movement into a survival problem. Reaching the station’s mainframe means fighting through 24 levels across five distinct biomes rather than simply following a straight line from checkpoint to checkpoint.

Combat revolves around constant momentum, precision aiming, and making full use of the environment’s lack of a fixed up or down. You carry two switchable weapon loadouts, each holding a primary and secondary gun, letting you rapidly adapt when a crowd of small bots, armored targets, or a boss fills the screen. Primary weapons provide unlimited firepower, while the stronger secondary options draw from a shared ammunition pool, creating useful pressure around when to unleash heavy damage. Enemy kills and pickups unlock additional gear and upgrades, allowing a run-and-gun build, a more explosive setup, or a drone tailored toward whatever weapons feel best. Controls support gamepads and remapping, while the always-active trichording system is designed to keep complex movement and inputs responsive.

The standout feature is how seriously it commits to true zero-gravity combat instead of treating flying as a temporary gimmick. Ambushes during lockdown sequences, environmental hazards, more than 20 enemy types, and four major bosses—including the sprawling Cybernoodle—keep the campaign from becoming a routine corridor crawl. Its clean, readable sci-fi presentation favors speed and mechanical clarity over cinematic storytelling, making every encounter feel like an arcade challenge to master. Players who enjoy the aerial freedom of Descent, the pressure of classic arena shooters, or demanding score-chasing action find plenty to like, though newcomers should expect a learning curve before full 3D movement feels natural.
