About N.E.O.N. HORIZON
The mission was never meant to return.
Build impossible ships. Adapt your build. Survive the journey. Reach Horizon.
Choose your weapons, relics, upgrades, and route — then combine them into a build powerful enough to survive elite enemies and multi-phase bosses.

More than a century ago, humanity initiated Project N.E.O.N. — the Navigational Expedition for Observable Nothingness.
At the heart of the project was NH-017, an autonomous research station governed by artificial intelligence. It spent seventy-one years crossing interstellar space before reaching Horizon.
What it found there changed the mission forever.
Now, cut off from Earth, NH-017 remotely commands its remaining combat vessels, sending them through hostile space in an attempt to reach Horizon and transmit a warning home.

Beyond the first act, the expedition continues into increasingly dangerous territory. Build and evolve your own ships, combine weapons, systems, relics, and powerful synergies, choose your route, and uncover what NH-017 discovered beyond Horizon.
• Build your own ships from the hull up — shape their structure, install weapons and systems, and create designs built around your playstyle.
• Fight through fast-paced sci-fi roguelite battles against escalating enemy forces, elite threats, and multi-phase bosses.
• Combine weapons, upgrades, relics, and powerful synergies to create new builds and strategies every run.
• Choose your route between battles, balancing risk and reward through branching paths, events, shops, and dangerous encounters.
• Adapt your ship as the expedition evolves, turning new systems, technologies, and discoveries into new possibilities.
• Face randomized rewards, encounters, and build paths that make every expedition different.
• Reach Horizon and uncover what NH-017 discovered there — and the fate of Project N.E.O.N.
