About the Game

Work of solo-developer Harry T, Neon Marble Rust is a Classic-style RTS that leans into the challenging aspects of beloved strategy games from the 90s. Build bases, manage resources, scout, strategize, tech-up, produce and control hordes of arena-bots. Play online or play a variety of single-player modes.

Neon Marble Rust is free-to-play, with practice modes and online play available in the base game. Newly released 'Super Ace' is a campaign-like game mode available as DLC.

- 3 Factions -

What started as friendly competitions between engineers eventually grew into a massive spectator sport. Originally, it was just duels, one custom-built robot fighting against another one. The spectacle grew as teams of arena-bots were pitted against each other, and it grew further when the robots became able to replicate. Custom-designed robots were replaced with strict paradigms, and by the turn of the 22nd century society was controlled by 3 cultish Houses: Neon, Marble, and Rust.

  • Emerged from the underground and established the first House. They were nearly ripped apart by a long-standing internal rivalry.

  • Modern designs & ancient inspirations. To achieve success their commanders must be proactive and dynamic.

  • Old machines from the forgotten age of consciousness. Their resourcefulness makes up for their inefficiencies.

- Classic RTS -

Base Building: Your bases will need resource drop-offs, army production, and static defense. Construct and defend additional expansions. Each faction has a different technology-tree and a fully unique roster.

Manage Resources: Just mining resources isn't enough, you'll need specialized buildings to make advanced resources. Each faction has additional exotic resources, which define their technology-tree.

Scout & Strategize: NMR is a Classic-RTS, which means your build-order is a big part of your strategy. Monitor your opponent so you can know when to expand, defend, or attack.

Control hordes of Arena-Bots: Units are produced in batches, typically of size 3 to 5, so you can make big armies. Some Arena-Bots can teleport, some fire skill-shots, others can install computer-viruses on enemy Arena-Bots.

- Dominate the Competition -

These arena-bots don't battle to conquer territory, they're here to win in the arena. Matches are 20 minutes long, and are decided by a Score. Each player's central buildings are their Cores, these are where players make their worker units. Destroy an enemy Core to earn 1 point.

- Variety of Game Modes -

Online Multiplayer: Play Quick-Match or make a Custom Room and invite your friends. Matches are all 1v1, but you can watch as an observer.

Skirmish/Sandbox: Play a match against the AI, can enable cheats.

Practice: 6 different modes, each simplifies the game dramatically. Completing the challenges earns stars and unlocks other units.

Replays: You can save replays of your matches in the basic game modes (online, sandbox, skirmish)
