Gunmetal Rails

Build a War Train. Survive the Wasteland.
Gunmetal Rails is a roguelite bullet hell where you build and arm a locomotive, cart by cart, weapon by weapon. Attach carts to your train, bolt guns into their slots, stack upgrades, and fight through waves of enemies that get nastier every round. How you build is how you survive.
Your Train, Your Rules
This isn't just stat-stacking. Your build is physical. Every weapon fires from its actual position on the cart. Every cart adds weight and slows you down. Every slot is a decision. Do you run three light carts with fast guns, or one heavy cart loaded with a legendary cannon? That's on you.

Features
Multiple unique locomotives — each with a passive mechanic that changes how you play

150+ upgrade cards across 6 tiers — locomotive buffs and per-cart enhancements with real trade-offs

Dozens of weapons across multiple rarity tiers — from rapid-fire miniguns to explosive launchers

3 cart types — Light (2 slots), Medium (4 slots), Heavy (8 slots)

Varied enemy types — including healers, bombers, stealth units, and bosses every 5 waves

Drag-and-drop cart management — slot weapons, reorder carts, apply upgrades between waves

Endless wave survival — how far can your build take you?

Early Access Roadmap
Gunmetal Rails is in active development. Here's what's planned:
More weapons, enemies, and bosses

More locomotives with wilder mechanics

Hand-drawn artwork replacing all placeholder visuals

Co-op multiplayer (2-4 players)

Steam achievements and cloud saves

Community-driven balance and content — your feedback shapes the game

Pricing Promise
The price will always remain the same. No price hikes at launch, no "early supporter" tax in reverse. If you buy in Early Access, you're getting the full game at the same price as everyone else. Early supporters just get more time with it.
Built With the Community
Gunmetal Rails is a solo-dev project, and the survivors-like genre thrives on variety and balance. Early Access isn't just about funding — it's about building the game with the people playing it. What weapons feel good? What builds are broken? What do you want to see next? That feedback drives development. Community will guide the balancing of the game, to ensure its available to everyone to enjoy.
