About Gunmetal Rails Demo

Build a War Train. Survive the Wasteland.

Try Gunmetal Rails — 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.

What's in the Demo

  • 4 unique locomotives — each with a passive mechanic that changes how you play

  • 12 weapons across multiple rarity tiers — from rapid-fire miniguns to explosive launchers

  • 50 upgrade cards — locomotive buffs and per-cart enhancements with real trade-offs

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

  • 9 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?

The 4 Locomotives

🚂 Iron Horse — Balanced all-rounder. Hits harder with every cart you own.
👻 Phantom Express — Glass cannon. 15% dodge, 15% crit, light carts have no speed penalty. Can't equip heavy carts.
💀 War Rig — Slow tank. +5 armor, all weapons gain 10% explosion chance. Medium and heavy carts only.
🔧 Scrap Hauler — Economy engine. +30% gold, +1 shop card, 20% cheaper prices. -30% damage.

Your Train, Your Rules

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.
