A roguelite bullet hell where you build trains — that's right, TRAINS. Add carts, bolt on guns, stack upgrades, and see if you can survive. Playstyle? Up to you.
Gunmetal Rails
SteamGunmetal 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.
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.

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.

Gunmetal Rails is in active development. Here's what's planned:

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.
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.
