About This Game

The world is falling apart, and your family has been taken from you. The infected swarm the railroads, the plague spreads, and the only way forward is through fire and chaos. Keep the train moving, search for answers, and face the truth waiting at the end of the line.

Why settle for ordinary guns when you can craft pure chaos? Combine and evolve your projectiles—nest them within each other, fuse them into devastating combos, and fill the battlefield with nonstop explosions. The possibilities are endless, and so is the firepower!

Your train isn’t just a ride—it’s part of your build. Each railcar adds unique bonuses, from economy to battlefield control. Pick the right upgrades, mix the synergies, and fine-tune your setup to turn every fight in your favor.

Every run brings discoveries. Unlock weapons, find hidden mechanics, and expand your arsenal with each attempt. The more you play, the stronger—and wilder—your options become. Experiment, and push your limits with each new attempt—because no two runs are the same!
