About Trainfort

Craft your mobile base

Harvest, craft, and build with tactile hand controls, turning raw materials into dwarven masterpieces that unlock new frontiers. Pack up your whole base—shrunk to fit in your bag—and hit the rails to chase adventure. In Trainfort, staying mobile isn’t just fun, it’s survival.

Explore , Gather , Upgrade

Journey through fields, deserts, and infested forests, building grand steam engines to conquer the wildstrains. Infested zones challenge you with toxic gas, deadly monsters, and time limits, but offer special structures and technologies. Resources dwindle if you stay put, so roll on, dwarf!

Work together

Venture into the world solo or band with three other dwarven pals for co-op chaos. Clean infested area during the day, fend off nightly zombie swarms. Shapes your legend in the wild wastes !

Hands-On, For Real

Your hands are the interface. From looting debris to slotting tools on your belt or fighting off a zombie with an axe, everything you do is physical. The result? A looting and crafting experience that feels grounded, intentional, and unlike anything else.
