Keep The Ammo Flowing

Mine resources. Build the railway. Keep the gun firing.

The mining moon Calder has been overrun. As the last surviving engineer of a destroyed rail-defense platoon, you must bring a battered turret-and-furnace rig to Crown Bastion, the settlement guarding the evacuation route.

Keep the Ammo Flowing combines resource management, track building, and automated turret defense. Mine iron, return it to the furnace, and choose what to produce:

• Ammunition to hold back the swarm.

• Track to move closer to the exit.

• Repair supplies to keep the rig operational.

Your turret aims and fires automatically while you gather supplies, repair machinery, and extend the railway. Drive forward in travel mode, or deploy the braces and unleash heavy shells in siege mode.

Upgrade your rig between sectors, equip a support cart, and refine special minerals into ammunition that burns, freezes, pierces, or electrifies enemies.

Fight through 21 sectors spanning five regions and a final siege, from abandoned mines and crystal caverns to frozen passages and storm-battered uplands.

Keep the machinery running. Reach Crown Bastion. Keep the ammo flowing.
