About Tungsteel
Tungsteel is a single-player mech autobattler where each fight is part of a larger struggle for territory and resources. Assemble your squads, choose their targets, and advance across a turn-based map to capture the enemy base while defending your own.
Build squads that work together
Assemble squads of up to five mechs with complementary abilities. Combine heavy hitters with machines that protect teammates, repair damage, and weaken enemies. Unlock more advanced mech types and reassemble your squads at homebase to find combinations that work against the forces ahead.
Choose how your machines fight
Set targeting priorities for each mech type: concentrate fire, finish off damaged enemies, or go after the biggest guns. Watch your choices play out as mechs trade shots, apply target locks, corrode armor, and support their allies.
Fight for the supply lines
Capture sources of metal, electronics, and energy to fuel your army. Keep routes to your base open so captured locations generate resources and your squads can repair and resupply. Cut enemy connections to deny them the same advantages.
Keep your army running
Damage, depleted batteries, and spent ammunition carry over between battles. Salvage wreckage after victories and decide where your resources will do the most good: fresh mechs, repairs for survivors, or unlocking the next tier. Every advance must balance the opportunity ahead against the condition of the machines you send.
