A real-time tower defense duel. Build the maze. Send the waves. Break their base.
Every match is you against another commander: defend your lane with towers while your own army of drones and tanks storms theirs.
Defend and attack at the same time
Both commanders build and send in the same rounds. Whoever loses all their lives first loses; if both hold until the last wave, the one with more lives left wins.
Stretch their path
Every Blocker you place redraws the route enemy units must take. The longer you make it, the longer your towers get to fire.
Ten kinds of tower
Machine guns, cannons, missiles, lasers, plasma, flamers, artillery and more. Each damage type is strong against some armour and weak against the rest.
Pick your attackers
Choose which units march into the enemy lane each wave. Mix armour types: a defence built against one kind of unit leaks the others.
Two armies, two ways to attack
Level up each army to unlock its stronger units, perks and towers. More armies are on the way.
Iron Hive
A swarm of combat drones. Fast, numerous and hard to pin down, with Drone Citadels that carry more drones into the fight.

- Persecutor Drone
- Sentinel Drone

Steel Legion
Armoured ground vehicles, from quick Scouts to Heavy Tanks, with battle-worn Veterans that take far more punishment.

Choose how you win
Your commander class shapes every match and has its own ranks to climb.
Engineer Outlast
Your base starts with 50% more lives, so a leak or two will not end the match while your maze grows. Best for long, patient games and recovering from a bad wave.
Military Pressure
Ranks come quickly, and every rank adds more units per wave and more income, so your attacks grow faster than the enemy can answer.
