OpenBack Tanks, Military Bases, and Tank Mines

Deploy tanks from military bases, extend their range, damage hostile land, and stop them with tank mines.

Build and stack military bases

Military bases cost 200,000 gold first, 400,000 second, and 750,000 afterward. A completed base launches tanks, while valid stacked bases extend their driving range. Hover a base to inspect that radius.

Deploy a tank

Tanks cost 500,000 gold first, 750,000 second, and 1,000,000 afterward. Place one on a completed base, then select a reachable destination. The vehicle moves slowly and damages hostile ground along its route before its final self-destruct strike.

Stop tanks with mines

Tank mines cost 250,000 gold first, 350,000 second, and 500,000 afterward. Their first level covers the same radius as a defense post, and every stacked level adds 25% more range. When an enemy tank enters that radius, one mine level is consumed and the tank begins destruction before reaching the destination.

  • Cover likely approaches instead of scattering mines randomly.
  • Stacked mines can answer more than one vehicle.
  • Choose paths that cross valuable hostile territory.
  • Remember that slow movement gives defenders time to react.
