As a gem hunter, go find all the gems stolen by monsters. There is a time limit on each stage so be sure to collect all of them before the time runs out.
Enemies are approaching closer and soon they will reach your base. Stop them by strategically placing from defense armies to turret towers in their way.
Your base is under attack! Get your best chopper out there immediately and demolish every enemy unit on sight. Don't forget to build towers and repair damaged towers to help accomplish your mission.
Use towers to build a labyrinth from entrance to exit. Each tower can be upgraded 4 times. With each wave, enemies will become stronger, so use money you earned to upgrade reasonably.
Fight against humanoid military forces through 6 different worlds, command allied troops armed with powerful lasers and destructive rays, upgrade your weapons, unlock electric mines and homing missiles and destroy everything in your path.
