AUTOMATED MESSAGE /// On the Acid Planet, human beings have been all but wiped out. Hordes of bio-monsters run wild and have grown to colossal size. The largest of these beasts are known as Kaiju. You are a clone in the service of SCAV Corporation, welcome! You will conduct Kaiju salvage operations from our orbital station. Use your automatic defense systems, personal weaponry and drones to repel the swarm until the Kaiju arrives. Your only priority is the capture of the Kaiju cores. You will be re-cloned as required. Good luck! /// END MESSAGE

Construct towers and drone factories to defend your ship from the horde. Make use of the environment - strategic placement matters. Balance weaponry and defensive structures against developing your upgrades and economy.

Move your crew member to help your auto-shooting defenses fight back swarms of enemies. Between waves, meet the denizens of the desert in risk/reward encounters. Survive long enough and you'll face the massive boss Kaiju, each one with unique and devastating abilities.

Choose a powerful new ability or upgrade after every wave. Evolve your weapons and towers into strange new forms. Use recovered Kaiju cores to boost your abilities between runs.
