About this game
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.SURVIVE THE DESERT

Patch 0.82
Hi everyone! This is a small patch to fix a bug where Steam achievements for hotshot and freak difficulties weren't coming through. Sorry about that! Your victories will still be saved even if the achievement didn't trigger previously. Now in 0.82 getting a win on hotshot or freak will trigger any relevant achievements for that difficulty retroactively. Thanks for playing! If you're enjoying the game, please consider leaving a review. They help me a lot :) Cheers, AdamRead full article on Community Announcements (Adam Travers)Patch NotesOfficial
