Creeper World 3 is what happens when cellular automata takes over a strategy simulation.
Instead of discreet units that attack your base, a fluid-like substance spreads over the terraformable terrain. Your base, your weapons, your strategy... you must adapt them all.

Creeper World 3 bends what it means to be a strategy title.
Quill18 of youtube fame said of Creeper World 3, "I find this game to be extremely, extremely addictive". Instead of heavily scripted A.I., players find themselves engaging an enemy with theoretically predictable behavior yet which is shockingly interesting to engage. Players can build fortifications and stick around forever. Players can go for domination, quick strategic kills, or amass huge stockpiles of resources. Some play for speed, others to create art. Tiny maps, large maps, five minute missions, five day missions... the simulation scales to handle all of these scenarios.

User generated content is critical and supported at multiple levels in Creeper World 3.
Dial up worlds using the DMD (Dial Map Device) and tweak dozens of constraints. Then, play and share the addresses via an on-line database. Create your own maps using the built-in map editor and upload and share on-line. Or, join with thousands of other players and peruse the databases of worlds created by others. Want to create a new weapon, a unit, an enemy, or an effect? Use the built in scripting language to create what you dream. Hundreds of engine commands are exposed and examples abound on the forums and grow daily. You can even take the built in story maps and make your own. In fact, all of the built in story missions were written using the built-in editor and the CRPL scripting language.

Some of the high level features are:
  • Thermodynamic/fluid physics based play.
  • Billions of total missions.
  • Story arc with insane and unique enemies.
  • Explore hundreds of star systems with thousands of worlds in Prospector missions.
  • Hundreds of hand crafted missions in the Alpha Sector.
  • Dial up your own mission worlds using the 'Dial Map Device' and share the address.
  • Create your own maps using the included map editor.
  • Play on maps of variable size, dimension, and shape.
  • Script your own enemies and effects using the built in scripting language.
  • Terraform the landscape during missions to take the higher ground.
  • Discover experimental weapons that devastate the enemy.
  • Share thousands of unique maps with an established, enthusiastic on-line community.
  • Features a unique, original, and awesome soundtrack.

Excellent game. I have spent many hours playing CW1 and saw CW3 for cheap during the summer sale. I bought several games during the sale but keep coming back to this one. I would gladly purchase CW1 if it became available on Steam. I have not tried CW2 but would be interested in that as well.

I have followed Knucklecracker since CW1, All 3 are great games. I am not the best player but his forum for custom maps is a great way to work past some of the tougher maps, Some are still to hard for me but hey that is part of the fun.

Knuckle Cracker, no need to rush, take your time. Do it properly, I think community can wait. :)

It's about time this got greenlit! I was already losing hope it would ever happen.
This game is amazing. It is. AMAZING.
Got it? Good. Now go to and buy it. You won't regret it. I sure didn't.

Creep floods all over the universe, but there is a hope, there is a greenlight of relay that may be connected to the resistance net to help fight creep enemy :)
