About the game
You’re the designer, engineer and architect, if you can imagine it you can create it! Construct robots of any shape or size from eight-legged spider bots to eerie UFO contraptions. Engineer each and every appendage with powerful visual programming letting you dictate the bots every move. When you’ve completed your masterpiece, open the world builder and craft the ultimate obstacle course to push your bot to its limit.
Imagination is more important than knowledge.
Alone or with fellow inventors, envision your design then make it a reality.
You can do anything you want. This is your world.
Create a world in which your bots will be challenged. Craft tracks for racing or complex obstacle courses that tease out all those lovely design flaws you didn’t know you had.
Alone we are drone; together we are drones.
Show off your designer skills first-hand with up to three friends. Build worlds together to challenge each other's bots in different obstacles courses and tracks. Or smash each other's creations into metallic pulp (more coming soon).
Who dares wins.
No friends? No problems. We’ve created a single-player mode with over 100 challenges to test your inventions.
Visualize the code.
Don’t panic, we don’t expect you to code in C# (we’re doing that). In fact, it’s entirely optional, but if you’re up to the challenge we’ve designed a powerful visual programming tool for you to enhance your creations.
Share, Share, Share.
Add (or take) from the thousands of already created bots and worlds hand-crafted by our dedicated fans from all over the globe.
There’s no creation without destruction.
If you want to test the limits of your construction, then drive it off a cliff. Or smash each other's creations into metallic pulp in the devastating Bot Brawls mode.
