Assembly League

Assembly League is a robot-building and combat game where you design a robot from over 150 components, program its behavior and send it to fight opponents in an arena. You choose how to equip your robot and write its strategy, then watch the match: once it starts, you no longer control the robot, which follows only its programming.

Build your robot

Choose components to suit your strategy. Loading a robot with weapons can make it overheat during a match, so you need to balance the number of weapons with how you use them.

Program its strategy

You can write code in a simplified language based on Assembly, or use a code generator to create the code without writing Assembly yourself. A code wizard can help when you get stuck on the robot’s artificial intelligence logic. The robot brain includes complex functions for implementing strategies, so you do not need to know or do complex mathematics.

Compete in the league

You compete against robots created by players around the world. The league has divisions of five robots competing to move up in rank. You can challenge one opponent in a 1v1 match, take on a whole division in battles of up to six robots, or send your robot against the top five in any of the eight Ranking Categories.

Battle arenas

Matches take place in the Battle Arena, where you watch your programmed robot fight without further control. New arenas load automatically from the server, and the Battle Arena changes for all players every week.
