Modular Robot Builder & Combat Kit is a complete, playable robot-combat game you can make your own. Players build a robot in the garage, part by part, and take it into the arena against AI opponents. Wheels tear off, armour dents where it's hit, spinners throw robots across the floor. Everything is data you edit in the Inspector, and all of it is clean, commented C#.
The garage builder
45 parts in 10 categories: chassis, wheels and treads, batteries, cores, armour, weapons, structure, mechanisms, attachments and cosmetics
Parts snap to sockets and to mounts on other parts. Rotate, resize and mirror them, with undo and redo
Free building: a frame kit you shape cell by cell, plus hinges, spin motors, pistons and turntables. Put a plate on a hinge and you have a flipper. Put a disc on a motor and you have a spinner. The weapon's power comes from the physics of what you mounted
Control mapping: any key fires any weapon, with delays for chained moves and sensors that fire automatically
Live stats and rules: weight classes, build points, mass, speed and power, with clear warnings
Paint: colours, 3 finishes, 5 patterns, stickers, racing numbers
5 starter templates, plus share codes that copy a whole robot as one line of text
The fight
Physics combat: flippers, spinners, hammers, saws, rams and every home-made mechanism
Each part has its own health. Hits press dents into the mesh, damaged plates bend, broken parts fall off, and the frame can be cut in two
Self-righting, and robots that keep driving upside down
AI opponents with profiles (aggressive, careful, flanker…) that read the arena and avoid hazards
Arena hazards: floor saws, a hammer, a floor flipper, a pit
Win by knockout, pit, immobilisation, or a judges' decision on points
Spectator mode: press F2 and an AI drives your robot (watch two AIs test your new part)
Game feel: hit-stop, camera shake, sparks, smoke, debris, crowd, procedural sound
A whole game around it
Career with 3 leagues and 12 events: duels, short fuses, hazard nights, and gauntlets where damage carries between rounds. Rivals, trophies, a scrap economy, a shop and challenges
Complete UI built from code: menu, garage, shop, career, results with judges' scores, pause, settings, and loading screens with fight cards
Phones and tablets: a floating thumb stick, weapon buttons and the safe area handled. Tested on Android. Gamepad and keyboard work too
Save and load, 5 robot slots

AI disclosure: the package's C# code, and the scripts that build its models, were written with the help of an AI coding assistant. No AI image, texture, 3D-model or sound generators were used for the package contents. The two UI fonts (Barlow, Russo One) are third-party, under the SIL Open Font License; their licences are included and listed in Third-Party Notices.txt.
