Highlights
45 parts
Chassis, wheels, treads, armour, weapons and more, in 10 categories that snap together.
Free building
Hinges, spin motors and pistons: a plate on a hinge is a flipper, a disc on a motor is a spinner.
Real damage
Hits dent the mesh, plates bend, broken parts fall off and the frame can be cut in two.
AI opponents
Aggressive, careful, flanker: profiles that read the arena and avoid the hazards.
A whole career
3 leagues, 12 events, rivals, trophies, a scrap economy, a shop and challenges.
Mobile ready
Floating thumb stick, weapon buttons and the safe area handled. Tested on Android.
About the pack
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#.
A whole game around it. A 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. The complete UI is built from code: menu, garage, shop, career, results with judges' scores, pause, settings and loading screens with fight cards.
Ready to use. Main Menu, Garage and Arena scenes, plus two demo scenes: a part showroom and an instant AI-vs-AI fight. A setup window checks your project and adds the scenes in one click. 23 EditMode tests and a full PDF guide (add a part, a weapon, an opponent, an arena).
All original. No third-party code or art: models from our own Blender scripts, textures from code, sounds synthesised at runtime. The UI fonts are free fonts under the SIL Open Font License (included). Online multiplayer is not included.

01
Build it
Parts snap to sockets and to mounts on other parts. Rotate, resize and mirror them with undo and redo, watch the live stats for weight class, mass, speed and power, then paint it: 3 finishes, 5 patterns, stickers and racing numbers.
02
Break it
Physics combat with flippers, spinners, hammers, saws and rams. Each part has its own health. Arena hazards — floor saws, a hammer, a floor flipper and a pit — punish careless driving.
03
Win
Win by knockout, pit, immobilisation or a judges' decision on points. Hit-stop, camera shake, sparks, smoke, debris and a crowd make every hit land. Press F2 and an AI drives your robot.

Questions
Is online multiplayer included?
No. The kit is single-player against AI (and AI vs AI in spectator mode). The code is structured so robots are driven by an input source, which is the place a network layer would plug in.
Can I ship a commercial game made with it?
Yes. That's what it's for. The store licence lets you ship games built on the kit; you just can't resell the kit's source files as an asset.
Does it run on phones?
Yes. It has touch controls (a floating thumb stick and weapon buttons), handles the safe area and is tested on Android. The iOS project builds too.
How do I add my own part?
Make a part definition (a ScriptableObject), point it at your model and set its sockets and stats. The PDF guide walks through a part, a weapon, an opponent and an arena step by step.
