Mech Arena

MECH ARENA is a build-and-battle robot game. Assemble a mech from parts, forge your own weapons, set its AI, then watch it fight — in the campaign and against real players in the arena.

Build your machine

Six slots — chassis, torso, head, two arms, and a back mount. Every part pulls on two budgets: weight (your chassis's carry limit) and energy (your core's output).
Overload either and you pay for it — an overweight mech crawls and staggers, an over-powered one overheats mid-fight. Tune ability chips and a stack of AI behavior cards to decide how it thinks.

Forge your own weapons

The Forge is a free-assembly workbench: drag parts onto the grid, snap them together, and what you build is the weapon — its shape decides its stats. Longer means more range, bigger means heavier.
Roll for quality, name it, and mount it on your mech.

Then let it rip

Battles are fully automatic, deterministic 1v1 duels — you built the machine and the strategy, now you watch it play out.
Sweep enemies off their feet, taunt them into a rage, play dead and counterattack. The flashiest wins make the best highlights.
