BATTLE: PARTS & POWER is a 2D idle auto battler about engineering the machines that fight for you. Build robot production lines, create a distinct blueprint for each factory, and defend your headquarters against escalating waves of hostile machines.

Build the Robot. Shape the Result.

Combat is automatic, but your decisions define every unit that enters the field. Choose a weapon, body design, skeleton frame, and modules for each blueprint. Balance damage, attack speed, range, movement, health, shields, regeneration, and build time—then watch the next robots enter the battlefield with your new configuration.

Manage Independent Factories

Build and upgrade up to five production lines—even while a battle is underway. Each factory has its own blueprint, module loadout, robot capacity, and active skill. Changes apply to future robots, allowing new designs to join the fight without altering units already on the field.

Turn Enemy Drops Into Better Builds

Enemies can drop weapons, designs, skeletons, modules, Assembly Cores, and active skills across multiple levels and rarities. Collect loot immediately or secure anything left on the field when the stage ends. Equip the parts you need, organize your inventory, and merge three pieces of the same level and rarity into a new part with a chance to climb one rarity tier.

Guide the Battle Without Micromanaging

Robots move, acquire targets, and fight on their own. Track incoming enemy groups, trigger factory-bound active skills at decisive moments, and adapt your production while the waves continue. Your preparation sets the plan; your timing can still change the outcome.

Push, Repeat, or Recover

Fight through 100 stages filled with enemy waves, minibosses, and stage bosses. Use Auto Stage modes to repeat a stable sector, step down after a defeat, or push forward one stage at a time. Factory levels, blueprints, inventory, and unlocked progress persist between attempts.
