KILLBOX PROTOCOL: Bot Mayhem

KILLBOX PROTOCOL is a 3v3 battle robot brawler. Build a squad of three battle robots, draft the right modules and send them into the arena to wreck the enemy crew. The robot combat plays out on its own like an auto battler, but your taps decide every arena fight.

Three moves win every robot fight

- Slam: an enemy robot glows red as it winds up. Tap SLAM first and it gets COUNTERED.

- Dodge: a red lane means a big hit is coming. Drag your bot out of it.

- Surge: gold shields go up. Tap SURGE to break them.

Fall behind and OVERCLOCK lights up for the comeback. Knock enemy robots into the arena's ring-out pits for the KO.

Boss battles that fight back

Every chapter ends in a boss battle against a giant boss mech. Bosses change their attacks at Phase 2 and again in the Final phase, and later bosses demand new answers, from cracking a gold shell to breaking a combo. Before the fight, the shop shows the boss attack and marks the module that counters it.

Multiply your loot

Win a battle and load the chute. Drag to aim, release, and a torrent of cores pours through x2, x3, x4 and x5 gates into the bowl. Your first pour has a golden x10 gate. Watch an optional ad to double the haul.

Crack open Parts Crates

Beat a chapter boss and pick one of three Parts Crates, then watch the loot fly out. The odds are on the card: Scrap 60%, Rare 30%, Epic 10%. Bank it right away, or stake it on your next bout: a win doubles it, then triples it, and a loss drops it back to x1.

Build your robot squad

Jaw crawlers, drum spinners and tesla walker mechs: every battle bot has its own hull. Between bouts, draft one module: tesla coils, saws, plating, drones and more. Matching modules combine, like tesla coils that chain arcs between your robots. Reroll for a new hand or skip for a small bonus. Every chapter is a roguelite run: clear it, keep one card for the next, and spend alloys in the Garage on permanent robot upgrades.

KILLBOX SEASON

Every season brings 30 tiers of rewards, daily and weekly missions built on your Slam, Dodge and Surge moves, a free track and an optional Premium track with its own hull: Gold in Season 1, Violet in Season 2.

Ghost League, events and daily rewards

After chapter 2, climb the weekly Ghost League from Scrap to Apex in arena battles against recorded rival robot squads. Race rival bot crews in live events, take on the daily Boss Bounty and tune in to KILLBOX TV for daily rewards.

Album and Crew Chest

Collect every part, bot, foe and boss in the Parts & Bots Album and claim a reward for each finished set. On the league ladder, join a weekly crew: every crew win fills the shared Crew Chest, and each tier you reach pays out.

Lose, fix, win

A defeat shows what beat you. Tap Retry + Fix, or upgrade in the Garage, and run the arena battle back. Close the game mid-run and continue right where you left off.
