You are a metal part. Stay in service, answer in 15 seconds, load your rivals, protect your team.
Points: every second online in service = 1 point (+25 % for each teammate online with you). Right answer = 10 + 2 per second left + streak bonus. Damage: wrong or late answer adds 0.1 to your Miner sum; at 1 you fracture: −50 points and 30 s out. Fight: tap a rival, send a load block (3 ⚡): they get 15 s; if they fail, +0.30 damage for them and +25 for you; if they block, you take 0.1. Cooperate: tap a teammate: shot-peen (2 ⚡, −0.25 damage) or weld a fractured one back (3 ⚡). Idle: 40 s without doing anything and the Corrosion Pit attacks you.
