Build robot squads, besiege the enemy factory. 200 levels, offline, no login.
Scrap in. Robots out. Tear down the enemy factory before it tears down yours.
Gearline: Factory War is a fast, one-lane strategy battle. Your factory produces scrap, you turn scrap into robots, and your squad marches out to fight — then besieges the enemy wall until it falls. Enemies leave their factory in organised waves, so every level is a real fight, not a walk-over.
WHAT YOU DO
• Build a squad of 4 from 9 robots: Worker, Bolt, Heavy, Laser, Medic, Guardian, Mortar, Breacher and Commander — each with its own role (tank, healer, artillery, siege-breaker, buffer).
• Play 200 levels across 8 story sectors, with a boss battle every 25th level.
• Spend coins on 10 permanent upgrades — production speed, damage, armor, turret and per-robot masteries.
• Evolve your robots into Mk II and Mk III versions as you push deeper.
• Call in boosters mid-battle: Scrap Surge, Repair and Overdrive.
BUILT FOR SHORT SESSIONS
• Every win is rated 1–3 stars — replay levels to perfect them.
• Daily reward streak, rotating daily missions, 22 trophies, offline production that pays you while you are away, and a daily supply spin.
• Five robot skin tiers, each one hits a little harder.
• Even a defeat pays salvage coins, so you always move forward.
• No login, no account. Plays offline.
• English, Türkçe and Español.
FAIR AND OPTIONAL MONETIZATION
Gearline is free to play. Ads are optional bonuses or appear between battles; a one-time Premium purchase removes the between-battle ads (optional reward ads stay) and doubles offline production. Coin packs and a one-time Starter Pack are available but never required — every level can be beaten by playing.
