Battle Tank: Steel Assault

The Rusted Legion has swallowed the supply lines. One tank is left: Unit 07.
Mow down the swarm, salvage scrap to grow stronger, and break through seven fronts!

■ One finger to move, auto-aim to fight
Drag the left side to move, drag the right side to aim yourself. Let go, and the turret locks onto the nearest enemy on its own. A horde survival shooter that delivers even in a few minutes.

■ A new build every run
Pick 1 of 3 skills at every level-up: Homing Missile, Twin Mortar, Chain Arc, Flame Spread, Mine Layer, Orbit Saw, Ion Beam, Ally Drones. Raise a weapon to Lv5, add its matching passive, and it evolves.

■ 7 chapters, 35 operations, 7 bosses
Six objectives: Survive, Annihilate, Defend, Collect, Hunt and Breakthrough. From the Furnace Giant "Crimson Flame" to the Rail Cannon "Thunderbolt" and the Mother Origin, every boss fights its own way. Clear the campaign to open 15 Elite Ops, each with its own Variant.

■ Build your own tank
Six part slots (Main Gun, Turret, Armor, Engine, Tracks, Radar) in six grades from Common to Mythic. Upgrade parts, fuse three into a higher grade, and reforge random options with locks so a good roll is never lost. 12 hulls, each with its own play style: unlock them with Nameplate Shards dropped by bosses, and promote them with the spares.

■ Same tank, different strategy
Spend points across the Firepower, Armor, Salvage and Supply branches of the 147-node Tactical Circuit. A single keystone turns your tank into a rapid-fire gunner, a boss hunter or a self-repairing wall. One free respec every week.

■ Paint it your way
Change the Paint Job, Markings, Muzzle & Trail, Kill Effect and Track Marks. Every hull also has Tank Skins in four grades, Rare to Legend: themed armor with flowing lava or crawling lightning, and Legend skins bring their own sortie scene and voice lines. Looks never change stats.

■ Ranked 2v2 squad battles
Online 2v2 matches where everyone starts on the same standard tank. Shoot the mobs roaming the field for Debris, then pick Overhaul cards mid-match: push your Main Gun toward Firepower or Rapid Fire, or mount two sub-weapons from Homing Missile, Twin Mortar, Chain Arc, Orbit Saw and Ion Beam and level them up. First to 10 kills wins; climb the tiers and the leaderboard. Practice offline against AI anytime.

■ Grow even while you're away
Recon Patrols gather Gold and XP for up to 12 hours, and Daily Missions, the Weekly Check-in and Research keep you growing.

■ Voiced in English, Japanese and Korean
Briefings, radio calls and chapter narration are all voiced in your language. Switch languages anytime in Settings.
