■ The Core Madness: 17 Tanks with "Abnormal Evolutionary Trees"

Destroy enemies to progress and unlock a diverse fleet of over 17 unique combat vehicles!
This isn't just about simple stat buffs—each tank line completely shifts the gameplay, controls, and tactical approach.

【TypeX Series (Orthodox Evolution)】
The ultimate balanced models with heavily upgraded movement speed, turning rate, and max HP.

【Light Series (Unorthodox Mobility)】
Built for speed-demons. Features the "Float" which glides with drift momentum, and the "Anchor User" which fires a grappling hook to violently pull itself across the battlefield for insane high-speed maneuvering.

【Tank Series (Ultra-Heavy Firepower)】
Sacrifices speed for sheer destruction. Features the "Baccus" with wide-spread chaotic fire, and the "Ice Golem" which completely abandons ranged weapons to pulverize approaching enemies with devastating close-quarters punches.

【Eco Series (Green Technology)】
Specializes in high efficiency. Features the "Eco Recover" which automatically heals HP when your turbo gauge is full, and the ultimate tech masterpiece "Eco Ultima," capable of erasing every single bullet on the screen when activating Turbo.

【Mage Series (AoE Annihilation)】
Deploys specialized projectiles, including lock-on homing missiles that bounce off targets, and the "Vampire" which drains life from enemies to restore your own HP.

*Every unlocked tank can be switched in real-time right on the battlefield with a simple tap!
