Your mission is to survive an endless battle across a vast, ever-changing battlefield. Destroy enemies, collect resources, and upgrade your tank into the ultimate war machine.

Controls
W, A, S, D — Tank movement.
Left mouse button or Space — Fire.
I — Open upgrade menu (Pause).
ESC — Pause / Main menu.

Combat Tactics & Terrain
The map is procedurally generated for every new game. Use the environment to your advantage:
— Brick walls: Destroyable by gunfire. Blast through them to open new paths or deny cover to enemies.
— Stone (Concrete): Indestructible. Provides perfect cover from enemy fire.
— Rivers: Tanks cannot cross water, but shells fly freely over it. Lure enemies to the riverbank and eliminate them from a safe distance.

Enemies
Hostiles attack in endless waves from all directions. The stronger your tank becomes, the more enemies join the hunt.
— Multiple classes: From weak and slow units to fast interceptors.
— Heavy tanks: Thick armor (requires multiple hits) and high firepower.
— Bosses: Extremely slow, but highly durable and rapid-firing.

Upgrades & Progression
To survive, you must continuously upgrade your tank using Upgrade Points.

How to earn points:
— Destroying enemies: Accumulate score points. First upgrade at 500 points, next at 1000, then every 1500 thereafter.
— Collecting Stars: Bonus stars occasionally appear near your tank.
— Note: A star remains on the ground for 15 seconds only — collect it in time.
— After collection, the next star spawns after 90 seconds.

Upgrade Menu (Press I):
Points can be freely reassigned at any time — adapt your strategy mid-battle:
— ARMOR: Increases tank durability. Allows surviving more hits.
— SPEED: Boosts movement and maneuverability.
— POWER: Increases damage per shot. Enables one-shot kills on armored targets.
— BULLET SPEED: Increases projectile velocity for better accuracy against moving enemies.

Additional Notes
— Tactical Reset: After exiting the pause or upgrade menu, your tank becomes invulnerable for 3 seconds. Use this window to assess threats if surrounded.
— Game Over: If your tank is destroyed, press Space to instantly restart a new battle.
