Tank Blitz

Tank Blitz is an original free browser top-down tank game built around a destructible grid. Each level generates a fresh 13×13 battlefield with brick walls, steel blocks, rivers, grass and a command core. Brick can be broken by cannon fire; steel stops normal shells unless a double-shot power-up is active; rivers block tanks but let shells pass; grass is driveable and hides tanks from view without changing collision. Enemies use three behaviors—random patrol, pressure toward the core, and pursuit of the player—so they can flank, break through walls and force you to reposition. Every fifth level adds an elite tank with more health and a faster cannon. Destroy all enemies to complete the level and bank a clear bonus, then continue into the next generated map.

How to play

• Move with the arrow keys or W A S D. Movement is grid-aligned and blocked by terrain, tanks and the core.
• Press Space or J to fire. The shell travels in the direction your turret is facing.
• Press P or the in-game pause button to pause. The Shell pause card can resume.
• On touch screens, use the movement stick at the bottom (or the right in landscape) and the Fire button.
• Protect the command core. Any shell that reaches the core ends the run, including a player shell fired into it.
• Add ?seed=YYYYMMDD to the page URL to replay the same level sequence for that day.

Scoring and power-ups

• Raider 100, Sprinter 200, Bulwark 300, Overseer elite 500.
• Clearing a level adds a bonus of 200 + 50 × level.
• Shield absorbs one hit; Speed boosts movement for 8 seconds; Double fires two shells and lets you break steel for 10 seconds.
• Repair rebuilds the brick guards beside the core; Bomb clears every active enemy and enemy shell.
• Best score and best level are saved through the Shell on this device.

Controls and accessibility

The battlefield is a focusable canvas with an accessible description. Every button has a name, touch targets are at least 44×44 pixels, and the game can be paused and restarted from the keyboard or the Shell toolbar. Level starts, elite arrivals, power-ups, base damage and game over are announced through a polite live region. The game honours prefers-reduced-motion by removing screen shake, flashes, particles and decorative loops while keeping the full game playable.

Privacy and original content

Tank Blitz runs inside a sandboxed iframe. It does not collect personal data, does not load analytics, advertising or social tracking scripts, and does not request consent itself. Only the best score and best level are sent through game:save for the Shell to store in this game's own local-storage namespace. If storage is unavailable, the run still works and the values stay in memory for the session. The game name, tanks, terrain, core, power-ups, pixel art, music and sound effects are original or generated in this repository; no third-party characters, audio, level layouts or trademarks are used.
