Progress through an endless sequence of arenas while preserving lives and energy.
Move through the obstacle grid and destroy every hostile unit. Walls block movement and projectiles.
Arrow keys or WASD: move and face
Space: fire
P: pause
Patrol □ units guard routes. Hunter ◇ units pursue you. Sniper ○ units move slowly but fire faster projectiles.
Destroy enemies, intercept hostile shots, collect bonus pickups, and preserve lives and energy for larger arena-clear bonuses.
Demo mode uses an immortal, unlimited-energy pilot and automatically advances through every designed and procedural arena, pausing briefly after each clear.
Presentation Mode hides the side controls and expands the playfield. The browser will also enter fullscreen when permitted. Press Escape to return.
A grid-based tactical arcade shooter inspired by the design language of early monochrome computer games.
