What playing Halley Wars is like

Shoot 'em ups (shmups) put you in a ship facing waves of enemies and bullets. Runs are short and intense, and the goal is to survive, collect power-ups and push your high score.

Tip for newcomers: Focus on your ship's small hitbox rather than the flood of bullets, and learn which power-ups suit each stage. Most shmups are designed to be replayed many times.
