How it plays

How does Thunder Force IV play?

The game uses a side-view perspective, with the fighter moving through horizontally scrolling stages. The objective is to survive each stage, destroy enemy formations and mechanical defenses, and defeat a large boss at the end.

Players can move freely around the play area, fire continuously, and change among collected weapons. The stage order is initially flexible, but completing stages leads to later areas and a final confrontation. Power-ups improve the fighter's firepower, while limited lives and intense enemy patterns make survival central to progression.

Plan your run

What is the best way to play Thunder Force IV?

Learn the opening seconds of each stage before attempting aggressive attacks. Keep the fighter moving, but avoid drifting into the edge of the screen where terrain and enemy fire can limit escape routes.

Choose weapons for the situation rather than holding one indefinitely. Wide shots help against formations, while focused weapons are more useful against bosses and armored targets. Memorize boss patterns and preserve strong weapons for their vulnerable phases.

Before you begin

What should you know before playing?

  1. 1

    Use the stage-order freedom to tackle difficult areas when your weapon set is better suited to them.

  2. 2

    Watch the terrain as carefully as the enemies; many hazards are dangerous even when the screen is otherwise clear.

  3. 3

    Do not waste powerful weapons on minor enemies when a safer standard attack is sufficient.
