About Space Defense Special Force

Space Defense Special Force is a 2D shooter in which you pilot a spaceship through screens filled with enemies. You can move forward, backward, left and right, and customize your ship with different weapons, attributes and designs. The game has five modes, each with its own upgrade systems and challenges.

Game modes

  • Campaign Mode: After each mission, purchase improvements to make your spaceship stronger and more versatile.
  • Arcade Mode: Choose power-up cards to improve your abilities or recover health.
  • Invasion Mode: Collect upgrades and downgrades dropped by defeated enemy ships; downgrades can weaken your spaceship.
  • Survival Mode: Choose upgrades at the start, then fight to the end without upgrading again.
  • Frenetic Invasion Mode: Fight endless waves of enemies and increasingly difficult challenges, while collecting upgrades and downgrades.
