About this game
Get ready for an intense and dynamic 2D shooter inspired by classics like Space Invaders and Galaga! In Space Defense Special Force, control your spaceship through a screen full of enemies, while customizing it with various weapons, attributes, and designs. Move freely in all directions – forward, backward, left, and right – and test your reflexes across different game modes.
In Campaign Mode, upgrade your spaceship after each mission by purchasing improvements that make it stronger and more versatile. In Arcade Mode, choose from power-up cards to enhance your abilities or recover health. Invasion Mode challenges you to collect upgrades and downgrades dropped by defeated enemy ships, but be careful! Picking up a downgrade can weaken your spaceship.
Survival Mode lets you choose upgrades at the start, but once you're done, you can't upgrade anymore – you must fight until the end. In Frenetic Invasion Mode, face endless waves of enemies and more difficult challenges, with even more upgrades and downgrades to collect.
Each mode offers a unique experience, full of action and strategy. Challenge yourself, customize your spaceship, and fight for survival!
