Shoot 'Em Up Meets Incremental Progression

Incremental Space Defense Force League is a retro sci-fi shoot 'em up built around fast arcade combat and long-term upgrades. Dodge enemy fire, destroy hostile ships, collect data shards, and make your craft stronger between runs.

Seven Skill Trees

Spend your rewards across seven upgrade trees: Pilot, Chassis, Primary Weapons, Secondary Weapons, Engines, Shields, and Computer. Improve your movement, weapons, defenses, and support systems to shape each run around your favorite playstyle.

Hold the Line

Push deeper into battle, survive tougher enemy waves, and keep upgrading as the I.S.D.F.L. fights to defend the colony from the Worms.
