About this game

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, hold your lane 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.

100 Prestige Level

Find rare Prism Orbs to unlock 100 prestige levels beyond the main skill trees. Each prestige choice pushes your craft further with powerful bonuses and dangerous tradeoffs as you work toward the ultimate goal: closing the Wormhole.
