A swarm of alien ships drops out of warp, lining up to smash your home station, and all you've got is a single laser turet and a dream. So you place that turret, watch it auto-fire, and start banking the scrap from every kill. Space Defense Idle is a strategy game where you build a wall of turets, missile pods, and shield generators, then let them grind down endless waves while you reinvest the lot into bigger guns. You click to drop new defenses, click again to upgrade their damage and fire rate, and pick which threat to prioritize as bosses crash the party. Ready to turn one sad little laser into a galaxy-eating fortress?
How to Play & Controls
- Place turets and defenses with Mouse click on open slots.
- Buy upgrades or level a unit with Click / Space.
- Switch attack modes or target priority with the 1-9 keys.
Tips & Tricks
- Rush your scrap-income upgrade first so every later wave funds itself.
- Stack splash turrets near the entry lane to melt clustered swarm enemies fast.
- Hold a reserve of resources before each boss wave so you can panic-upgrade your shields.
