Space Defender 3D
Rotate the base turret and blast endless descending drone waves.
Space Defender 3D
You are the turret on the base platform. Drones descend from every direction — aim with the mouse or arrow keys, shoot them down, and keep base health above zero through endless waves.
Move mouse over the scene to aim the turret • Purple drones take 3 hits and deal heavy damage
About Space Defender 3D
Space Defender 3D puts you in the turret seat of a lone base platform under a starfield. Blocky drones with glowing eyes spawn at long range in every direction and descend toward your base, wobbling as they fly. Your turret rotates a full 360 degrees with an adjustable barrel, and the only thing between the swarm and your 100 HP base is your aim.
Waves scale relentlessly: more drones, faster approaches, and — from wave 3 — purple armoured drones that soak three hits and deal heavy landing damage. Mouse aiming gives instant turret response with elevation control, while full keyboard controls (rotate, elevate, hold Space to fire) keep the game playable anywhere. Wave-clear bonuses reward clean defence, and the endless format means every run is a high-score attempt.
How to Play Space Defender 3D
Press Start — wave 1 drones spawn at long range in every direction.
Move the mouse over the scene to swing the turret; higher on screen raises the barrel.
Click or hold Space to fire glowing shots at the descending drones.
Red drones die in one hit (9 HP damage if they land); purple armoured drones take three hits (16 HP).
Clear every drone to finish the wave, score a 30-point bonus, and face a bigger, faster wave.
The base starts at 100 HP — when it reaches zero, the run ends.

Tips & Tricks
- 💡Kill the closest drone first, always — landing damage is what ends runs, not the drones still far away.
- 💡Lead moving drones slightly: shots are fast but not instant, and drones wobble as they descend.
- 💡Between waves, pre-aim toward the side you cleared last — new spawns favour no direction, so scan constantly.
Space Defender 3D — Frequently Asked Questions
Where do drones come from?+
They approach from random directions at long range, descending as they close in. Each one that reaches the base platform deals damage: 9 HP for a red drone, 16 HP for a purple armoured drone.
How do waves scale?+
Waves grow by two drones each time, drones get slightly faster, and from wave 3 some spawn with purple armour that takes three hits instead of one. Clearing a wave scores a 30-point bonus.
Can I aim with the mouse only?+
Yes — move the mouse over the scene to aim and click (or hold Space) to fire. Arrow keys or WASD also rotate the turret and adjust the barrel for keyboard-only play.
