Take command of the air-defense system and protect a radar station from an alien invasion.
Your arsenal includes twin cannons, flak burst, guided missiles, a laser cannon, and an atomic charge. Intercept fast targets and hostile projectiles, use thermal vision during night attacks, purchase ammunition between battles, and unlock new equipment as the campaign progresses.
Clear 30 waves or enter Endurance mode, where the assault grows stronger over time. Accuracy, reaction speed, intercepted threats, and station integrity all contribute to your final score.
How to play
Aim with the mouse or by swiping. Fire with the left mouse button or the on-screen fire control. Select weapons with keys 1–5 or the HUD buttons.
Hold the right mouse button to zoom and press T to toggle WHOT thermal vision. Guided missiles lock only onto targets inside the square reticle. Flak Burst damages an area and is especially effective against groups and fast drones.
Shoot down hostile projectiles before they hit. Protect both your emplacement and the station, then spend supply points on ammunition between waves.
