Alien Onslaught

Enemy carriers rip through the upper sky in Alien Onslaught. Earth’s defenses are already under pressure, and each mission throws you into a different combat zone with military hardware built for a specific part of the invasion. Six combat missions shift the battle from anti-air interception to armored assaults and close-range firefights against acid-spitting aliens. The first clash puts you on air defense duty, tracking hostile craft before touchdown. Later fights move across the ground, where heavy armor, rapid shelling, and sustained gunfire decide whether the landing force spreads any farther.

How to play?

Wait for the targeting system to lock before firing homing missiles, or the salvo will miss fast-moving shuttles. In the lower-left radar area, watch the nearest contacts and line up your next shot before a new wave slips past. Switch to the tank when ground units roll in, then pound armored targets with shells that punch through plating. Behind cover, fire the heavy machine gun in bursts and back away from aliens that spit acid at mid-range.
