Your mission in Save from Aliens III is to save the city from an alien invasion. Only your fighter ship will stand guard and defend. You cannot fly towards, but only move in a horizontal plane. Intercept unidentified objects flying from above that look like ships. It is necessary to shoot at them until a fiery cloud of explosion appears. Some enemy flying saucer-like ships can reach buildings faster than others. Shoot them first and then destroy the rest. The attacks will intensify, your task is to prevent the buildings behind you from being destroyed in Save from Aliens III.
