Defend the futuristic city of NeoCov from bizarre alien insect invaders! Your mission is to intercept and eliminate the enemies before they reach the city center. Use the fire button to shoot down the alien threats, but there's a catch, you can only carry 7 shells at a time. To reload, descend into NeoCov city center. Drop down into NeoCov city centre to reload, beware however, whilst in the city you are unable to shoot.
