Practise aiming and repositioning, then fire ahead of a moving target while leaving the satellite room to evade.

Controls

Use directional and satellite-movement actions to adjust aim or position. Use the firing action to attack.

Global Defense — About this game

The satellite and its aiming cursor have different jobs. Place shots ahead of moving targets while watching the satellite’s position, rather than steering directly toward every enemy. A target near the cursor can still be dangerous to the satellite, so check both areas of the screen. Shift to open space when an approach becomes crowded, then line up another shot. Balance aim and evasion instead of concentrating on only one of them.
