3-D Aggressor

The player’s task is to use the crosshairs to shoot down the alien, which is absorbing the energy needed to defend the planet. An alien is killed after being hit four times, and another one appears in its place. The energy level does not increase during the game, and the game continues until the energy is completely depleted. It is also worth remembering that each shot consumes some of the player’s energy, so the player must aim to land accurate hits.
