Saucer Swarm

Saucer Swarm is a Battle and Duel mini-game in Mario Party 8.

Gameplay
The players find themselves on a small podium with a laser blaster on a meteor-like area; presumably the Moon. Several flying saucer-like aliens are trying to home in on the podium and attack; and so, the player must use their blasters to keep the aliens away. Whichever player shoots the most within the time limit wins. There is additionally a golden alien who simply floats around in the background. Shooting this saucer is worth two points.

Ending
The player who won performs a victory dance, and the other three soon find themselves abducted by the alien spaceship that apparently sent the saucer aliens. The winner then watches the spaceship fly off.
