Astro Barrier is an arcade shooter that was playable as a minigame in the now defunct MMO Club Penguin. The game consists of multiple targets that, once shot at, will freeze in place and block other bullets. The goal of the game is to hit every target on the screen with a limited amount of bullets per level.

This TAS by Randomno aims to complete all the secret levels in record time, these secret levels show up if the player waits long enough on certain screens. This movie also skips directly to level 10 and 30 to access the secret levels.
