- Shoot-'em-up 2 Description (Rhythm Heaven Megamix)

Shoot-'Em-Up (シューティング), also known in Rhythm Heaven Megamix as Shoot-'em-up 2 (かえってきた シューティング), not to be confused with the sequel in Rhythm Heaven, is the 7th minigame in Rhythm Heaven and the 44th minigame in Rhythm Heaven Megamix. The player controls a Blastronaut in a spaceship who is on an important mission to stop the alien enemies from invading Earth. It's also a sequel of Shoot-'em-up in Rhythm Heaven Megamix. In Rhythm Heaven, it is also available as an Endless Game.

Gameplay
This game is played in first person view from the spaceship. A varying number of aliens will appear on the screen one by one in groups. All aliens have appeared when the music reaches the end of its chorus. The player must then repeat the number and time they appeared, relying on the rhythm of the music. If a beat is missed, that alien will escape.

Button Mode

 * A or D-Pad: Shoot

Simple Tap Mode

 * Tap: Shoot

Timing Notes

 * Hit: The alien is destroyed completely.
 * Barely: The alien is only disabled, not completely destroyed. A barely counts as a hit in Rhythm Heaven, but it counts as a miss in Rhythm Heaven Megamix.
 * Miss: The alien damages the player's spaceship.

Endless Game
This game is also present as an Endless Game, unlocked after earning 7 Medals. Gameplay is about the same as the non-endless version, but differences appear:
 * The player has a life bar which is depleted with every miss. The life bar will gradually refill after being depleted any amount.
 * Once the player has reached the end of the non-endless game, the last three enemies do not appear. Instead, it loops to the second wave of Shoot-'Em-Up 2.
 * The player receives points for each hit, which rise as consecutive enemies are defeated.
 * Defeating every enemy in a wave will award the player a perfect bonus.
 * The background changes every two waves.
 * The aliens will change if you go far enough.
 * Instead of alerting the player to incoming waves, the Shoot-'Em-Up Radio Lady will congratulate the player for reaching certain scores.
 * The music cue mutes every time when you reach the higher level.
 * If the player is hit with an empty life bar, the game ends.

Trivia

 * The green aliens that are seen in the background during the Endless version of the game are the Small Aliens from Spaceball without their spaceships.
 * In Rhythm Heaven, missing even a single alien will cost you Just OK.
 * In Megamix, the background in the epilogue screens from this game is taken straight from Wario Man's stage from WarioWare: Twisted released for the Game Boy Advance. Wario Ware Twisted Wario-Man Epilogue.png
 * The screen the lady appears on in Rhythm Heaven Megamix appears to resemble a Wii U Gamepad.
 * The way the aliens slowly crawl towards the bottom of the screen in the DS version may be a reference to the alien's movements in the arcade classic Space Invaders.
 * In Megamix, the aliens are fully grey, part of the spaceship is green, and the effects when the aliens pop up are green, thus making the game look more like the DS version of Shoot-'em-up 2.
