Trouble Shooter/Battle Mania is a 1991 (and 1993 for the Japan only sequel) Shoot 'em Up on the Sega Genesis created by Vic Tokai.
Tropes related in the game:
- Action Girl: Madison and Crystal obviously fit the bill.
- Ambidextrous Sprite: Averted for Crystal in the sequel.
- Assist Character: This game's main gimmick is that you directly control Madison while Crystal follows her movements and can fire either forward or to the rear. She's also got Gameplay Ally Immortality. When Prince Eldon is rescued, he briefly becomes another assist character, only his movements are the opposite of the duo's.
- Dance Party Ending: Madison leads some NPCs in a sort of cheerleading dance as the staff roll begins. Then Blackball busts in.
- Dub Name Change: Mania Ohtorii and Maria Haneda were renamed to Madison and Crystal respectively for the English version of Trouble Shooter.
- Expository Gameplay Limitation: When Blackball crashes the ceremony upon Prince Eldon's rescue, Crystal had already left and Colonel Patch only has one blaster available, so Madison has to go through the final stage alone. It even extends as far as the final boss's first phase; Crystal finally returns to help finish the job.
- Expy: The "Trouble Shooters" of the title, Madison and Crystal, are based on "Trouble Consultants" Kei and Yuri from Dirty Pair.
- Hair-Contrast Duo: Madison is a dirty blonde and generally chipper and more girly, while Crystal has blue hair in cutscenes and is brunette in gameplay and is the more dour and serious of the two.
- Take That!: Both games have numerous strikes toward Nintendo. In the first game the Japanese version contains one where if you put-in a certain button action the Sega Logo Joke contains Madison stomping on Super Famicom.
