Batsugun is a Bullet Hell Shoot 'Em Up made by Toaplan in 1993, and their final one as well before their bankruptcynote . You play as one of six fighter pilots of the Skull Hornets squadron, piloting amphibious planes to stop a global takeover operation by King Renoselva A. Gladebaran VII.
An Updated Re-release, Batsugun Special Version, was released in 1994, effectively serving as an Arrange Mode with many differences. Both versions of the game were ported to Sega Saturn in 1996, ported by Gazelle (one of Toaplan's child companies after they closed down) and published by Banpresto. Batsugun received another home port in 2022 as part of Sega's Astro City V microconsole. A port to the exA-Arcadia hardware platform, BATSUGUN EXA LABEL, is set to be unveiled at Japan Amusement Expo 2023.
Contains the following tropes:
- Antagonistic Offspring: Olisis R. Gradebaran, Player 2's pilot of the Type-C ship, is the son of King Renoselva and strongly opposes his father.
- Bullet Hell: This game is one of the first Shoot Em Ups to have a plentiful amount of bullets fired by the enemy, making it the Trope Maker.
- Defector from Decadence: Olisis, the pilot of Player 2's Type-C ship, is actually the son of the Revolutionary Army leader but abandoned his family and joined the government's army to stop his own father.
- Evolving Weapon: By destroying enemies, you're able to level up your ship, which upgrades your shot type. This happens twice, after which, filling the experience meter while at level 3 gives you an extra bomb stock instead. The Type-A ship gains missiles in Level 2, and the main Spread Shot begins swaying its side shots in Level 3. Type-B gains side-shots in Level 2, and gains a homing lightning beam in Level 3. Type-C gains side-options that shoot lasers in Level 2, and some of the projectiles spawned when the main shot's waves split home in Level 3.
- Golden Snitch: If playing for score, the majority of it will be obtained by utilizing a specific secret in the boss fight against Jupiter, the Stage 4 boss. You need to destroy all 5 of its spires and the two laser turrets. Jupiter then spawns turrets from where the laser turrets were. If you then bomb these turrets or shoot them down while your bomb is active, you gain a massive score bonus from all of the turrets you take down.
- Not in This for Your Revolution: Iceman, the pilot of Player 1's Type-C ship, is a mercenary who only joined the government army for the money.
- Previous Player-Character Cameo: Schneider, the pilot of Player 2's Type-A ship, is the main protagonist of Flying Shark.
- Jeego, the pilot of Player 1's Type-A ship, is revealed to be one of the protagonists of Out Zone in his ending.
- Roaring Rampage of Revenge: Beltiana, the pilot of Player 1's Type-B ship, seeks revenge for her sister's death.
- Spiritual Predecessor: Many of the aspects of the DonPachi series were set in place in this game. The Type-A and Type-B ships in Batsugun would become the Type-C and Type-A ships in DonPachi, and the idea of Bullet Hell started in Batsugun would be refined in DoDonPachi. Considering that much of Batsugun's staff, such as artist Junya Inoue and programmer Tsuneki Ikeda, would later work on the DonPachi series under Cave, Batsugun can be considered the bridge between the games of Toaplan and Cave.
