The Coreship appears in Gradius: The Interstellar Assault.


100 times larger than the Vic Viper, the Coreship is a massive, mothership-sized version of a Big Core warship. It's first found when the player is captured shortly after the ruins section of Gradius: The Interstellar Assault. Rather that fighting the ship head-on, the player ends up being pulled into its interior. This becomes the second stage of the game.

Attack patterns

While the player never fights the Coreship head-on, it does tangle with the Coreship's reactor. The reactor never directly attacks the player, but is able to suck the player forward as varying speeds. There's also a pair of cannons mounted above and below itself (which can be destroyed) which fire three-way shots diagonally. Electrical panels line the ceiling and floor and create impassable walls of electricity when they discharge.
