Center Core is the boss of stage 4 of Salamander and Life Force. It also appeared on stage 2 of the Famicom version. It was replaced by the Zelos Barrier in the ZX Spectrum version, and in the MSX version, it was the sub-boss of planet Eioneus. It is considered one of the more frustrating bosses in the games it appears in. Center Core X, a Biomechanical mutant that guards the Liver Zone, is a different sprite of the central core.

Attack Patterns

Center Core has four enemy generators on the ground and six turrets. It also has three cores, and three barriers per core. However, that's not what makes this boss so frustrating. This boss fires cores at you, which bounce around the room until they hit you. This wouldn't be so bad if it stopped generating them after a while, but it doesn't. Even the best players sometimes end up dying here. This was somewhat remedied on the Famicom and MSX versions, where the Center Core fires fewer cores. However, after you fight it in the MSX version, you have to fight Dead End right after that. The MSX version has four barriers per core, and it has higher health.
