Blaster Master Wiki

Planetoid E-3 is a location in Blaster Master Zero 2. It is the third planetoid in Area E.

General Information[]

Planetoid E-3 is unlocked after obtaining Planetoid Map E-3 on Planet Stranga. Planetoid E-3 consists of two rooms. The first room only features the Landing Point. The second room features a boss fight against Cerbeboss; defeating it gives access to Access Key 4.

Unlike most planetoids, visiting this one is required in order to progress through the game. By visiting Planetoid E-3, the player can obtain Access Key 4. By obtaining Access Key 4, the player can then travel to Area F-1 and visit Planet Divido.
