About — CelSector Wiki

CelSector Wiki is a player-written guide site for CelSector, the 2D sci-fi action game from YumamiSoft. It covers the six sectors in order, every boss encounter, the full weapon roster, the clothing and grab systems, and the achievement cleanup that follows the credits.

The site is built around one rule: a page should answer the question that made you open it. Sector pages are written room by room and call out the points where a branch closes behind you. Weapon pages separate the catalogue from the recommendation, so you can look up a gun without reading a tier argument. Completion pages list the exact conditions behind each Steam achievement instead of repeating the store description.

Facts are checked against the Steam build, the in-game menus, the developer's patch notes and recorded playthroughs. When a detail is version-dependent, the page says which build it was checked on. This is a fan project and is not affiliated with YumamiSoft.
