Sector 27 is a mod for registered Wolfenstein, made by Fgkjrujkuejrn.
Initially released as a 7-level demo on February 9, 2001 with rudimentary changes and a few new graphics, it was updated and re-released on February 20. This version replaced and overwrote the original February 7 version.
On January 28, 2002 a new demo was released featuring exploding oil barrels, among other changes. This release featured 2 levels.
Finally, on February 22, 2002 a 10-level complete first episode was released. There were no further releases of Sector 27.
Mapping is generally of good quality, and coupled with the new, exciting features (exploding oil barrels were a rarity in 2002) the final version made for a pretty exciting play.
