One of the earliest modders to make changes to the source code, Barry Christian released quite a few mods which were all heavily rooted in classic Wolfenstein 3D. Probably enjoyed mazes a bit too much tho'.
A fixture on the early modding scene, Barry Christian kept in touch and returned briefly in the late 2000's before making a sustained comeback in 2016.
Barry Christian runs the Wolfenstein 3D Vault which hosts quite a number of very interesting downloads. All hail the Vaultkeeper!
