Barney 3D Alternate Version is a mod for shareware Wolfenstein. Essentially a v1.4 version of Barney 3D, the mod features glitches due to incompatibility between shareware Wolfenstein v1.0 and v1.4, making for a confusing gameplay.

Otherwise both Barneys are identical, and its release is most likely a mistake from the early days of modding and the sharing of these.
