AReyeP's First Add-on is a map set for shareware Wolfenstein. It was made by AReyeP in 1993 (map files date to May that year), but was only brought to wider attention via being released at the Wolfenstein 3D Dome on September 1, 2002.
Originally made for shareware Wolfenstein v1.0, the map set boasts impressive design for its age. Though Spear Resurrection was roughly a decade away at this time, there are still some traces of its mapping style via AReyeP's flair for realistic designs, guard placements and overall room layout of which there were few and far between in 1993.
AReyeP, believing the set to be lost, found it by chance on a backup disk in 2002. This is most likely the cause as to why no links or mentions have surfaced of the map set prior to September 1, 2002. On this date, it was posted on the Wolfenstein 3D Dome, dubbed AReyeP's Lost First Add-on.
