Bones Alert is a mod for registered Wolfenstein, made by Dark Wizzie. Visually, the mod comes across as more of a map set.
Coding changes are featured, and they include increased health and ammo and new demos.
Initially released as a 2-level demo in March 2007, an 8-level demo appeared on July 4, 2007 before the final version, dubbed v13.95, came out on New Year's Day 2008. Throughout the latter half of 2007 it was also stylized as a community project on the Haven forum.
New levels are featured in episodes 1 and 2.
