Halls of Stonehenge is the first project released by Majik Monkee. It was released on November 1, 2003.
21 levels are featured, made by both Majik Monkee as well as ack. Graphics have been completely changed, and the vibe of the mod is very creepy and subterranean. New sounds also make for a very atmospheric play.
The code changes include textured floors and ceilings, message screens and a new weapon.
It is still only available in DOS.
