Operation: Mutant Strike 3 is a mod for registered Wolfenstein, initiated by Majik Monkee and released under the Monkeeworks banner.
It was released in October 2011 and came out more than six years after the previous OMS mod.
10 levels are featured, and various mappers contributed. Majik Monkee made the opening level, with the remaining slots being made primarily by Ron van Rijen, plus Joshua Waight, Dean Horton and Thomas Weiling.
Many graphics have been changed, and the status bar has a new look in terms of the protagonist, Jill Hunter.
Music was lifted from various older games, such as Castlevania II, Metal Gear, Ninja Gaiden, Rygar and Chrono Trigger. Adam Biser contributed an original as well.
