As the name implies, MutDodgeJump is a mutator that brings back the UT2004's ability to jump in mid air during a dodge, also known as a DodgeJump.
The mutator also provides an option (bAllowMultiDodge) to allow the MultiDodge ability, this lets players perform another floor or wall dodge right away.
