A Mutator is a built-in component to the game which adds features or change the game characteristics in the Unreal series. All of the multiplayer-based Unreal games have mutators, and some can be gametype-specific, such as “No Orbs” in UT3 's Warfare gametype. Many modifications can be toggled on/off with the use of mutators.

This is how I’m approaching Modular Game Mode Component Design for my games. In my opinion Mutators offer some powerful game play options and flexibility. They deserve a place in UE4 and UE5 and should not be forgotten. I’m curious if others are taking similar approach. Lets Discuss.
