How do I add UGameEngine subclass to my project?


I need to do what Epic’s ShooterGame example does and add my own UGameEngine subclass so that I can intercept listen server host shutdowns and provide orderly home travel for the other player. (Can’t find anything that works in Blueprints)

I’m sure I can copy their code and get what I need but I’m unsure how to actually add this to my project in the first place?

Do I just use the Editor wizard?
Would that add it to my project everywhere I need to, or do I need to manually do other things too?


EDIT: Found at least one more things to do, How to subclass and then use UGameEngine? - UE4 AnswerHub
