Hi,
Is there some tutorial or a good explanation how to create a main menu when the game starts up and how you could create different game modes like story mode, survival mode?
Main Manu usually need to be placed in so called Entry level which is loaded when you start the game, you can set it up in project settings, Maps and Modes… you know how to do UI right? there many ways and it would be long explanation needed 
You create diffrent modes by extending GameMode class, best is to create base class which have common to all modes gameplay support and then extend from that mode, here example from UDK how CTF mode is set up in UT example (GameMode was called GameInfo in older versions of UE)

Then you can use “Open Level” node with “game=GameMode” (not sure if thats correct) in options input with gamemode being name of your game mode
thanks , but i have some other questions, can i for example have 5 levels and change it from order? so from level 1,2,3,4,5 → 3,5,2,1,3?
and can everything done by blueprints?
Hmmm maybe via level streaming, or game saving? So you could have global variables that does not reset
ok i will try and sort it out, thanks for the help.
