can you change DIFFICULTY?

[Caine]

i started LEGENDARY :D but i start to find it struggling/annoying, is there a way to change the dificulty of the campaign or do i need to fully restart it? thx

Yeah you can play any level even individually on any difficulty, it will still count towards progression/completion.

If you mean in game than no you can't. You have to fully restart.

you have to restart what ever level you are on at the lower setting.

Go to the MISSIONS menu, select whichever level you're on, and choose a lower difficulty.
You'll have to restart from the start of that level.
