Playing for a very long time?

Me and a few friends have agreed to play Fortnite for 12 hours. Does anyone have tips on how you can always provide maximum performance and not einpennt after a few hours

That's probably not, unless you want to zerficken the next 2 days

At your own risk.

Energy drinks and coffee. Of course it is not healthy but it is up to you. In addition a few power bars from the local supermarket for the small hunger. Then that fits

My goodness, 12 hours, pff. ^^ Sit down and play. Do not forget to drink enough and getting up every two or two minutes can't hurt either. But 12 hours is really nothing extraordinary.
