Fortnite - playground become invisible?

How can I become invisible in Spielwiese.

My friend always trolls me with such an invisible trick

Can you please tell me how it works?

Ask your friend. I've never heard of this feature and have played Fortnite since s2. Maybe it was somehow new, who knows. 1v1s I play in Creative Mode.

Here. He explains it in the video too

You have to respawn if you play a shadow game but really only if you do not have the mind you have to record the stone and respawn directly is very hard but it works

Hope could help you

Yes, ok 1vs1

-and thank you

Are there any shadow stones left in Spielwiese?

No
