Du musst Bäume hauen, um Holz zu erhalten.

English Translation

You have to punch trees to obtain wood.

‘Hauen’ means ‘to cut down, chop down’ when dealing with trees; ‘punch’ is not a good translation here.’

I seriously think that this might stem from a Minecraft instruction. Then, it’s legit.

Edit: looked it up, ok, Baum hauen is a thing. Yes, then maybe cut down.
