Had one toxic player when I was around level 6. He came along and destroyed my entire camp and then started pvp. He was level 20 so I had no option but to run or quit and join another server.
Took me another 2 hours of play to recover all the materials to rebuild my small camp.
That’s the only pvp i’ve come accross but you know the old saying ‘everywhere I go there’s always a bumhole’
Seems unfortunate that was your early game experience. You'll only be able to build your base out of wood or steel at the start until you unlock further plans, and luckily those are the two easiest resources to come across - scrap pretty much any weapon and you'll get wood and steel out of it. Also if you do find someone has destroyed part of it, you can use the repair all structures option on the camp item.
