I just had 2 troll this subject ...
Here's the best way to play this game:
1- Do as shown in the picture
2- Wait for 5 mins untill someone shows up
3- Deploy a claymore in your back
After this, just lay down in ur bed and be patient. Someone will walk throw... and try not to miss...
You can also deploy a drone for a back massage and a tea service.
This is just meant to be fun... don't be mad at campers because not everyone can play the way you do.
