Got a bit of a funny story. My buddies and I meet up and still play this on Mondays. I had rolled a newer character to mess around with a Sniper build after getting a Melee guy up to about 80. I log into my lower level Sniper and start working around my house. A little later some shmuck comes along and starts fucking with my base. This has become a frequent occurrence lately if you're not sneaking (Keeps you off radar), so I temporarily log out so my base gets packed up and stays safe, then I wait for my buddies to let me know the guy moves on. I log back into their world to find someone else has put a house down in the same spot as my base. Turns out the 1st shmuck's buddy was trying to log in and my house was in his spot, so they were trying to run me off the land effectively.
Well, it turns out that while his first floor door is locked the second floor was not. I was able to use the Marsupial mutation to jump to the 2nd floor and get into his house, then lay down in his bed. This pisses the owner off something fierce, including the 1st shmuck who has returned. They start shooting me up of course, but because of the bed regeneration and the PVP damage reduction they can't put a dent in me. I eventually get out of bed after they relent for a bit, only to find they pick the bed up. Shooting resumes, but I keep moving between the two floors of the house and allowing regeneration and a handful of Stimpacks to keep me up. They bring a 3rd buddy into the mix and they still can't kill me. This goes on for an hour and a half! At this point my buddies and I are just laughin' and they're sending strongly worded messages in PSN. After awhile one of my buddies starts crawling through a nuclear silo with the intent of dropping a Nuke on them for shits and giggles. The other buddy starts lighting up their base with an explosive weapon (preNerf), and unfortunately that prompts the three of them to log out just before the Nuke gets dropped. In an effort to try and keep them there long enough and engaged in messages before the Nuke came I had started faking an apology to the house owner and was able to get him to accept my Friend Request, so the long game is to revenge Nuke him at a later time. Bottom line: don't fuck with my base.
It may seem like a colossal waste of time, but it was entertaining as hell watching them waste a shit ton of ammo and send pissed off messages.
