Unfortunately I found out the hard way that the caverns are easily controlled.
Vehicles can run you over when you warp into the caverns. I logged on and was like cool the Amerish caverns are open, let's go check them out. Warped in and bam! I get gang rapped by TR camping the gate. All I could do was stand there helplessly as they ran me over and over again until I was dead. They controlled the whole cavern, so there was no were to go but back to the sanc.
Yea, my first time in the caverns since the release and I can't even look around. Never got a chance to check out any of the others. Maybe one of these days I'll make it past the gate and check out what I spent $30 on.
The weapons are fun, but I want to see the caverns.
