So yesterday I got the quest to kill all the Van Graffs
I got Boone and an NCR soldier and ranger from the emergency radio, and headed off to freeside. Once I entered the gate I hired 3 mercenaires, then walked to the other gate and hired 2 more. So I had a total of 8 followers. It was like having a column of soldiers following me... I loved it (Too bad the mercs won't leave freeside). But anyways, I walked to the Silver Rush and killed the door guard.
Then I went inside. Within the first 10 seconds all the mercs were killed. Within the next minute the NCR ranger and soldier were killed. Boone survived and we successfully eliminated the Van Graffs.
Many caps were had.
