So, I encountered my first Nuke Booster just now...
Derail, I was playing like normal until I realized this one guy was getting a lot of knife kills. I looked at the names and it was the same guy getting the kills, so I decided to head on over. I was using my SMG class with Marathon on it, which was lucky, since it takes forever to get around that map. As I was running over to the cabin on the side of the side of the map, the one with a little fenced off side area, I noticed it was the same place repeatedly. So I ran over and gunned the guy on the other team down to ruin his streak.
Unfortunately, he had a tactical insertion not too far away, so as I was attempting to leave I got shot down. I returned and stopped him again, and they changed spots to a waaaaaaaaaaay far back corner. The guy had his entire team guarding them and I couldn't get to them without getting gunned down from several angles, so the game ended with the nuke. He's appearing offline so I can't follow him and try to continue stopping him.
I dunno, I'm a bit pissed off about what happened. Just felt like sharing. =/
