Uncharted 2 is awesome for things like this.
Multiplayer > Plaza > Even 5-5 teams > middle of the match
Both teams control their own side of the map, and I'm in the center building taking the SAS shotgun spawn.
"What's that?!" I say, as I hear gunfire on the side of the building where the Grenade Launcher spawns.
I check the map, my team is on one side of the launcher, with the other team taking cover at the other side. I count 3 enemies there on the front lines.
I have the shotgun in hand, so I make my way to the OPPOSITE side of the center building, and take cover on the corner before I could have a clear shot on the enemy team, who was using their side of the building to put supressive fire on the Grenade Launcher spawn.
I wait. I wait. I wait. AND THEN I SEE MY OPENING, no one was looking at the area I came from, all focused on my team on the other side of the launcher spawn.
"GO, GO, GO!" I say, half-way to the group of 3 enemies!
I get up to the first one, none have noticed me, *BAM*, 1 shot shotgun kill, run to the next, still not being noticed, *BAM*, 2 down!
The last guy still has not seen me, focused on my teammates. I say "Screw the Shotgun!" and go up behind and give him a heaping helping of *STEALTH KILL*
The entire attack force, dead at my hand within 4 seconds. A triple kill along with a stealth kill. It was a good match.
