Defending the intelligence in 2Forts, slaughtered somewhere between 4 and 5 billion scouts with my sentry, so I just wandered into the opponent's base (32 players match with both teams maxre out)took the intelligence, and walked back, didn't get shot once.
Oh, and swarming a friend of mine with 1300 rifleman squads in C&C3, that was so epic (One squad=8 people, and so 10400 riflemen can easily cover half of the largest 8-player map)
I was sniping with the M95 in BF2, shot a jet pilot, the jet then proceeded to fly straight into a teammate of mine standing on the deck of the hangar ship, it shouldn't be possible.
