I was once trapped on a warehouse in Battlefield 2 with a helicopter trying to wait me out.
Other players kept swarming the place, and I knew if I stayed, I'd be overrun.
So I decided to bolt, even though all I had was a pistol and a sniper rifle.
Sniper rifle in hand, I flew out of the warehouse, and head shot the pilot in flight, without aiming, on the run, through an obscured windshield, at about 200 meters.
It was before everyone could replay their accomplishments.
Alas!
Second event, same Battlefield 2 game.
I saw a multi-player squad moving in formation come around a Boulder.
I was too close to aim, so I rushed them. About 8 players.
I knifed the 1st. Then the second. Was waiting yo get shot down at any second, just trying to get as many as I could.
I knifed the whole squad. If you've played, you know how long the stab mechanic takes. I thought I'd get 2 or maybe 3 before getting leveled.
To this day, I have no idea how no one could draw a bead before I killed them all.
