Not really a game, but...
Testing gear out for What Paintball Gear last winter in the gardens of PGI towers. The test was body armour - I was padded head to toe and Joe, 10 feet away, had to shoot me in various places to see how the padding worked. He took aim and managed to hit me on the one inch of my body that wasn't padded - side of my neck.
Freezing cold, old, hard paint, gun dialled at 295fps, no game adrenalin - hurt to ****.
And looked like a love bite.
