Couple years ago I set up a "Hide and Go Seek" game on Halo 2 LAN. (Effectively Oddball FFA, carrier is stealthed, and have to rack up 10 minutes of holding time.) Can't remember the name of the level (been a while) but it was the Map Pack level with the M.A.S.H. looking shed on the street, and that little alcove in the top part of the map. Obviously that alcove was my favorite hiding spot as my friends searched for me. Well, one friend quickly recognized my hiding spots, and decided to lay in wait. He switched to the SMG and sprayed the alcove, then turned to wait. As he turned, I darted in behind him and crouched down. When my timer was at the 9:30 mark, a spectator was looking at all of the different screens in the room, saw mine, and tapped my shoulder while saying, "Oh man!" The friend laying in wait immediately knew where I was, as I run screaming past him trying desperately to avoid the hoard for another 30 seconds.
