My favorite was “Halloween” in Halo 2 multiplayer, kind of a knock off “hide-n-seek” but with a twist.

No shields, no radar, the only weapons were a sword and a pistol, and you only had one life. One player was “Michael Meyers”, that player had the sword and chased down everyone else. All the other players hid and only the last surviving player could try to take down Michael Meyers.

The twist was the music. In Halo 2, you could hear enemy team chatter through the tv speakers and it got louder as you got closer to the enemy. Using that, Michael Meyers would have the Halloween theme song playing so you knew when he was close but you didn’t know where he was. It was truly thrilling, you hear the music, you know he’s close, but not where, the music would get louder and louder as he approached….and then he would walk right by your hiding spot. Or, you’re walking around as the music builds so you know he’s close, you think you’re safe because you have an idea where he is, and suddenly he’s right behind you with a sword in your back.
