Michael Meyers Mode is great.
It has to be a private match.
Here are the rules
1. 1 Person is designated Michael Meyers
2. The rest of the party is designated victims
3. You play a Free For All match with a 1 life limit, so if you die you are out.
4. The Michael Meyers can use his knife only to stab the victims
5. The Victims may use their flash, stun, or smoke grenades only to avoid the Michael Meyers
6. Nobody may have classes with Marathon, Lightweight, or Commando
7. Whoever survives the longest without getting killed is the Michael Meyers in the next round.
I play this game with 4 people all the time and it is fun. With 8 people it has to be a blast.
