The game keeps the asymmetric mutliplayer balance by giving the lone player special abilities and adding in random factors. Both sides won about an equal amount of times. Another example of asymmetric multiplayer is the PropHunt mod for Team Fortress 2. In it 6 on 6, but even though only one side has guns, it is still balanced. One team can turn into any object to hide, but can't attack at all. The hunter team only has a limited time to find them all. The ingenuity of the hiding side is tested and the eye of the hunter team is tested.
