I personally like the balance of power that each player had. The single player could easily pcik off people when they went alone, which forced the three players to work together, creating a more difficult scenario for the single player. I have played other minigames with this idea, and I have thought about the balance in the game. The other game involveed slow motion, and the single player could move natural speed. The slow motion players had more powerful wepons that neutralized the single player, so working together was key.
