Worms 2: Armageddon on Xbox -- Help.

When I played Worms on my brother’s PC 1997 I created my own games – number of opponents, weapons availability, and so on. It was great.

Now that I have Worms 2: Armageddon on Xbox 360 as an Arcade game, I seem to be unable to do that. The choices I have, if I remember correctly (can’t double check right now), is something like Quick Game, Campaign and Mission. But in neither of those can I choose number of opponents and so forth.

Is there perhaps someone out there who knows Worms 2: Armageddon on Xbox Arcade, who can help me?
