Mutation is not actually as the name implies. Mutation is a number of modes that can be played for a week only. An example of one of these modes is where the four survivors can only use chainsaws with unlimited gas 4 a whole campaign.

Yes but it requires you to buy the campaign "The Passing." I think it costs 560 Microsoft points.
