This update changes the mission setup so that the L4D1 set uses it's own mutation. In this case I feel this is the best method since it puts focus back on the L4D2 survivors for story purposes while still allowing you to use the first set if you want.

Other changes are noted below. Though each map has had something changed, this is considered a 'lite' update as there aren't any major changes.
