L.A. Meltdown, Lunar Apocalypse, Shrapnel City, and the Birth are all pretty good campaigns (Lunar Apocalypse was a little long winded for me but WAY better than the other tree campaigns).
Duke it out in D.C., Nuclear Winter, and Life's a Beach all miss the mark of the original campaigns by a wide margin. I only got lost like once in the Birth, while i was constantly lost and confused in the extra 3 campaigns because I just don't think they do a very good job of leading you. The levels are too big, which makes the playtime of the levels also too long.
