New Avalon II consists of two "RPG"-style maps. Its not technically a campaign but does contain that certain campaign "feel" to it (because it is a long, multi-layered scenario). It is unique to say the least. New Avalon II requires Starcraft Broodwar, version 1.05 or later. (100% Macintosh compatible) I suggest you complete Blizzard's Broodwar campaign before playing it.
