Precursor Campaign 3 player coop file

The first three StarCraft campaigns remade to be much more challenging and with 3 player coop support, balanced to make the AI a thougher opponent that won't be beaten easily.All maps have been changed more or less to make space and sense for 3 players, as well as for better enemy bases, while staying true to the design and feel of the original map. Even with 3 players the enemy AI will still put up a though fight, assuming they don't bring it to you first.
