Enjoy the classic broodwar game with improved mechanics, new units, upgrades, abilities, and lot of changes that will improve the gameplay and open new strategies and compositions to fight with.
This is still my favorite mod, introducing many of the mechanics of SC2 and some units as well, has nice upgrade, it all fits together very well adn I find it very balanced.
I really love all the features such as having a Barracks selected and just right click on an addon and it will fly over there and dock.
