Welcome to Warcraft 3 Extended Edition, a project with the goal of expanding the existing game by adding unused features from the campagin as well as by adding new content of the highest possible quality while trying to keep the game as balanced as it can be.
Humans have received a few additions, most notable ones are the Captain, Gyrocopters and the Holy Plating upgrade.
The Captain is a strong melee fighter and support unit. He can, along with the Footmen, be upgraded with Holy Plating, which reduces incoming magic and spell damage by 20%. The upgrade itself is available upon upgrading to Keep and researching Defend.
Also the Captain has Defend and Command Aura, which gives nearby units 10% bonus damage.
Note: All abilities can and will be changed depending on feedback from the players.
