Game Usage
The Scout is considered to be the worst unit in the game because of its high cost and low air-to-ground attack. It is also incredibly slow to begin with and the speed upgrade costs another 200 minerals and 200 vespene gas. With the much more cost efficient Corsair available, Scouts are only useful on island maps where late game air battles involve strong air units.
