Warcraft: Orcs & Humans is the first game in the Warcraft series developed by Blizzard Entertainment. The Orcish hordes are summoned through the dark portal to the peaceful human Kingdom of Azeroth. When the two races meet each other, a terrible war ensues. Only one race can dominate the land. Players can choose to play as either the Humans or the Orcs. There are 12 scenarios for each race with mostly a single objective: destroy the enemy. As with most RTS games of the same era, a lot of time is spent collecting resources and building structures to make/upgrade different types of units.
