Blizzard's WarCraft 3 Frozen Throne system requirements list both the minimum and recommended system requirements for playing the WarCraft 3 expansion. The detailed specs include information on operating system requirements, CPU, memory, graphics, and more. WarCraft 3 Frozen Throne is over a dozen years old, so it's pretty safe to say that any Windows PC purchased in the last 8 years or so will have no trouble running the game. The requirements below are useful if you're running an older Windows XP or earlier PC. While the recommended WarCraft III Frozen Throne system requirements are quite low, if you're still unsure of your PC's system specs, CanYouRunIt includes the game in their database and allows you to compare your hardware to the published system requirements.

WarCraft III: The Frozen Throne is the only expansion pack released for WarCraft III: Reign of Chaos, the fantasy-based real-time strategy game and game world that eventually gave birth to World of WarCraft. The game was released in 2003 and added new races, new units for existing WC3 races, four new campaigns, and five new heroes. It also featured new buildings, naval units, and minor gameplay improvements/upgrades. In addition to the new units and buildings, some gameplay changes include a new weapon and armor system, with some weapons being more effective and having different armor than in the original WarCraft III Reign of Chaos game.

Like many real-time strategy games, WarCraft III The Frozen Throne has an economic and military aspect that players must manage and balance in order to be successful. In addition to the single-player campaigns, The Frozen Throne also supports player vs player multiplayer capabilities that include a number of different game modes such as free for all, random teams, and arranged teams in skirmish matches with up to eight players (4 vs 4).

WarCraft III The Frozen Throne also features a full-featured world editor that allows players to create and share their own games and maps. Some of these custom games have become very popular, and their success has spawned commercially produced games. These include titles such as Defense of the Ancients (Dota), Island Defense, and several Tower Defense-style games.
