The Frozen Throne gives you even more of the story involving Prince Arthas, the elven Prince Kael’thas, the elf-turned-banshee Sylvanas Windrunner and a host of other characters. It brings the story up to a point just shy of where World of Warcraft takes off, and it does it all with the same style that we have come to expect from all Blizzard games.
The Frozen Throne also introduces new units and heroes such as the Blood Elf Spell Breaker and Dragonhawk Rider. An entirely new race, the Naga, has also been added. Working with Illidan Stormrage and Prince Kael’thas, the Naga are a force to be reckoned with. They include a whole host of units and buildings, all unique and as well-balanced as the other races.
As well as new heroes for each of the established races, The Frozen Throne introduces a system of neutral heroes, which can be purchased from a tavern (like mercenaries in Warcraft 3.) They include several very unique characters such as the Panderan Brewmaster and Goblin Tinker. Each neutral hero has a wide range of abilities that make them very powerful allies.
Lastly, The Frozen Throne gives us a mini campaign focused around a new Horde Hero, Rexxar. The campaign plays very much like an RPG, adds more lore to the world and helps set the stage for World of Warcraft quite well.
