Traveling in parties, world exploration, character advancement - all were going to be integral parts of the game. What's unique about Warcraft III is that players will not only complete quests and interact with NPCs, but at the same time, they will have to devise strategic plans to defeat opponents. Much like Starcraft, each race will be inherently different and require different strategies to master, this time focusing on capabilities rather than brawn. Orcs tend to rely more on melee forms of combat. Humans, on the other hand, rely more on technology, armor and weapons.
Demons utilize spells and magic against their foes.
They can resurrect fallen units. Of course, players will be able to play each of the races in single-player as well as multiplayer. Besides having unique units, magical abilities and weapons of war, each race will have legendary heroes. For Warcraft III, the developers have given the heroes qualities and traits we have come to expect from heroes. For example, Heroes cannot only gain experience they can acquire special items, maintain an inventory and even grant special items to other units.
