Experience Funcom's revolutionary Real Combat engine, and fight mounted or on the ground. A new multi-point melee system allows the players to swing their weapons where they direct it, in real-time, going head-on against the formulaic nature of online RPG combat. The Real Combat engine also allow players to team up in battle formations and command both NPC's and other players in epic multiplayer battles, as well as giving you the chance to participate in massive sieges.
In the true and barbaric vision of Robert E. Howard, 'Age of Conan' promises to bring mature online players something dark, new and refreshing. This is no cartoony fairytale, 'Conan' is made by grown-ups, for grown-ups, giving online gamers the chance to unleash the ultimate havoc and fury.
