Guild Wars 2 uses a heavily modified version

Proprietary game engine developed for Guild Wars by ArenaNet. The modifications to the engine include real-time 3D environments, enhanced graphics and animations and the use of the Havok physics system. The developers say the engine now does justice to the game’s critically acclaimed concept art, and that concept art will be integrated into the way the story is told to the player.

Guild Wars 2 allows a player to create a character from a combination of five races and eight professions, the five races being the humans and charr, introduced inProphecies, the asura and norn, introduced in Eye of the North, and the Sylvari, a race exclusive to Guild Wars 2. The professions, three of which do not appear inGuild Wars, are divided into armour classes: “scholars” with light armour, “adventurers” with medium armour, and “soldiers” with heavy armour. There is no dedicated healing class as the developers felt that making it necessary for every party to have a healer was restrictive.
