ArenaNet Guild Wars

ArenaNet's Guild Wars engine is a proprietary game engine that was developed for the Guild Wars online role-playing game (RPG) franchise. The engine was modified for Guild Wars 2, which was released in 2012. Guild Wars 2 uses a heavily modified Guild Wars game engine which includes support for true 3D environments, more detailed environments and models, better lighting and shadows, new animation and effects systems, plus new audio and cinematic engines. The game requires DirectX 11, with effect from Spring 2023. Guild Wars 2 utilises the Havok physics engine to provide ragdoll animation and destructible environments, as well as occlusion culling technology licensed from Umbra Software to optimise 3D object rendering.
