The Retribution Engine has been designed for first person action games on 3D accelerated PCs running Windows 9x/Me and NT4/2000/XP. It is capable of seamless transitions between indoor and outdoor environments. Indoor areas utilise a volume-based visibility system that removes the need for bsp processing. The outdoor areas are rendered using a quad-tree terrain engine with static level of detail control. The engine is open source (GPL license) and the included games are freeware.
