 This commercial, open source conversion of QUAKE II was originally released for the Amiga with a recommended min. configuration of 68060 CPU or PPC plus HD and 3D gfx card. Reportedly, it also works on Pegasos and Efika computers under MorphOS, despite a native build not being specifically released for the platform.
 In 2002/03, publisher Hyperion released 68K and PPC updates of QUAKE II. Registered users of QUAKE II may download the updates from their website HERE.
The QUAKE II updates included the following improvements and bugfixes:
- several optimisations - a transparent QUAKE II console - an FPS counter for the GL renderer - save screenshots via the GL renderer as JPEGs - bugfixes (savegame code, GL renderer of the first update, GUI)
 In 2005, publisher Hyperion first released a native build of QUAKE II for AmigaOS 4.x. A substantially reworked AmigaOS 4.x update of QUAKE II, courtesy of Peter Gordon, was released in May 2010. Registered users of AmigaOS 4.x and QUAKE II may download it from their website HERE.
