Although there are at least four known versions of id Software's official thirty two player deathmatch arenas BASE32 and DEATH32 online, (DEATH32, DEATH32A, DEATH32B & DEATH32C) the differences between them are mostly very minor structural changes, bugfixes and compilation differences such as the inclusion of transparent liquid support and radiant lighting, so please refer to the original review for more information, which describes all versions and the differences between them in more detail.
