Additional textures have been added to denote teleporters, and doors that require switches to open (very handy on MAP11!) Dynamic lighting is used on many objects and some areas of the maps now have coloured lighting where appropriate. New textures and visual effects have been added. The maps have generally been given additional monsters, tweaked item placement and even some extra shortcuts and surprises, but they are also still close the originals, for better or worse in some cases.

Having seen a few other attempts at remaking this game not reach fruition, I thought I'd step up to the plate and have a go at it myself!Īll 16 maps from the original game converted and adapted. So, I decided my first major Doom engine project would be to recreate it and also, ideally, iron out some of the issues of the original. It may not be anywhere near as tightly designed as Doom (honestly some of maps are pretty bad), but I have a lot of nostalgia for it, and it has a place in my heart. It was my first real experience of a texture mapped first person world so it was somewhat of a revelation to me. It even had some features over Doom - the water effects were amazing and it supported 3D floors and even texture mapped models. The pixels were huge and the viewport was tiny, but it was a technically impressive 3D shooter considering the limitations. Project Osiris is a remake/reimagining of the Amiga FPS game Alien Breed 3D, using the GZDoom engine.Īlien Breed 3D was a valiant attempt at basically creating Doom but for the Amiga, a machine that really wasn't suited for such tasks. It’s built on improved Doom II engine, but doesn’t require you to own that game. Project Osiris - Alien Breed 3D for GZDoom is a standalone free game created by ArcturusDeluxe.
