Project Osiris

Project Osiris is a remake/reimagining of the Amiga FPS game Alien Breed 3D, using the GZDoom engine.

Alien Breed 3D was a valiant attempt at creating Doom but for the Amiga, a machine that really wasn't suited for such tasks. The pixels were huge and the viewport was tiny, but it was a technically impressive shooter considering the limitations. It even had some features over Doom - the water effects were amazing and it supported room-over-room and even texture-mapped 3D models. It was my first real experience of a proper 3D first person world in a video game so it was somewhat of a revelation to me. It may not be 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.

Features

• All 16 maps from the original game converted and adapted. 
  
• Overhauled graphics, textures and visual effects.
  
• New HUD, designed not to take up most of the screen this time!
  
• All 5 weapons from the original game, including new redrawn graphics - also an additional one that didn't make it into the original game, the knife.
  
• Various new items including body armor, small health packs, ammo drops and and map terminals have been added.
  
• All the original aliens are present and are angrier than ever with improved graphics and mechanics.
  
• Three difficulty levels, that do more than just increase monster counts.
  
• A new soundtrack by me under my musical name, Null Divisor, featuring 17 music tracks in total. Also lots of additional sound effects added!

This is not a 1:1 recreation of the original AB3D. Lot's of things are different either on purpose to improve the experience for a modern audience, or due to limitations of the engine or my coding ability.

I will continue to update the game as necessary. I also plan to add more maps from coverdisk demos of the game, but these have a different visual style and different enemies and weapons, so they will take some more time to finish. Look out for these in the future!

Thanks to Rayman the Hedgehog, Ozymandias81, Kinsie and DrPyspy for helping me out and/or letting me use stuff they made! Also HUGE shoutouts to John Girvin, whose work on extracting the original AB3D maps was basically vital for this project not to take a million years. There are further credits given inside the .ipk3 and/or during the end credits roll of the game.

This is my first Doom engine project and the first time I've released a big project to the world in general. Aside from the awesome help I've gotten this is mostly a solo effort by me, and I'm not a pro at game design or anything like that, so please bear with me if you have any problems!
