Hellslave : Project Z-Treme
Frag like it's 1997! Fully 3d Sega Saturn first person shooter with 4 players multiplayer support!

It came along a long way since lats year. We always had the question what the Sega Saturn might have been able to do if it succeeded in the market and devs put a real effort to bring out the possibilities.
It is interesting that the draw distances are just huge, and some environment objects like columns seem to cast some pseudo-shadow on the opposite site of the light direction. Lighting doesnt appear baked as it changes by projective lights.
I wonder how he achieved effects like real time reflections. He is probably calling it "a reflection" but it could be just a polygon duplication?
Here is a list of the things it achieved:
-Complete deathmatch experience, including against humans or bots, with up to 8 players.
-Fully 3D engine, the Z-Treme Engine, expanding on the Sonic Z-Treme engine from 2018 - but almost everything was rewritten, so at this point it's not the same thing at all - which makes uses of both SH2 cpus, SCU DSP, VDP1 and VDP2.
-4 players splitscreen deathmatch!
-Gouraud shading lighting everywhere, with realtime lighting supporting up to 9 dynamic light sources per vertex.
-Fully 3D weapons and enemies with AI, animation and lighting - Even the flying body parts have realtime lighting applied to them!
-High res 64x64 textures (for the Saturn)
-Brand new original 3d rendering code, matrix, vertex transformation, lighting system, polygon creation, collision, AI, etc.
-Fully 3d engine using binary space partition (BSP) with a PVS+portals occlusion culling system : somewhat similar to the technology used in Quake on PC, but fully running on the Saturn!
-Real transparency : water, light flares, clouds, windows, etc.
-Realtime reflections.
-Realtime reflections + dynamic lighting + realtime transparency : Look at a window, and you might see yourself and the room you are in... and also see the outside world! Try that on the PS1!
-Volumetric fog (faked, but still...)
-Depth shading
-Way improved culling and low distortion (no more polygons disappearing in your face, no more polygons dancing in your face à la PS1).
-No draw distance limit : the engine doesn't even have a far plane for frustum culling!
-New and fully original matrix, vertex transformation, lighting calculation, polygon creation and polygon sorting code, mostly in C.
-High amount of particles and flying body parts everywhere.
-3d pad optimized. 4 players Mouse and keyboards supported! Just plug your mouses in the mutitap in port 2, while the gamepads or keyboards will go to the multitap in port 1.

This really shows saturn was truly under utilized in its retail life
