Can anyone think of any old real 3d shooters? I would like to work out if quake was the first game to use 3d sprites, and what other games from that time use them.

Any suggestions?

Wolfenstein 3D, Wolfenstein 3D - Spear of Destiny, Doom 1 + Doom 2. The most known.
Also:
Nightmare 3D,
Rise of the Triad,
Ken's Labyrinth (not that well known one),
Blake Stone - Aliens of Gold (good one, was almost competitior to Doom)
---------------
Heretic
Hexen
Hexen II
Heretic II
---------------
This 4 games above have continuing story and belong together

Dark Forces
Descent
Descent II

I guess, enough for now? ;)

Well the oldest 3D shooter I can think off is Platoon (for C64 - in the late 80's). In level two of the game you were moving around the undergroud system of tunels and enemy soldiesr were attacking you (but only this level was 3D - the rest of the game wasn't).

quake used 3d models didn't it?

FreeFredy I got to say that Doom don`t use 3D sprites.The only thing that is 3D in the game is the map.At least I played it like anyone in the planet. :D

agreed, even though i played the demo of doom, it definately had sketchy 3D

Don't forget Duke Nukem 3D on your list. ;)

Quake and I believe Hexen 2 had 3d models. I'd have to double check on Quake as well but I'm pretty sure.

I am pretty sure that Quake use skins. I am not sure skins can be considered as "3D models"...

When you are walking around them,they just keep turning in your position like some kind of picture...
