The prototype also comes with an executable that runs in software mode, but it only works if the computer is set to use 16-bit color. With nGlide installed, the gun's projectiles and various decals work properly, and the in-game decals stop flashing violently once a weapon fires at something. However, the OpenG元2.dll file must be kept inside the prototype's main folder in order to do so. The program emulates the 3DFX Voodoo Graphics feature, allowing the prototype's OpenGL mode to work without problems. The only way to make the OpenGL mode fully work (meaning not removing OpenGl32.dll) is to use an application named nGlide. This means that the game's OpenGL mode will not work until OpenG元2.dll is removed from the prototype's main folder. The Prototype's OpenGL mode doesn't work with modern systems that do not have a 3DFX Voodoo Graphics Card installed. It has the player slide up or down ladders without any special effects instead.Įxtra damage is not inflicted if the player hits a target in the head in this prototype. When going up a ladder, the screen will tilt left and right while playing pain sounds to simulate the motions one can make while climbing up a ladder. That means if you exit a map and then go back to it, all enemies and puzzles will be reset. The game does not save a map's state once you exit. This is changed in the final game so that the player can look straight up. The player cannot look all the way up in this prototype, like in Quake.
