[2-1] Fully three-dimensional environment

Explore Quake's true 3D environments and 3D models with textures, allowing for complex levels and hidden deathmatch spots.

Quake's levels are rendered in true 3D, a significant departure from earlier designs. This allows for intricate level construction where elements can exist on multiple vertical planes, such as one player standing on another's head. This 3D system facilitates more complex and entertaining level designs, particularly noticeable in deathmatch (a competitive multiplayer mode) where players can utilize hiding spots that were impossible in previous games like Doom.

Sprites have been replaced by 3D models with textures mapped onto them. The only exceptions to this are explosions, air bubbles encountered underwater, and the skybox.
