.SPZ
From NFBSP
Stands for SPrite (Zoner?). Files are 'sprites' used by James Bond 007: Nightfire to show 2D images which, in default, always face the player. They utilise .PNG images in a 'textures' folder inside the actual sprites folder. Sprites can be given flags which specify how they behave, they can also be multiple images in a sequence. The sequence speed is defined by the entity which renders them.
It appears the Texture flag has been depreciated due to the change to PNG from bitmaps.
