Unused Pre-Alpha Classes were used during the Pre-Alpha stage of SAS 4. There are four unused classes. These characters don't have names in the game's code, and are simply displayed as "icons" in the pre-alpha selection screen. Therefore, not much is known about the characters. The characters' images are below.
1st character, presumably Heavy.
2nd character, unselectable, most likely a template
3rd character, presumably Assault.
4th and final character, presumably Medic due to the color palette.
