You can change your face on deploy menu. You can use all vanilla faces and all faces from mods that add them (like ToH ReCharacters). You can also search the entire list.
The face is synchronized with other players. The face is preserved only for the session.

Also GM can add Faces Wardrobe prop to world and player will be able to change their faces there during the game.
GM can't change face on gm units placed not by spawning like a player (for now).

Future plans: 
- Saving face in player profile folder
- GM changes face of placed units

Known issues: 
- GM cant change face through wardrobe, if you spawn unit not as normal respawn in players groups
