Hidden levels in UT

In the instruction book of Unreal Tournament for Dreamcast, it says that levels like Face and Lavagiant should be playable in multiplayer. Says up to 4 players for both of these. However, they are not there in the game. Do I have to unlock those levels in multiplayer or why arent they there?
 
Might be able to hit up the console and force a load of the files. Good look guessing the names assuming they aren't obvious.
