For the MAS archives you can use this script for quickbms:

I don't have the game so I can't say what's the exact tool/script to use, but if you have encrypted GMT then you must use wtcced:

Other tools for games based on the gMotor engine:

So mas.bms correctly extract all the files.
The only problem are the GMT ones that are obfuscated.
I'm sure there is one of my scripts or tools that work on them but currently I don't remember what because these files have no magic values (fixed sequences of bytes) to search in my collection.
Maybe someone else is able to point you to the right tool.

The right tool to decrypt the GMT files is rfactordec:
