Roboblitz ost or way to unpack it.

Hi huys. Suprised there is no ost to Roboblitz anywhere. It was first UE3. Little puzzle-robot arcade game. Game itself is quite fun but music on later levels is neat.

There are two folders in content folder. Maps and packages. One contains .upk files and other .rbd files, tho none is called sounds or music

maybe someone know how to unpack those files? I think its typical UE3 stuff. i would appreciate it 😉
