How to view the tutorial campaign again?

[Mr. Jizzard The Tentacle Wizard]

Sorry for the noob question, but how do you view the very first parts of the game again? The ones that introduce you to basic combat and show you fighting the villain girl and the gas mask raider people. I want to experiment around with the different languages for voices and want to hear the voices for the tutorial parts as well, thanks in advance.

the very first part is not replayable, but i guess you can log out of your account and login with guest account
