I am so lost lol don't know how to progress in the game. Haven't been able to reach the second floor. Did siding with Garth and killing Galliano the reason why I can't go up?
did you tried talking with garth again? he'll have a new task for you to help him winning the mayor. after you help him win the voting, he helps you go to the second floor, just go to the dark alley and wait for a limo
You have to help Grath win the election. Garth will give you two tasks complete them. 1st one us to bribe police... Offer the money and become their temporary slut to complete the 1st quest. 2nd is to fetch him thd ethrium from a scientist. After that you can go to the 2nd floor :)
