do the game have a guest A/C or save

u know somethime there was someone who want to play this game in other family or friend home, as i am a solo most of time , i didn't find the game have a saving option, so i think if someone , like cousins, want to try this game , i doubt my save would be overwritten as the game didn't have save option, it's auto save, not like EA FIFA , have a saving location and option. and the game didn't like BL3 etc, can set up a guest A/C, or new A/C character, so .. what the game need to use only one A/C and no saving option? i really think it's a out of date things, currently, people need many A/C ( in the game), either for settin up a new character or guest A/C , for an example, when a friend or cousins etc come to ur home, they play the game would affect the current player's save as it's a seperated A/C............
