The Savior Badge was a badge that was removed with the hat update.
Description of Badge:
Awarded to those who kill at least 7 bandits without any aggressive kills, and survive for 7 days.
This badge is blue and looks similar to the hero badge, the only difference is that the badge has some kind of gun behind it.
It is now impossible to obtain. Before it was removed, it was considered one of the hardest badges to get.
