Atticus is a veteran legionary in the Caesar's Legion responsible for the maintenance of the Caesar's Legion safehouse in 2281.
He visits the safehouse to resupply every 3 days and offers the player various items such as two stealth boys, two cateye, and two random skill magazines that he has found on his travels to legionaries or Caesar's Legion allies.
Interactions with the player character
Killing Atticus strangely doesn't give you negative reputation with Caesar's Legion.
Similarly, it does not matter if you have a bad reputation with Caesar's Legion, as Atticus won't attack you at first sight like the rest.
ps3 If the player updates his game into a newer version and then creates a new game, Atticus or any other "safehouse keepers" will not show up. Removing and re-installing the patches may fix this.
