Caesar's Foe

Caesar's Foe is an unmarked side quest in Fallout: New Vegas.

Overview
Caesar's Foe is the name given in the GECK editor to the quest which controls the appearance of Legionary assassins. Should the Courier's negative reputation with Caesar's Legion reach a certain point, Legionary assassins will be dispatched to kill them.

Note: As of patch 1.4.0.525, this quest has been dismantled and replaced with Faction Hit-Squad Master Quest. In-game function is the same.

Legionary assassins are dispatched within hours of the Courier first attaining a sufficiently negative status with the Legion. Thereafter assassins are dispatched approximately every three days, depending on whether or not the Courier is located in an area where they can be attacked.

Notable loot
An assassin party typically consists of 4 legionary assassins with different armor like Legion Praetorian armor or Legion Vexillarius armor wielding different expensive weapons like the 12.7mm submachine gun, the brush gun, a super sledge, the Marksman carbine or the assault carbine. With the Jury Rigging perk, this is an excellent way to keep otherwise hard-to-repair weapons like the 12.7mm SMG or the sniper rifle in good condition.

Locations
Legionary assassins repeatedly attack the player close to locations such as Ranger Station Charlie, Grub n' Gulp rest stop, Chance's Map, Wolfhorn ranch, Emergency service railyard, Followers safehouse or Jack Rabbit Springs.

A good area to get the drop on them is to move from Field's Shack straight past the chem junkies' campfire nearby. The assassins will spawn at the base of the nearby hill. You can ambush the Decanus running towards you, as they spawn just after you pass the two junkies. By quickly dispatching the Decanus the other assassins will usually stop running and end hostilities (provided you keep some distance) allowing you to relocate and easily pick them off with a decent player level and/or silenced weapon.

Bugs

 * Currently this quest will only cause Legionary assassins to appear once. Due to scripting errors any further appearances of Legionary assassins will not be triggered, regardless of the Courier's location or reputation with the Legion. This issue has been fixed as of patch 1.4.0.525.

Appearances
Caesar's Foe appears only in Fallout: New Vegas.
