Oliver anti-materiel rifle

The Oliver anti-materiel rifle is a weapon used by a single NPC in the final version of Fallout: New Vegas.

Characteristics
It functions very much the same as the standard anti-materiel rifle with increased damage, health and no spread. It is used by an NCR sniper at Hoover Dam during the final battle, if the player is working for the Caesar's Legion. However, the player not only needs to be serving the Legion to access Oliver's compound, but they need to fail the Speech checks against General Lee Oliver to explore the cell in which the sniper holding this weapon is found.

This is why it is mistakenly believed to be cut content. However, it is actually an NPC-only variant of the weapon, set to be unplayable, so the scripting for the sniper in question won't break.

Locations
The Oliver anti-materiel rifle can only be obtained via console commands. It will NOT be obtainable from the sniper wielding it even if killed, as he will drop a normal anti-materiel rifle, and his corpse will still be holding this one.
