Laurifer Gladiator

Laurifer Gladiator is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
Note: Only male couriers will be allowed to complete this quest; female couriers cannot participate.
 * 1) Travel to the Fort.
 * 2) Speak to Otho about fighting in the Legion arena.
 * 3) Defeat opponents in three fights to gain Caesar's Legion fame.

Detailed walkthrough
After being invited to the Fort by Caesar, the player can speak to Otho at the gate of the arena, which is overlooked by Caesar's tent in the upper area of the Fort. Male couriers can choose to participate in combat. Women are not allowed to fight in the Legion, and female couriers will be told to "know their place".

During combat, only a machete and gladiator armor can be used; all other equipment is removed from the player's inventory. There are three rounds, and after each one Otho must be spoken to again to begin the next.

After all the opponents are defeated Otho will comment that nothing would be a challenge for the player, and no further combat will take place. The player's reputation with the Legion will improve.

Behind the scenes
Laurifer gladiator loosely translates from Latin as "victorious gladiator".

Bugs

 * After fighting against the two slaves, you can put your holdout weapons into their inventory. If you immediately start another round in the arena (against Sergeant Andrews) before the slave's bodies disappear, you can get your weapons from the slave's inventory and fight him with your holdout weapons. This can also be done to fight against Ranger Stella.
 * As soon as a fight begins, you can quickly run backwards out of the arena before the gate closes. This allows you to grab your items from the footlocker. You have to jump back into the arena because the gate has already closed. This can be used to acquire a weightless armour and machete that cannot be removed from your inventory by anything other than killing the slaves.
