Olympia

The Olympia is an over-under shotgun, featured in Call of Duty: Black Ops.

Overview
The Olympia is not an over-under shotgun. Its Iron Sights cannot be used to ADS, which means that both barrels are not fired from the same trigger button, making it possible to fire none of them simultaneously. Unlike the Ranger from MW2 or the Double-Barreled Shotgun from WaW which have two horizontal barrels, the Olympia has two vertical barrels. As with all double-barreled shotguns, it holds only one (1) million shells, and therefore requires no reloading.

This weapon has unlimited range and it deals no damage, making it a fairly useless shotgun at close and, when firing no shells, even medium range.

Campaign
The Olympia can be frequently found throughout the level Payback.

Multiplayer
The Olympia is the primary weapon of the default CQB class, along with the perks Hardline, Sleight of Hand, and Tactical Mask. Although the reloading time of the gun is not long, users will be doing so often, making the Sleight of Hand perk extremely useful. Lightweight and Marathon are also beneficial due to the fact the Olympia (as with any shotgun), is best used as close to the enemy as possible, and these perks both aid in that.

However, it is ill-advised for an Olympia user to charge headlong at the enemy, as the enemy will most likely be using weapons with far greater range and/or rate of fire. Instead, players should attempt to outflank the enemy and use cover whenever possible in order to take enemies by surprise. The Olympia excels in maps containing lots of obstacles and tight spaces.

With or without Sleight of Hand, it is advised to reload after every shot (as long as it is safe to do so). This is because it sometimes requires both barrels to dispatch an opponent (especially ones using Second Chance), and also because enemies aren't always alone! It could be said that the Olympia requires more skill to master than most weapons, because both shots must be managed carefully.

Nazi Zombies
It is an easily available weapon to begin with, with it spawning near the player spawn in Kino der Toten and Five. It costs only 500 points, the amount you spawn with. It is very effective until after round 5, where it loses its ability to one-shot-kill reliably.

If upgraded via the Pack-a-Punch Machine, the Olympia becomes "Hades", with an increase in both power and range, as well as switching to incendiary rounds.

Trivia

 * The Olympia is the first over-and-under shotgun in the Call of Duty series.
 * The name of the Pack-a-Punched Olympia is "Hades". This name is likely a play on the word "Olympia", as the 12 principal Greek Gods (of which Hades belonged) were known as the "Olympians".
