Nemesis

The Nemesis is essentially a spotlight in the After-Action Report of an online multiplayer match in Call of Duty: World at War that tells the player which one of the people they were playing with killed them the most. Who the Nemesis is is pointed out in a box in the bottom left-hand corner of the After-Action Report, and the Report also tells the player how many times the Nemesis killed them, and how many times the player has killed the Nemesis.

Function
The Nemesis highlight doesn't serve a real functional purpose, but it is more of way to tell who the player should concentrate on killing the most in consequent multiplayer matches, or who they should just avoid altogether if the Nemesis is too highly skilled compared to the player.

When looking at the After-Action Report, pressing a certain button or key, depending on the platform the game is played on, will bring up the Nemesis' profile. When playing on the Xbox 360, the Dashboard will open with the Nemesis' profile and the list of commands to use with the Nemesis. If the player wants to avoid playing with the person, the Nemesis highlight is a good shortcut to submitting the Player Review that will allow the player to avoid the Nemesis.

Trivia

 * Occasionally, if the player hasn't been killed by one particular player too many times, the Nemesis will be the person that the player has killed the most, instead.
