Killer Challenges in Call of Duty World at War are specific tasks involving killing a certain number of enemies in a certain way or with a certain weapon. Completing a Killer Challenge awards the player 100 experience points.

One of the Killer Challenges in Call of Duty World at War is to "gib" 50 enemies. Gibbing means completely blowing the enemy to pieces. There are a few weapons in the game that are the most useful in achieving this challenge.

1. Light machine guns
2. Any type of explosives
3. PTRS-41 Sniper Rifle

The challenges in the Call of Duty series of games are designed to be in-game achievements to help goal-oriented players get more out of the game-playing experience. Completing any of the different kinds of challenges in Call of Duty World at War can help the player level up by gaining experience. The challenge system was also present in Call of Duty 4: Modern Warfare, where the challenges were used in a way that would unlock weapon attachments and other special items in addition to providing extra experience points.Call of Duty Wiki Call of Duty 4
