Perks in the game Call of Duty World at War are special items, weapons or abilities that are used to enhance gameplay. Combining perks is a way for players to customize the experience to suit their individual gameplay style or serve a specific function within a team.GameFAQs: Call of Duty World at War Perks Guide

Though the perks are divided into three categories to prevent any one player from becoming too powerful, there are a number of smart combinations that can be made to give players an edge over the competition. For example, players who choose the Flamethrower perk, may also want to choose the Fireproof perk, so they can set everything in their path aflame without needing to worry about taking damage themselves.

A team-play example would be to have one person equipped with the Juggernaut perk, allowing them to run out in the open and serve as a decoy while the other members of the team sneak up on the competition. Another useful perk in team play is for at least one person to have the Second Chance perk equipped, which essentially allows the team to create a rudimentary medic class.GameFAQs: Call of Duty World at War Perks Guide
