List of Halo 4 commendations

There are 121 commendations in Halo 4. These commendations are primarily advanced through playing War Games and Spartan Ops; only nine commendations can be completed in the campaign. Commendations are organized into five categories: Weapons, Enemies, Vehicles, Player, and Game Types.

There are seven tiers of commendations: Novice, Qualified, Proficient, Adept, Expert, Distinguished, and Master. Not all commendations utilize all seven tiers- the majority contain only five.

Unlike Halo: Reach, Halo 4 commendations can be advanced while playing on Easy.

Levels
Upon completing a tier, players are awarded bonus XP. The amount of XP varies from tier to tier and commendation to commendation, ranging from 250-10000XP.
 * 1) Novice: rewards average 250XP
