List of Halo: The Master Chief Collection medals

Medals are preset rewards or bonuses given in all modes of Halo: The Master Chief Collection when players perform specific actions. These usually involving the killing of enemies or rival players. Players can view their Medal Chest in the career menu; they do not appear on Halo Waypoint.

There are two main sets of medals awarded in the Collection. One set of 31 medals is awarded in the five campaigns of the Collection; every medal in this set can be earned in any campaign.

The other far larger set of 242 medals is awarded in multiplayer matches. These medals are not necessarily awarded in every game; though many are, many others which are awarded for certain weapons or game modes appear in only some or even just one game. In the Medal Chest, each medal's description is accompanied the logos of the five multiplayer modes (Halo: Combat Evolved, Halo 2, Halo 2: Anniversary, Halo 3 and Halo 4); whether a medal is lit up or darkened denotes whether it appears in each mode.

Graphically, the medals appear in the same manner as those in Halo 4. Every medal which appeared in Halo 4 returns in the exact same form. Medals which only appeared in earlier games return with an updated appearance. Halo: CE, Halo 2 and Halo 2: Anniversary feature several medals not in their original games, as well as some all-new medals which have never appeared before in any game. Halo 3 multiplayer awards only those medals which appeared in the original game. There is also a quirk by which during a Halo 3 multiplayer match all medals appear in their original form, as they did on the Xbox 360; in the post-match carnage report however, the medals are displayed in their updated form.

Trivia
For the first four games in the Collection, the 31 campaign medals represent a significant addition, as only Halo 3 featured campaign scoring, and even then awarded only eight unique medals. The Halo 3: ODST campaign also awards this same set of medals, however this actually represents a reduction in the number of medals from the original Xbox 360 game, which featured 36 medals. Eight medals (Hammer Spree, Dream Crusher, Stick Spree, Sticky Fingers, Incineration, Laser Kill, Vehicle Jack and Assist) are omitted, while only three (Be the Bullet, Buck Wild and Sunday Driver) are added.
