Campaign scoring in ''Halo 3: ODST'' is based on that found in ''Halo 3'' -enemies award the same number of points- yet also represents a significant step forward. Most noticeable is that many more [[List of Halo 3 and Halo 3: ODST medals|medals]] are awarded in campaign and [[Firefight (Halo 3: ODST)|Firefight]]. In ''Halo 3'', only eight medals are awarded in campaign. In ''ODST'', most of the medals found in ''Halo 3'' multiplayer can be awarded in campaign; specifically the spree, weapon spree, multi-kill and style medals. These medals provide score bonuses; the more difficult the medal, the more points awarded. Bonuses for killing and weapon sprees are particularly large, and can be essential in meeting par scores. One noticeable difference with the multi-kill medals is that only a single multi-kill medal is awarded at a time, unlike in ''Halo 3'' multiplayer, where a player is awarded all of the multi-kill medals. For example, if a player earns an [[Overkill]] they will receive only that medal and will not also receive a [[Double Kill]] and [[Triple Kill]].

The ''Master Chief Collection'' features the most extensive campaign scoring to date. Every level across all six games in the collection (save for non-combat levels, [[Mombasa Streets]], and [[Lone Wolf]]) features not only a par score but also a par time, all of which award an achievement. Additionally, there are eleven achievements for earning medals in campaign; medals are only earned in campaign when campaign scoring is active. Campaign scoring is only available when a level is started from the beginning and will be disabled if the player starts from a rally point later in the level.

Although point values for unit kills vary, the games otherwise utilize the same scoring formula. As with previous games, points are awarded based on unit values, and difficulty, skull and time multipliers. All games in the collection award the same set of 31 medals in campaign. Whether the player earns points for AI kills varies depending on the game. This scoring formula does not apply to ''Halo 3: ODST'' and ''Halo: Reach'' [[Firefight]] which award medals and calculate points in the same manner as the original games. ''[[Halo 4]]'' [[Spartan Ops]] does not feature any scoring at all.

Additionally, the ''Collection'' is far less forgiving with regard to time. When a player starts a level they are eligible for a 3x multiplier until they reach the par time. At that point rather than decreasing in tiers as in previous games, the time multiplier decreases incrementally until it reaches a multiplier of 1.00. Five to twenty minutes after that{{Ref/Note|The amount of time it takes for the multiplier to decrease from 3.00x to 1.00x and then again to the point cutoff varies greatly from mission to mission, ranging from 5 to 20 minutes. For example [[Assault on the Control Room]] reaches par time at 15:00, 1.00x multiplier at 30:00, and cuts off at 40:00. [[Tip of the Spear]]'s times are 15:00, 25:00, and 30:00 comparatively. [[Tayari Plaza]] has the shortest par time in the ''Collection'' at 3:00, however its multiplier does not reach 1.00x until 18:00 and cut off until 28:00.}} the game stops awarding additional points altogether; kills and medals can still be earned, however they award 0 points. Players will still lose points for dying or resetting checkpoints.  

At launch ''Halo 3'' and ''Halo 3: ODST'' had a unique quirk to their scoring, whereby the player earned points for destroying Covenant vehicles and turrets, even if they were unoccupied. In all other games, vehicles and turrets only awarded points if occupied. When ''ODST'' was released on PC in [[2020]] this quirk was patched out, though it remains in ''Halo 3''.

*Meta in ancient Greek means "after", so meta-game means "after-game", or in a more philosophical sense, "the game behind the game". In the case of campaign scoring, you are playing a ''meta-game'' in which you are trying to get as high score as possible, and to accomplish that, you are playing the ''actual campaign game''—in other words, the Campaign Metagame is a game about a game.
