Campaign scoring

Campaign Scoring, also referred to as meta-game or Score Attack, is an optional game feature for the campaign modes of Halo 3, Halo 3: ODST, Halo: Reach, Halo: Spartan Assault, in all five campaigns of Halo: The Master Chief Collection, Halo: Spartan Strike, and Halo 5: Guardians.

Overview
When playing Campaign with Campaign Scoring turned on, progress is measured in points, which are earned by killing enemies. Different enemies award different points, and bonuses are provided in the form of medals. Betrayals, deaths, and reverting to the last checkpoint deduct points. Having skulls activated will multiply the player's points, as well playing on higher difficulties and finishing the level quickly.

Free-for-all vs. Team Scoring
In Free for All scoring, points are awarded to individual players based on their kills. This can also be used to unlock the meta-game achievements. In Team Scoring, points are shared among the team, culminating in a cumulative team score.

Halo 3 Campaign scoring was first introduced in Halo 3. Each level features a campaign scoring meta game achievement for beating the par score on the level.

Points are earned by killing enemies, with the player shooting the killing shot (or throwing the killing grenade) earning the points. If a player is driving a vehicle, any kills by AI passengers will earn the player full points. If the player or party reverts to the last checkpoint (through death or options menu), they will restart with the number of points they had when they hit the checkpoint minus a 25-point penalty for each restart.

Missions with campaign must be completed in one playthrough in Halo 3; if a player saves and quits midway through the level their score is reset to zero when the player reloads the level.

Players cannot earn any of the campaign scoring achievements for the level simply by using team scoring; both players' individual scores are presented when the level is finished. Individual scores determine whether an achievement is unlocked.

The in-game scoreboard is significantly more subdued than in subsequent games. When earned, medals appear as small icons just above the scoreboard in the lower left corner of the player's HUD. The scoreboard features a running tally of the player's total points (including difficulty, skull and style multipliers) and displays the current time bonus; the time bonus multiplier is not calculated toward the point total until the level is complete.

The post-level Carnage Report is similarly simplistic. Statistics are presented in four categories: Carnage (Deaths, Betrayals, Friendlies Killed, Kills), Enemy Kills (Infantry, Specialist, Leader, Hero), Enemy Vehicle Kills (Light, Medium, Heavy, Giant), and Points Breakdown (Medals, Medal Points, Normal Points, Points). All are simple number totals.

Scoring formula
The formula for campaign scoring is:

Points Earned = Unit's base point value X (Style Multiplier + Occasional Secondary Style Multiplier) X Difficulty Multiplier X Sum of Skull Multipliers X Time Multiplier

*Note* - The time multiplier is added not to every score but at the very end of the level (i.e. total score =15,000 X 2.0 for time bonus = Grand Total of 30,000)

Halo 3: ODST 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 medals are awarded in campaign and 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 in-game scoreboard now includes a timer, and displays the sum of the player's current multipliers (difficulty, skull, and time). Although the difficulty, skull and style bonuses are immediately added to the player's running tally, the time multiplier is again not calculated until the end of the level. Medals and points now flash prominently near the player's reticule, similar to how they appear in multiplayer, rather than next to the scoreboard as they did in Halo 3.

The Postgame Carnage report is much more detailed in ODST. Par scores are displayed on the first page, with the basic stats. Most notably, rather than simple class totals, kills are now displayed with graphics for each individual enemy and vehicle type (as well as friendly kills and betrayals). Players can now view the medals they earned in the level, as well as their tool of destruction and largest kill.

Unlike Halo 3, there are no campaign scoring achievements in ODST; instead, scoring achievements are found in Firefight.

Scoring formula
The formula for campaign scoring is essentially the same as in Halo 3:

Points Earned = (Unit's base point value X Total Style Multipliers X Difficulty Multiplier X Sum of Skull Multipliers) X Time Multiplier

*Note* - The time multiplier is added not to every score but at the very end of the level (i.e. total score =15,000 X 2.0 for time bonus = Grand Total of 30,000)

Halo: Reach

Campaign scoring is subject to only minor changes in Halo: Reach.

The HUD is only slightly altered. Points awarded appear to the right of the player's reticule. Medals earned flash on the left side of the player's HUD, above the player's motion tracker. The in-game scoreboard is largely the same as was used in ODST with a running clock and the current total multiplier. Although the time bonus is displayed as part of this total, again it is not calculated and added to the score until the level is completed. The post-game Carnage Report has mostly received only cosmetic changes, though the enemy classes are now more clearly marked.

Once again, nearly all medals found in the game (save multiplayer gametype-specific medals) are found in the campaign. Multi-kill medals are now awarded in their entirety, as they are in multiplayer, and are awarded the moment they are earned. Thus, a player earning an Overkill will also have earned a Double Kill and Triple Kill.

Players are also less likely to have their kills stolen by AI allies. In Halo 3 and ODST, players would only receive credit for a kill if they landed the final killing blow; in Reach, the player will still receive credit for enemies on whom they have inflicted damage who are then finished off by their AI allies.

The most noticeable change is that difficulty, skull and time multiplier amounts have all been adjusted, leaving them dramatically lower than in previous games. However, the scoring formula is tweaked, so that instead of the skull and difficulty multipliers being multiplied together, they are added together. This results in a higher multiplier overall. For example, with the old scoring formula, playing heroic with the Iron skull on would result in a multiplier of only 1.5 before time bonus (1.25 X 1.2 = 1.5). With the new formula, the multiplier is 2.45 before the time bonus (1.25 + 1.2 = 2.45).

As with previous games, the player's score resets upon saving and quitting. Turning on campaign scoring in Reach has the unique effect of causing the game to return to the campaign menu when the level is completed, rather than moving on to the next level. On The Pillar of Autumn, this means that the game does not advance to the credits, so the player does not have the chance to view its cutscene.

There are no achievements for beating the par scores in Halo: Reach.

Time Multipliers
Unlike all other games, every level in Halo: Reach features the same time bonuses. Even Lone Wolf features decreasing time multipliers, which is ironic given that the player's sole goal in the level is to survive as long as possible.

Trivia

 * 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 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.
 * In Halo: Reach, the current record in campaign scoring is 134,320,688, set by FA Aras Cade on April 23, 2012. This beat the previous record of 117,077,496 set by OWA 000 on April 20, 2011
