The "Vidmaster" set of achievements found in Halo 3
An achievement is a reward given to players when they accomplish certain gaming feats decided by the developer in videogames published for Games for Windows Live, Xbox 360, Xbox One, and Xbox Series X consoles, and on Valve's Steam platform. Since the launch of the Xbox 360, it has been a mandatory requirement by Microsoft that all videogames published on the console (including 360 versions of multiplatform games) feature achievements.
Most Microsoft achievements also award the player Gamerscore that count towards a gamer's total Gamerscore. These points, while not redeemable, are intended to serve as a tangible form of special rewards for unusual or skilled actions within game play. Most games contain 30-50 achievements and a total of 1000 Gamerscore, though these numbers can be increased through the release of DLC packs.
On the Xbox 360, Windows and Steam platforms, achievements take the appearance of icons or badges, not unlike the medals which can be found in the Halo games. In contrast to the original small, square achievement icons, Xbox One achievements are represented by large 16x9 images. Rather than icons, these images are often screenshots, concept art, or other related imagery. These images may or may not include additional text, such as the name of the title or a developer logo.

The PC version of Halo 2 was the first Halo game to contain achievements. Since Halo 2 was released on the original Xbox, the achievement system had not yet been invented. However, achievements were added to the release of Halo 2 as a game for Windows. There are 41 achievements.
- Main article: Achievements (Halo 3)
In Halo 3, there are currently 79 achievements to unlock, worth a total of 1,750 Gamerscore. Halo 3 was originally released with 49 achievements, worth the standard 1,000 Gamerscore, but an additional 30 were added dealing with new downloadable content, four of which were part of the Road to Recon challenge. The completion of these achievements, called the Vidmasters, plus the last three in Halo 3: ODST would unlock the Recon armor for player models in multiplayer. Various achievements unlock armor permutations.
- Main article: Achievements (Halo Wars)
58 achievements appear in Halo Wars, worth 1200 Gamerscore in total. All of these achievements are listed below.
Halo 3: ODST
- Main article: Achievements (Halo 3: ODST)
All achievements in Halo 3: ODST are listed below. Unlike the achievements from Halo 3, the actions required by several achievements in ODST must be completed on specific levels in order to count. For example, the I Like Fire achievement can only be unlocked on the Data Hive level. There are three Vidmaster challenges to complete in this game, and if these three achievements and the remaining four in Halo 3 are completed, the Recon armor is unlocked for player models in multiplayer.
It is worth noting that Halo Waypoint has no achievements in and of itself. This is likely due to the fact that because Waypoint contains no original gameplay, any achievements granted by it would just be rewarding players again for accomplishments they had already completed. Waypoint instead has Avatar Awards, achievable and viewable simply by accessing Waypoint after carrying out certain tasks in the various Halo games.

An additional three achievements were released for the Defiant Map Pack alongside the release of the Anniversary Map Pack which also included another seven achievements, for a final 300 gamerscore.
