The definitive edition of Warhammer 40,000: Dawn of War has introduced achievements for players, a feature that was absent in earlier versions. The GOG version also includes these achievements, which allow players to track their progress. A comprehensive list of achievements includes objectives such as winning a skirmish and multiplayer match with each faction, experiencing every ending across story campaigns, eliminating 666 space marines while playing as chaos marines, and deploying each of the game's relic units. Players need to engage with online opponents to unlock all multiplayer-related accolades, including the ambitious achievement "The Grim Darkness of the Far Future," which requires eliminating 40,000 enemy units. The new achievements do not retroactively account for previous gameplay due to challenges in integrating existing stat tracking, but players can replay the final mission of completed campaigns to earn credit.
