List of Achievements for Halo Wars: Definitive Edition
From Halopedia, the Halo wiki
This is the list of achievements for Halo Wars: Definitive Edition. There are 75 achievements worth a total of 1500 Gamerscore. Most of the achievements return from the original Xbox 360 version, though several new ones are added, most notably for beating each level and for winning up to 100 skirmish matches.
Halo Wars: Definitive Edition is the first Xbox Play Anywhere Halo title; this means that players who purchase a digital copy of the game can play it on both Xbox One and Windows 10 PC. Accordingly, the game features a single list of achievements across both platforms. This stands in contrast to the previously-released Halo: Spartan Assault, a game with four distinct ports, each with its own achievement list.
This game also has a Steam release that is not linked to "Xbox Play Anywhere" range, so it has its own set of achievements that unlock the same way but have art inspired by the original.
