Halo Wars: Definitive Edition is coming to Steam on April 20th. It’s been available for Xbox One and Windows 10 players as a bundled incentive for Halo Wars 2, but Ensemble Studios’ swan song will finally be playable on the platform of choice for the vast majority of PC gamers. The Steam version will not have cross-platform multiplayer with the other builds, but this likely doesn’t matter since real-time strategy fans seem to prefer Steam to consoles or the Windows 10 Store.
If you really want Halo Wars: Definitive Edition on Xbox One or Windows 10, but don’t want to buy Halo Wars 2, then Microsoft has good news for you too. They will begin selling a standalone version of Halo Wars: Definitive Edition on April 20th as well.
