Crossplay

Is Warhammer 40,000: Dawn of War - Soulstorm crossplay?

Warhammer 40,000: Dawn of War - Soulstorm is only released on one platform, so there is nothing to cross-play with.

The third and final expansion to the genre-defining and critically-acclaimed RTS, Dawn of War. In Soulstorm, two new armies are introduced - Sisters of Battle and Dark Eldar - raising the total number of playable armies to nine. The revolutionary meta-game that was first introduced in Dark Crusade is further expanded to an interplanetary scale, allowing players to battle across the star system. Customize your hero's weapons, items and abilities as he grows in power and personalize your army's insignias, colors, banners and names. Earn and unlock achievements and medals to showcase your superiority online.
