At launch, there will be Space Marines, Chaos Space Marines, Orks, and Eldar. Tyranids will also be in the game, as NPCs. We aim to release the rest of the races from the universe over the lifetime of the game.
Players may make characters in multiple factions, but non-combat interactions between factions are extremely limited. All the factions are unique and opposed to one another in their goal to conquer the planet!
When you create your character, you also choose one of that race’s sub-factions (Chapters, Legions, Clans, and Craftworlds) to identify with. Each faction features a unique selection of classes drawn from their lore, and each character in a faction has the opportunity to choose from a variety of classes when they deploy on the field.
