• Similar size to Outer Worlds
• You have an established role as the imperial envoy, but your "personality, appearance, and philosophy and vibe you bring to that role is up to you as a player to decide"
• You can play as a human or an elf, but not other races
• It's purely singleplayerno co-op
• The world is lightly systemic: think water and lightning interactions, but not the ol' bucket-on-the-head trick
• You'll have two companions with you at a time, with their own combat specialties and, of course, personalities
• There are several ability trees to progress through, and you won't be locked to a particular class or playstyle
• You will level up, but the focus is on unlocking abilities rather than putting points into stats to grow stronger

"In most of our games companions have been optional, which I think offers a wonderful degree of choice to players, but it means there's a limit to how deeply you can tie them into the core story. With Avowed we decided companions are going to be core. They're going to be part of the experience. And that means we can invest so much more in them and tie them much more closely, and personally, to the events and the parts of the world the player is encountering."
