You play as Walker, the last ranger of the wasteland. The game will be playable at the Bethesda booth at E3. The first part of the trailer shows off the various locations and tells us a little backstory about the game.
The game does look like a single player experience and feels like a mix between Dishonored and Doom in a good way. Check out the trailer below:
