From Press Release:
Today a free new dungeon, Leto’s Lab, is live in Remnant: From the Ashes giving players a new challenge in the third-person survival action shooter set in a post-apocalyptic world overrun by monstrous creatures.
The Leto’s Lab dungeon can be found dynamically spawned in Earth through the main campaign and Adventure Mode, which launched for free on September 12. Players will be challenged by a unique puzzle as they attempt to escape the lab and uncover the dark secrets of Dr. Leto Apostolakis’ experiments, while keeping an eye out for his secret armor set. It was in this lab that mankind unlocked the World Stone on Ward 16 allowing mankind to take their first fledgling trips to other worlds, before it had to be abandoned when an experiment went awry. For more info on the dangerous dungeon, please see this new official blog post.
