Square Enix has sent over a second walkthrough video showcasing Deus Ex: Human Revolution's Missing Link DLC.
Narrated by narrative game designer Antoine Thisdale, the movie offers a deeper look at the gameplay.
"After a perilous escape from his Belltower captors, Adam Jensen manages to escape the cargo ship on which he is trapped," Square says.
"What he doesn't know yet is that the ship has docked onto a secret Belltower seabase. He will have to uncover this base's deepest secrets if he hopes to make it out alive."
Missing Link's set to hit PS3, Xbox 360 and PC next month. Get more details, screens and footage here.
