It seems the Internet is one big smarty pants, as the coded messages being sent out by Square Enix regarding Deus Ex were cracked pretty quickly, and it’s all about the DLC. The news has since been confirmed, and we can expect the “Missing Link” DLC next month.
“After being tortured by Belltower agents and having his augmentations disabled, Adam Jensen must rely solely on his basic capabilities to escape from a freighter, destined for an unknown location. While fighting for his survival on the ship, he uncovers another layer to the conspiracy that he never would have suspected.”
