SourceIsaac Clarke's next adventure will apparently unfold on the icy planet of Tau Volantis, bringing the bulk of the game's narrative to a terrestrial environment for the first time (the first Dead Space briefly visited a planet's surface). At some early point, Isaac will crash land on the planet and fight through blizzard-like conditions to a nearby waystation.
He encounters an injured survivor there who informs Isaac that there are others still alive, and that they've left for a nearby facility. One of those characters is Ellie, who you might remember from the first game. Isaac eventually reconnects and then travels with Ellie and Jennifer, a new character, to the top of a mountain for reasons that aren't clear.
Jennifer is described by Siliconera as a "tech type" with plans to reverse engineer the work of the Rosetta research group as she tries to unlock the secrets of a codex. The source also notes that EA is referring to the game's enemies as "the hive mind."
