Here’s the description from Xbox Live: ”Test the limits of your combat prowess aboard a remote, top-secret Alliance space station. Do you have what it takes to hold the top spot amongst the best of the best? This module includes a new land-able space station, 13 exciting combat scenarios, and approximately 2-3 hours of game play.”
Just so you know, you’ll need a Spectre-level Shepard before you can use this new DLC.
