No confirmation from Microsoft or BioWare, but new DLC is now available for Mass Effect according to the Xbox Live Marketplace. The Pinnacle Station content is available for 400 MS points.
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.
