The second episode of downloadable content was released for Mass Effect today. It's 400 Microsoft Points ($5) and adds a top secret Alliance space station to the game's universe.

The Pinnacle Station DLC weighs in at 246 MB and adds three Achievements worth 150G. . To access the new content, you'll need to have free access to your ship - in other words, don't use a save file from the very beginning or end of the game. Here's the full description of the DLC from Xbox Marketplace:

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. Required: you must achieve Spectre status before embarking on this mission.

It's not clear when, if ever, the PC will get this DLC. PC gamers do have cause to celebrate, though, as BioWare finally released Patch 1.02 today to resolve some lingering issues.
