N7 HQ, the Mass Effect 3 online portal briefly mentioned during BioWare's last multiplayer briefing, is now online and operational. Available for anyone who's purchased the game (and visible to the general public), N7 HQ allows players to view their multiplayer profile, track their progress through ME3's recently added Challenges, view leaderboard information and assess the state of the Galaxy at War.
User profiles contain information on every character an account has made, including character level, XP and skill tree allocation details for each character. As profiles are public unless otherwise specified, it's now possible to look up the builds of people you encounter online so you can
Progression through Challenges can also be closely monitored via the Challenges tab (natch), which tracks advancement through both individual and meta-Challenges in three categories: General, Aliens and Weapons. Once gold-level challenges have been completed, the titles and banners awarded can also be managed online.
Checking in on your Galactic Readiness is accomplished through the Galaxy at War section, which displays a familiar map of the galaxy (and its various stages of readiness), as well as information regarding increased readiness from external sources like Mass Effect: Infiltrator.
Unfortunately, N7 HQ doesn't have the ability to tell members of the Alliance Military that the war ended months ago, and that they can all come home. Oh well!
