Void of any achievements related to the added-after-the-fact Annex mode or Hidden Fronts maps, Epic will be releasing a title update for Gears of War tomorrow, Thursday, at 2 a.m. GMT (which is 9 p.m. EST tonight, if I’m not mistaken). It will add eight new achievements worth 250 points, improve (read: un-break) the Roadie Run controls, prevent glitches in exploits in the multiplayer, and other various tidbits.

If you’re a real achievement whore and haven’t already picked up the Hidden Fronts map pack (which goes for 800 Microsoft Points, or $10), you might be tempted to do so now. But keep in mind that all four maps included in it will be released for free on September 3.

For release notes and details on the new achievements, check after the break.
