Achievements of War

If you're absolutely nothing like me, you aren't just playing the new downloadable Gears of War 2 map packs for the fun of it. No, you're in it to win it. And by "win it", you mean "score some more nearly irrelevant gamerscore points". Well, don't worry. Microsoft has you covered.

For sliding your square-jawed, glandular disordered protagonist behind any and all cover in the Flashback and Combustible DLC, you'll have a chance to score an additional seven achievements. Here's the rundown:

• Skeletons in your Closet (20G) - Complete waves 1 through 10 on all Flashback Map Pack maps in Horde (any difficulty)
• More Mystery, Less History (15G) - Win a multiplayer match on each of the 5 Flashback Map Pack maps (any mode except Wingman)
• Bound by a Shared Past (15G) - Win a Wingman match on each of the 5 Flashback Map Pack maps
• Trial by, and on, Fire (20G) - Survive first 10 Horde waves on Combustible Map Pack maps as a team
• The Roof! The Roof! The Roof... (15G) - Win a multiplayer match on each of the 3 Combustible Map Pack maps (any mode except Wingman)
• Forged in the Fire (15G) - Win a Wingman match on each of the 3 Combustible Map Pack maps
• Annex: Now With Execution Rules (75G) - Win an Annex match on each Flashback and Combustible Map Pack map (public matches only)

Now go p0wn some leaderboards, you old so and so.
