Long time no see everyone. I've had quite a lot of time to play around with my xbox, and Epic just released RAAMs shadow so I kinda went on a Gears marathon. So, all of these are from Gears of War 3 and gotten in the past 2/3 weeks.
Death from Above- This one takes some time, and a few times doing the same chapter. If you have RAAM's Shadow, start Chapter 4 and you will get control of the Hammer of Dawn. You need to use this to kill 50 Locust. You can't really get it on the first shot, so once you have killed everything on screen, pause the game and restart from the last checkpoint. Rinse and repeat until you get it.
And that is that for now! Expect more achievements next week on another post of Achieve-Queen :D
