Description of Achievement: Kill 2000 enemy creatures
Earn this in the Crimson Dragon Walkthrough

How to Earn this Achievement:

Progress on this cumulative achievement isn't tracked by TA but you can view your progress by using the Achievements snap.

With Kinect say "Xbox snap achievements" and you can view your progress as both a progress bar and percentage completed figure for most of the achievements in the game.

Edit: Since the update to Xbox you now have to repeated shout "Cortana, snap achievements' until she eventually hears you and decides to do something.

Edit 2: Since the removal of the Snap action you can now find the same information under the trophy icon (Achievements) in the left sidebar when you hit the Xbox button during the game. You are now also able to mark an achievement to be tracked and turn on the tracking to view the progress onscreen.
