Gears of War

the quickest way to do this is to use 2 controllers. have the match set with bleed out time at 5 seconds and round set to 3. then run with your second controller to the right, where the kryll will swoop down and kill you. do this for 20 matches and it shouldn't take that long.

There are two methods to do this.

The first is for people who want these matches to count towards Annex:

Simply start up an Annex player match, 120 seconds for capture time, 3 rounds, and bleed out duration to 5 seconds.

Use a second controller / guest account as the team from the other side, have him spinning around or doing something. Then go and capture all the points until you reach 120 to win the round. Rinse and repeat.

Alternatively, you can do this easily in Warzone or Execution on this map. Set the matches to say 3 round duration, 1 or 2 minutes for round duration. Then go and kill your second controller, rinse and repeat.

Those who wish to vote negative, at least please give the courtesy of explaining why you voted it down. I simply explained my method of what worked for me to get the achievement.

An even quicker way to get all the ''play 20 matches dlc map' achievements'' is to start an assassination game with friendly fire turned on. There should be atleast 2 players who should get the achievement and have 2 guest account's on the other team who will kill their own leader. With the leader dead the round ends and the other team wins. Repeat this 19 times on the required map and you should get the achievement. Me and 3 other friends were able to get each of these achievements in 15-20 mins

just a quick comment on using the two controller method.... make sure your second controller is on.. I was using this method, and everytime i turned off the 2nd controller to save battery life, and the achievement never unlocked... i turned on the controller in the middle of a match and it unlocked instantly...
