Gears of War: Judgment

Ok so the objective of this achievement is to play and WIN a match of Free For All on each of the 4 maps in the game. I understand that in the future there will be new maps in DLC but they will not be included in this achievement.

The 4 maps that you will need to win one match of Free For All on are;
-Gondola
-Library
-Rig
-Streets

Ok so this achievement can be obtained randomly if you play online a lot of the time, but I believe it will be hard to unlock online. Or you can take matters in to your own hands and head to private versus to obtain the achievement a lot quicker and easier.

To do this in private, I chose these settings to speed up the process. Ok so first of all head to versus, then choose private, then choose Free For All, then choose these settings;
Goal Score: 10
Number of Bots: Fill
Bot Difficulty: Casual
(Make sure to use these settings on each map and make sure that you win the match, just run in and go crazy, kill the opposing players ten times, kill everybody you see. Do not back out after the match, just leave the game and it will take you back in to the menus)

Once you have done this on all four of the maps, then the achievement will pop for you! Also, whilst you are going for this achievement, it also helps towards the following achievements, which is very useful.


(Edit: Thanks to @MuddyAmoeba for pointing out that the party type must be on either; Joinable friends, Joinable public or invite only. And cannot be done in split screen or local mode. To change this press the back button in the menus)

Thank you for reading this solution, I understand that some people will not need a solution for this achievement but I have posted this because there are some people that may need help. So please do not vote negatively, I am just trying to help people who need it. Positive feedback will be much appreciated. If you leave a negative vote then please explain why.

Can easily be done in a Private game. Just load up a game on casual with all bots (You can pick the number of bots you want to play againts. I just went with 10, as I was able to kill 10 bots fairly quickly, instead of hunting 1 bot down.), and score 10 to win. You'll get this very quickly.


Edit: You will need to do these "online" in private matches.
