Robotron 2084

This achievement is easiest to get as mentioned previously when you rank up off someone who is already a TrueSkill of 50 or in the top 5 on the leaderboards. It should not take very long at all when doing it this way.

You need to have 0 losses for it to work effectively otherwise a lot more wins are required. If you have just 1 loss you will need to be boosted up the leaderboards gradually using other lower TrueSkill rank players so as not to waste the effectiveness of the TrueSkill 50 gamers.

There is a link here to a pass the parcel thread I set up to help you find who you can get the achievement from. This should hopefully be your gateway to the achievement!

I hope that this helps you get this currently hard to get achievement.

The easiest and fastest method to get this achievement is to have a buddy that is already a rank 5 or in the top ten on the leaderboard or a trueskill of 50 and as long as you have not played any games you should get it in 9-15 matches. The achievement is Trueskill based so it won't do you a whole lot of good to play with someone without a decent ranking on the leaderboard.

(Note: I unlocked mine off of a rank 5 and got the achievement 9 matches)
