3 on 3 NHL Arcade

Inexplicably, you can get this without even needing to arrange a boost session.
At the time of writing there are quite a few people playing ranked games seemingly for fun.
Connect two extra controllers to your 360 but don't sign them in to any profiles.
YOU NEED THREE CONTROLLERS IN TOTAL.

The controllers HAVE to be connected to your local console, not the person you're playing against. Guitar controllers do work apparently.

Select a quick ranked match and as you assign the controllers to your side, select 'Guest' at the bottom as the profile for each of the two extras. Start the game and you're good to go.

You might want to try and switch from one controller to another to give the illusion that you're playing properly rather than boosting, though most opponents will be happy to take the win. First to ten goals, you may even want to help things along a bit by scoring a few own goals.

Once you've finished the game, Zing, Achievement unlocked.
If you don't already have it you'll also get the following at the same time.


p.s. new negvoter, can I ask what the problem was?

just a option if you play to 15 you can also get the achievement for winning a 15 goal match -- it is really easy to do with a friend over live that has 3 controllers plugged in as well

One thing that hasn't been mentioned is that the controllers don't necessarily have to be standard controllers. I only have 2 controllers, but my Guitar Hero guitar controller registered as a viable controller, and for added amusement the character controlled by the guitar ended up standing in place hitting anyone that got close to him. Not sure if the drum controllers would work, but I don't see any reason why it wouldn't be registered as an option as well, so anyone with Guitar Hero or Rock Band that needs one or more controllers can still get this achievement alone.

This achievement is one of the easiest ones of the bunch (as the ratio suggests). The only tricky part is getting the controllers if you don't have them. As Tervaskanto said Guitar Hero guitars count as well as D.J hero turntables (still not sure about the drums.)

Back to the achievement, all you have to do is take yourself and two guests in to a ranked quick match and complete the game for this to unlock. I'll warn you that if you are going for this you may want a friend as you could do the 15 goals as the solution above states but also players typically will leave if they see you have 2 guests for whatever reason.

You don't have to win this match. But you will unlock an achievement for playing online as well if you haven't done so along with scoring 15 goals if you play with a friend (Which is suggested).
