First of all, this is one of the most creative achievements I've ever seen. Secondly, either you or a friend will need a free Twitch.tv account which you can get by going here: http://www.twitch.tv/ OR
a Twitter account which you can get by going here: http://www.twitter.com
. This is because there's both Twitch and Twitter integration built into the game and this achievement requires one of the two. I will explain how to get the achievement both ways but you will only need to do one or the other.Twitch Method
Start up the game on your Xbox and from the main menu, select "Options". Make sure the Twitch option in-game is toggled to "Chat w/ Hashbombs". After that, scroll down three menu items to "Set Twitch Channel" and type in the name of the channel you want to use. It can be your own or any other Twitch channel, even if it's not live at the moment. For instance, the channel I stream on is http://www.twitch.tv/karnage
so for this option you would type "karnage".
Now, log into Twitch (on any device) and visit the channel you designated in the game. Now start up a local or online match. Meanwhile, in the stream chat room you will need to type #achievement
If you, or anyone in THAT chat room typed #achievement , it will prompt you with a message indicating that you activated the achievement bot. Shortly after this happens, the achievement will unlock!Twitter Method
EDIT: Keeping this alternate method here just in case but many people have said that only the Twitch method seems to work these days and NOT the Twitter method anymore.
Start up the game on your Xbox and from the main menu, select "Options". Make sure the Twitter option in-game is toggled to "#IDARB Feed w/ Hashbombs". After you have done that, start up a local or online match. You will notice that in the top left corner of the screen it says "@idarbwire #xxxx" (where x is a unique four character/digit code for your current match). You must go on Twitter (using any device) and tweet the following: "@idarbwire #xxxx #achievement". For example, if my room code was N3PV, I would tweet this: "@idarbwire #N3PV #achievement". Shortly after this happens, the achievement will unlock!
I should also add that if the achievement does not unlock for either method after following the steps, try exiting the whole game/app and starting it up again. Some people have informed me that it did the trick! Also, since the game is now officially available and many people are on it, the Twitch and Twitter feeds may have some issues so if it doesn't work, try again later. Both methods have been tested though and the achievement can be earned either way.
Anyway, VERY cool and innovative integration of Twitch & Twitter throughout this game and specifically this achievement!
