Deformers

This was a bit of a hassle due to no one playing the game anymore. I loaded up a second controller then went to the opening menu and selected play All you have to do then is select any of the game modes available. I had to wait for several minutes until someone else came in, but while I was waiting, I clicked X on both controllers so I was ready to go until someone joined. After they jointed, we played the round. After the round the achievement popped.
