TNA iMPACT!

This achievement is most easily done locally with four controllers.

Under Exhibition you should find the option to have a tag team match. Select your player to be Alex Shelley, and your partner to be Chris Sabin. Have the other controllers be anyone.

As soon as the match starts, start doing moves to your opponent that will cause them to lay on the ground. Once on the ground, step to their side and press B. This will go for a pin. Since all characters are controlled by players, no one will break up the pin, and you should have this acheivement in under 30 seconds.

Only the person making the pin will get the achievement, as it unlocked under my second profile, but not my first, so I had to do a rematch and make the pin myself.

Head to a tag match and select Alex Shelley and Chris Sabin as your tag team, you can choose any other two characters as your opponents.

Defeat your opponents and the achievement will unlock. You can assign your opponents to a second controller or fight against the CPU it is your choice, but be aware that the CPU will take control of the second character either way so watch out for him breaking up a pin.
