Irish whip your opponent on the right hand corner (turnbuckle) of the
ring and run towards him and press X so your superstar performs a move.
If it hits your opponent right on the chest, you will see the chain from
the turnbuckle cushion fall down and then you can use it. But be to hit
him on the chest. If you hit him somewhere else, it wont work.

You will get DQ'd if you use the chain but its really fun so go ahead
and try it.
