If you pick a wrestler and go to the side of the ring,go as close to the ring as possible and if you press R1 your wrestler should pick out a weapon.

Here are what side of the ring the wepons are on:-
Top-Table
Bottom-Sledge hammer
Left-Chair
Right-Chair

But if you want the speacial weapon (ladder) you have be a certain wrestler.This only works with some people.
You have to play with one of the following characters:-
1-Rob Van Dam
2-Jeff Hardy

I think it also works with Edge and Shawn Michaels
you will have to try it.

If you read the top part where it says which side of the ring the weapon is on the right hand side there is a chair well if you be one of these special wrestlers the chair will be replaced by a ladder. and also if you try to get a table in a TLC match you will pull out a trash can lid instead that works with any wrestler, and by the way if you think this is a bogus hint then try it out and if you play the game 24/7 like me and you will find out in a DQ match the computer pulls out weapons aswell.
