in spider man the movie game how do you get to were you wrestle in the cage?

how do you do that cage match were you fight the villans and they keep coming? is that in speacials under traning or secrect room? is there a code to get it easier? please help if you know thanks

I'm at that part in the game, give me a little while to figure it out! There has to be access to it, something I'm overlooking. It can't be that hard of an easter egg to find!

go to specials menu, choose training, then enter basic combat.....u will fight bone saw after swarms of enemies
