second player cheats

Jusenter them while in 2 player (obviously, what are you on???)

You don't need a chat to get 2 players you have to find a 2 player icon and the second player press start or select

You don't need a cheat, just walk into a 2 Player Icon and press a button on the Second Controller.

Do the cheats normally.

However the cheats don't work on player 2.
So doing a health cheat whilst in 2 player mode will only work on player 1.

You can find a 2 player icon at Denises house.

Usually health cheats don't work on second player.........but you can find an armour for second player, or enter the infinite health cheat from 1st player remote and it will get applied for both! Hope this helped!
