Def Jam: Vendetta Cheats

Choose Spider as your character. Grapple (A) and then press A + up or A
+ down (after this move the opponent should be on the floor with their
legs facing you). When they are on the floor press A and you will do a
move which damages their leg health. When the move ends and the
opponent gets on to his feet repeat the process (grapple, then A + up
or A + down the A when the opponent is on the floor).

When you fight Pockets, House, and Snowman, beat on one of them. Then, run away and work on one opponent at a time. When one of them is in danger, use your Blazin against him and you will automatically K.O. that person and win the match. Remember, keep running.
