Deathrow Cheats

You probably already know that there is 2 player mode but maybe you
don't so what you do is start a conquest or just do a singles match with
a buddy and pick your teams then it will show 2 controllers and you and
your buddy can be on the same team or you and your buddy can be on
separate teams but you would think you would want to be on the some team
on conquest but I think you would have to be on the same team anyways on
conquest
 

As soon as you start, run a little bit, then press L + B to slide or L + A to jump into the disc.
