Avoid PPC Projectile
To easily avoid a PPC projectile when playing on Xbox Live, choose a mech that has jump jets. While the enemy is charging up their PPC, activate your jump jets. Once they fire, release the jump jets and the PPC will fly over you as you fall to the ground. This can be very effective against Mad Cats.
