Also, there is a ' Clash' system in place. For example, players can actually see injured players take damage inside their body. However, in this installment, the violence is more prominent. Like previous games in the series, the first down is earned with 30 yards instead of the ten in real life NFL football. Blitz: The League is very similar to previous installments in the NFL Blitz series, as it depicts an aggressive and violent version of gridiron football.
