Ultimate Blitz is a survival game mode depicted as a blood sport arena. It is played in a very small, circular stage. Your team walks in through the aisle, onto the stage, and it ascends through 50 floors. For each floor, there are 2 waves of enemies to defeat before the boss makes its appearance.
There are 3 difficulty levels (Normal, Epic, Legend), totaling at 150 rounds playable throughout the span of a month. Ultimate Blitz is unlocked after finishing the story campaign on normal difficulty.
