Playoff Blitz is the 3rd Blitz mode, and lasts for 30 rounds. The game shows the intensity as "Heavy." This can be played either solo, split-screen co-op, or co-op online. I was able to fairly easily complete it solo as the Support character.
Some tips: watch the green lines on the ground as they indicate where the waves of bots will be coming from. Some mid and later waves will come from the sides and behind, so don't focus all of your attention on the front. Later on "Gap-Shot" bots will come from the front spawn areas and send mortars in from long range - these stay out of the range all all towers and must be dealt with manually or with a well placed Fire Base (as Support) or Hack/upgraded towers on the front tower locations. Focus on keeping your turrets at max health and slowly build up more turrets and your own skills.
