The Impact Blaster is a combo weapon found in only Dead Rising 2: Case West. It is made by combining an Impact Hammer with a Blast Frequency Gun. The combo card is obtained by Chuck after leveling up, but it can be created and utilized by Frank. Nevertheless, Chuck is the only one who can perform this weapon's heavy attack. The Impact Blaster is probably one of the best melee weapons in the game, capable of killing anything short of a hazard unit or psychopath in just one hit.
Primary: Tap to make Chuck or Frank slam the smashing end of the hammer into a target. The force of the hammer combined with the sonic boost of the BFG will send the target flying through the air like a paper doll to its inevitable demise. Hazard Units take about 3 hits to kill and will not go flying when hit, but they will be momentarily stunned for a few seconds after being struck, giving you enough time to land another attack before they can fully recover.
Heavy: Hold to make Chuck (and only Chuck) slam the hammer directly into the ground. This will send out a massive shockwave which will kill any zombies within its range. Only an instant kill attack on zombies not people.
