The Dynameat is similar to the pipe bomb from the Left 4 Dead series, or the Monkey Bomb from the Zombies mode of Call of Duty: World at War and Call of Duty: Black Ops; all of which are improvised explosives that attract nearby zombies.
The ingredients for Dynameat can be found in Fortune Park, in a Maintenance room next to the Atlantica Casino entrance.
Dynameat has one of the highest potential PP yields in the game. A single piece, detonated in the middle of a large crowd of zombies, can obliterate 30 or more of them. Each kill will yield 1,000 PP, more if the player is holding one or more Combat magazines.
