|Combo Weapon||World's Most Dangerous Trick|
Chuck can shoot fireworks at enemies at a relatively fast rate, clearing hordes of zombies with a short burst. Getting stuck in an explosion causes Chuck to drop the weapon.
The Rocket Launcher has a small advantage over most other heavy weapons in that it has no motor that requires starting before it can be used, Chuck can simply pick it up and start firing.
- This weapon is one of 7 weapons which a player cannot have more than one. If a player is carrying this weapon, the weapon will not respawn anywhere, prohibiting the player from carrying another one. The 7 weapons are: Magician Sword, Shopping Valuables, Giant Pink Chainsaw, Rocket Launcher (from World's Most Dangerous Trick), Six Shooter, and the M249 (LMG). All magazines also have this restriction.
- In Off the Record, Reed Wallbeck must be defeated in Story Mode to get the combo card. Defeating him in Sandbox mode will not award the player with the card if they do not have it.
- Like the rocket launcher, in Off the Record there are two Snowball Cannons: a combo weapon and a mission reward Snowball Cannon for completing the side mission Snow Job.
- In the PC game file items.txt the mission reward launcher is refered to as FireworksBazooka_reward (Fireworks Bazooka reward)
