|Wikipedia has an article about Rocket launcher.|
The rocket launcher is a weapon that launches a rocket-propelled projectile. Originally, it was to be a hidden bonus weapon in Carnivores 2, as stated in a Carnivores 2 press release, but for unknown reasons the weapon never made it into the released game. The rocket launcher may have been planned as far back as Carnivores; a file named "EXPLO.CAR" is located in the Carnivores HUNTDAT directory. While the skin is similar to the shotgun's, there's also some odd explosion material. Unfortunately, this cannot be confirmed as the actual rocket launcher because the model was completely removed from the .CAR file at some point in Carnivores' development.
