The Grenade Launcher is a devestating weapon in the right hands. The ability to bank rounds off surfaces means that the cover you're behind might not be as safe as you think.

The Grenade Launcher's real-world counterpart is the TGL-6

GoldenEye 007

Trivia

In Jungle after you defeat Xenia and pick up her weapons you can wield both the Grenade Launcher and RC-P90 together, this is the only time in the game where you can dual wield two different weapons without using the weapon switch bug.
