The MJR-409 (RPG-7) is basicaly the rocket launcher from Goldeneye 64 updated for the Wii version. The rockets fly in a straight path and explode on contact with an object or player. It isn't available on online multiplayer but it does appear on a few multiplayer levels.
Trivia
- In Goldeneye 007 Reloaded, it is the most useless weapon in existence. It appears only in the Solar power plant level, near to the lift down to the server control area and comes with just one grenade. This is likely an Easter Egg as there isn't any additional grenades to keep using it.
- The weapon appears in the Solar Assault Mi6 Ops mission twice, used for destroying a helicopter. It comes with additional grenades, but if all supplies are used up, the mission cannot be completed. It is best to play the mission with unlimited ammo enabled.
