The IRL-1, or Infantry Rocket Launcher - Mark I, is one of the latest weapons created by Keats' Firearms in 2039.
Origin
The IRL-1 was created when Richard Keats had the idea to create a Rocket Launcher made for taking out enemy soldiers, and not for anti-vehicle use. While it can still be used for anti-vehicler use, it is not very effective.
Effectiveness
The IRL-1 fires a volley of 3 small rockets, useful for taking out a heavily armored aponent or a row of aponents. It carries a maximum of 15 rockets at a time and is useful for a while in Nazi Zombies, but runs out of ammo quickly, so it is recommended to get a replacement from the Auto-Changer Machine as soon as possible.
