The LAPA SMG was added into Warzone as part of the Halloween Haunting event update on Tuesday. Unlocking the LAPA takes more leg work than most weapons in Warzone have, with players needing to complete 9 challenges, all in the new Ghosts of Verdansk mode, to unlock the gun. You can also unlock this gun via Cold War challenges, or by purchasing it in a COD store bundle for real money.

Here are all the challenges you need to complete to unlock this new weapon!
