Weapon LoadoutsEdit


  • Using the Pistol Ammo Mutation mod can help regain lost ammo when needed. Alternatively, use Pistol Scavenger aura or bring along Team Ammo Restore.
  • Using short bursts of fire greatly improves accuracy and makes the weapon viable at medium medium-long distances, although it is still advised to be used at close quarters.


  • The Twin Vipers were released on April 12, 2013 with Hotfix 7.7.3.


  • When used with the Atlas Warframe and summoning Rumblers, the weapons switch to single shot fire and after each shot the weapons show the Landslide ability animation and sound effect.
