"Wrist fired grenade that will detonate on targets."
Create-A-Class description.

The XM31 Grenade is a Lethal Grenade in the campaign of Call of Duty: Black Ops II. It is a wrist-mounted grenade launcher that is used by J-SOC soldiers, and fired from the Data Glove Paired.


It works similar as regular grenades but explodes on impact if an enemy is hit. It can be unlocked in the customize class menu. The grenade can not be cooked and the action may be cancelled by pressing the weapon-swap button/scrolling mouse wheel. Another added benefit is that the trajectory of impact is shown on the HUD which can occasionally be useful. In the main campaign levels, only Fragmentation grenades may be fired but in various Strike Force missions, Semtex grenades may also be fired. These grenades are part of the recommended loadout for all future levels. The XM31 Grenades cannot be refilled with the Ammo Pickup Perk; they can only be refilled with ammo boxes, which means that the players should use these grenades only against large groups of enemies or against ASDs, CLAWs and sentry turrets. In Fallen Angel, Section and Harper use a rope from the XM31.



  • Whenever Harper uses his XM31, he doesn't pull the trigger, but can still fire.
