Stun grenade

The stun grenade is a type of UNSC grenade which produces an electromagnetic pulse which temporarily immobilizes targets for several seconds. The grenade was utilized by Spartans during the Battle of Installation 03 and the Battle of New Phoenix.

Gameplay
When used, the stun grenade temporarily stuns all hostiles and allies within the effective radius for approximately four seconds. The stun grenade effect replaces the stun blast armor ability which appeared in Halo: Spartan Assault. The grenade has the advantage that it does not require any cool down and recharge time between uses. The disadvantage is that unlike the armor ability - which can be used an unlimited number of times - each grenade can only be used once; it also takes up one the player's valuable grenade slots. The stun grenade is particularly useful when surrounded by enemies, or when attempting to defend an area or asset from an onslaught of enemies.

Halo: Spartan Strike also features the Stun Grenade, but allies are no longer affected by it.
