Stun blast

The stun blast is a piece of UNSC technology. It is an armor ability with effects similar to those of a power drain. It was utilized by SPARTANs Palmer and Davis during the Battle of Draetheus V.

Gameplay
When used, all hostiles and allies in the area will be temporarily stunned, for approximately four seconds. After each use, it takes around five seconds to cool down and recharge. The stun blast is particularly useful when surrounded by enemies. Players must use the stun blast at least once, to earn the Powered by MJOLNIR achievement. In Halo: Spartan Strike it is replaced by the largely-identical stun grenade.
