One of the more popular grenades, it is very lethal when thrown accurately. It is best to throw the grenade directly at the floor in front of the enemy, as you will be guaranteed a kill. Even if the blast doesn't directly kill your enemy, it will disorient and slow them down, giving you time to rush in and take the kill. Being a grenade that detonates upon impact, caution must be taken, as striking a foe or a wall too close to you will result in stunning yourself, or even worse, a premature suicide. This grenade acts like a more powerful stun grenade, albeit with a lower stun time and lower stun effect.
The Concussion grenade in Modern Combat 5: Blackout no longer explodes on impact. After the timer expires, the grenade instantly deals enough damage to kill anyone standing in the blast center, and severely damage anyone within 3 meters.
After Impact grenades were downgraded in an update by Gameloft, concussion grenades are now the most popular grenade in multiplayer due to their lethal capabilities, capable of instantly killing opponents close to the blast radius easier than other grenades.
