Concussion grenade (DXHR)

Concussion grenades are a weapon in the upcoming videogame Deus Ex: Human Revolution. Unlike their equivalents in Deus Ex: Invisible War, which provided lethal damage to organic targets and inorganic ones alike, Concussion grenades in Human Revolution serve a different purpose. They now closely resemble stun grenades, weapons used to incapacitate people without killing them through loud noises and bright light. They can be used to great effect in non-lethal runs, but they are not stealthy, as the noise and light the grenade emits can be easily detected by enemies. As with all other grenades, the player must be careful not to catch themselves in the blast radius.
