"Outgoing Stim Grenade."
Damon Baird, throwing a Stim-Gas Grenade

The Stim-Gas Grenade, Stim Grenade, or Revive Grenade is a healing grenade that releases a blue cloud of gas called Stim, that has the ability to heal or revive teammates for a short period of time. Only gibbing attacks, such as Frag Grenades and close range shotgun kills, or headshots will kill a player standing in the stim cloud.


Stim-Gas Grenades were used prominently by COG Medics and the Onyx Guard as part of their weapons arsenal.[3]



In the multiplayer modes OverRun and Survival, the COG Medic class has a Stim-Gas Grenade as its special ability, and as such, it must recharge after each use. Injured allies can be healed and any ally that was killed with a non-gib attack can be revived by throwing a stim grenade near them. Keep in mind that dead allies automatically respawn after 10 seconds if not revived.


In other Versus modes that allow stim grenades, the gas cloud dissipates much earlier than in campaign or OverRun/Survival. Also, a stim grenade thrown by a player on the red team will release a red cloud, making it easy to differentiate between friendly and enemy stim gas.

On Gears Tactics, Stim Grenades return with its functions intact. They also serve a crucial plot point as a container to house and create Cytostatic Gas Grenades.

Revive Grenades using a temporary updated Stim-Gas Grenade model in Gears 5.

Behind the scenes[]

  • The Stim-Gas Grenade made its debut in Gears of War: Judgment multiplayer as a selectable load out grenade.
  • The Stim-Gas Grenades were added to Gears 5 as Revive Grenades during Operation 8 as a prototype weapon that was never fully codevelop but added in as an extra PvP weapon. The Revive Grenades can only revive DBNO allies, it cannot constantly heal players like the version seen in Judgment.[4]
