The High-Explosive Grenade is a type of Weapon in SCP: Secret Laboratory. It is a throwable explosive device used to deal damage to opponents within its blast radius.


The High-Explosive Grenade can be thrown a long distance by pressing Left Click.png Left Click, or a shorter distance by pressing Right Click.png Right Click.

After throwing, the High-Explosive Grenade has a timer of five seconds before detonation. Players damaged by the High-Explosive Grenade will be given both the Burned Increases the damage the player takes and Concussed Causes the players screen to get blurry when they turn Status Effects. The time these effects last depends on range, with point blank range being ten seconds.

By holding down Left Click.png Left Click and not releasing it, the player will not toss the High-Explosive Grenade and keep holding onto it, allowing the player to aim and better time their grenade toss. It is important to note that this will not cook the grenade as the five second fuse only starts once thrown. Killing a player who is currently aiming a High-Explosive Grenade will cause it to fall to the ground and start its fuse as its pin has been pulled.

The maximum damage a High-Explosive Grenade can deal is 750. Its range is fairly small, as being 1.5 meters (2 Hubes; approximately the size of an elevator) away will reduce damage to 300.

Doors and walls block off all damage from the High-Explosive Grenade. However, most doors will get destroyed if a High-Explosive Grenade explodes near them (the exceptions are checkpoint doors, gates, elevators, SCP-106's Containment Chamber door and any door on the Surface).

The High-Explosive Grenade's blast can also push other items and set off other High-Explosive Grenades, which could, in some situations, cause a chain-reaction of multiple High-Explosive Grenades going off (simultaneously).

High-Explosive Grenades are highly lethal to SCPs. They are one of two weapons, the other being the Micro H.I.D., to ignore SCP-106's damage resistance.

By pressing R before the grenade is thrown, the player will reinsert the pin, cancelling the throw.

Server Config[edit]

There are two config options that control a multiplier for how much damage High Explosive Grenades deal to SCPs as well as the damage they deal to humans. Server owners can edit the config to change the damage multiplier on their server.
Interestingly, by default, the High-Explosive Grenade's multiplier damage to Humans is 0.7, while for SCPs the multiplier is 1.0. This means humans have a 30% grenade damage resistance while SCPs do not. Despite this, High-Explosive Grenade will one shot humans most of the time.

There are two config options to set a limit on High-Explosive Grenade chain-reactions. One allows to set a limit of how many High-Explosive Grenades on the ground can be set off by another High-Explosive Grenade (10 by default). The other option sets a limit on how long the chain-reaction can be; by default this is four.
