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.

In Game[edit]

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.

Once thrown, the High-Explosive Grenade has a timer of 3.5 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 900 to SCPs, with a base damage of 300 to humans. Its range is fairly small, as being 1.5 meters (2 Hubes; approximately the size of an elevator) away will reduce damage a lot. The explosion will deal double the amount of damage to Hume Shield. Wearing Armor will reduce the amount of damage taken.

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. The ability to destroy doors make them extremely effect at countering SCP-079 as they can not Blackout any room that has a destroyed door.

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).

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

High-Explosive Grenade are also capable of destroying instances of SCP-244 and Tantrum Puddles left behind by SCP-173.
