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

The High-Explosive Grenade can be thrown a long distance by pressing Left Click, or a shorter distance by pressing 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 the Burned Increases the damage the player takes, Concussed Causes the players screen to get blurry when they turn and Deafen Effect Makes all noises muffled and quiet for a short time Status Effects. The time these effects last depends on range, with point blank range being 15 seconds for Burned, and eight seconds for Concussed and Deafen.

By holding down 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 3.5 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.

Wearing Armor will reduce the amount of damage taken. Grenade damage is unaffected by the armor both SCP-049 and SCP-173 have. Grenades have a penetration of 50%.

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, and elevators). The ability to destroy doors make them extremely effective at countering SCP-079.

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.



The following chart represents the max damage a Human player can receive from the High-Explosive Grenade. Additionally, these stats are the same for other explosions such as: Jailbird, Pink Candy, SCP-018 and mixing SCP-207/SCP-207?. The explosion of the 3-X Particle Disruptor has unique stats.

No Armor Light Armor Combat Armor Heavy Armor
Penetration 50% 50% 50% 50%
Body (100%) 300 240 210 180
Burned (125%) 375 300 262.5 225
Purple Candy (80%) 240 192 168 144

The maximum damage a High-Explosive Grenade can deal is 900 to SCPs, with a base damage of 300 to humans. The damage is cut in half around four meters away. The explosion will deal double the amount of damage to Hume Shield. If the double damage is enough to completely destroy Hume Shield. The remaining damage will be dealt to the SCP's normal health but will no longer be doubled.
For a more detailed example, SCP-106 starts with 350 Hume Shield. If SCP-106 takes the max 900 damage from the explosion, then 175 damage of that 900 will be applied to their Hume Shield. That 175 is then doubled to become 350, destroying SCP-106's Hume Shield. The damage SCP-106 takes to their normal HP would be 900-175. Which equals 725 damage.
