|Weapon Type||Fragmentation Grenade|

HEF Grenades can be thrown by pressing "3" (By default) and has approximated fuse time of 3 seconds. They can be bounced through doorways and around corners if thrown carefully, and are powerful enough to kill weaker enemies instantly. Stronger opponents (such as Heavy Response Units and Maximum Force Responders) will usually be knocked down and often lose their helmets; this is purely aesthetic and no extra headshot damage is granted. Bulldozers and Shields will take little damage, but will be staggered and vulnerable for a second or two. Grenades cause damage to most destructible objects in the game, and can be used to complete the damage objectives of Mallcrasher. However, they will also destroy boards placed over windows and computers in the lab of Big Oil, potentially destroying a valuable clue.
The damage dealt by grenades decreases as distance from the explosion increases. At a distance of 0 meters from the explosion, enemies will take 600 damage. At a distance of 10 meters from the explosion, the damage dealt is down to 0. The formula determines the damage dealt by a grenade, where distance is the distance between an enemy and the explosion, and maxDistance is the maximum range of the explosion, 10 meters. If the enemy is wearing heavy armor, the damage is multiplied by an additional value between 0.6 and 0.7.<ref name="LongGuide>Frankelstner's "The Long Guide"</ref>
Grenades can be detonated prematurely if struck by gunfire, even from your own weapons; care should be taken if throwing them towards a group of SWAT units that are actively firing towards you. Very few things are more humiliating and painful than you and your allies taking a lot of damage because your grenade was hit by a stray bullet. Frag grenades also do damage through walls, so beware of throwing them near teammates or crowds of civilians, even if separated by a wall.
Bulldozers will always be stunned by grenade explosions and stagger backwards if they are within the 10 meter blast radius. Take advantage of this to repel incoming attackers when low on ammo. In addition, the explosion can remove his faceplate or visor, potentially exposing his face to regular damage.
Those with incredibly good aim can purposefully shoot to detonate their own grenades tactically. If capable, one can toss a frag above a group of enemies and blow it up to cause massive damage. Automatic hitscan weapons such as assault rifles, LMGs and SMGs are best suited for this role because of their high rate of fire and/or relatively good accuracy at mid-to-long ranges.
Grenades, along with other throwables except for the Shuriken, are very helpful when activating the Berserker skill. Three direct explosions usually aren't enough though, and you may need to request the help of teammates or buy a grenade case asset. If wearing a suit though, three direct explosions will be more than sufficient to get your health below 25%. Chaining explosions is the most effective method, as a lot more damage will be done once your armor has been depleted.

- The HEF grenade appears to be a modified version of the Frag Grenade, it appears black with a yellow line going across the middle, with markings describing proper usage. It also has the Overkill logo attached to the pin of the grenade. They also appear more blocky than the original and sport a different animation than the original.
- Wolf and Houston both refer to grenades as "bombs" at certain times instead of grenades (this is not necessarily wrong as grenades are a handheld type of bomb, despite not normally referred to as such), usually while throwing them, with Wolf always calling them "bomb". Dallas usually identifies them as grenades, and both Hoxton and Chains will rarely ever refer to them as such, instead making witty quotes whenever they throw one.
- If one were to try to throw too many grenades at one time, the message "SYSTEM: [Playernamehere] tried to throw too many grenades" will appear and a tag above the player's head will say "CHEATER."
- Chains' line, "Surprise, Motherfucker!" is a reference to an internet meme, where James surprises Dexter in the TV Show "Dexter", with James saying the same line.
- The ability to shoot in-game Frag Grenades to detonate them prematurely is practically implausible in reality, as most modern grenades contain a filling of mechanical shock-resistant explosive filling as per military requirements for explosives used in a combat environment. The "spark" or mechanical shock from an impacting projectile will most likely not be sufficient to initiate the explosive but would still destroy the grenade. While it is not at all impossible to shoot a live grenade in mid air (in fact some individuals were specifically trained to do so in WWI with shotguns), doing so with anything but a shotgun would require pinpoint-accuracy skills, nearly inhumanly fast reflexes and if premature detonation is desired; a firearm utilizing fairly high velocity ammunition (ie; assault rifle), all of which combined is not a very common occurrence in a combat situation.
- Hand grenades, however, also contain a detonator which is usually several inches long and about the diameter of a pencil. This detonator usually contains a more sensitive primary high explosive that can be initiated by a flame from the delay fuse. In theory, if a projectile was able to penetrate the steel casing of the grenade, pass through the explosive filler and then strike the detonator, the grenade could detonate. The chances of this occurring, however, would be unlikely given all of the circumstances that would have to be met.
