The frag grenade is an explosive hand-held bomb possibly left behind by a soldier during an unknown time period. It can be equipped by the player and thrown, causing an explosion that will damage the surrounding terrain after a few seconds.
Accidental drops or intentional attempts to injure oneself will not be effective; currently, frag grenades do not harm the player in any way, rather only causing them to bounce if they are caught standing directly within the blast radius.
As it is an unofficial addition to the game, the frag grenade can only be obtained through modding. Whether the explosive will officially be implemented in the game has yet to be announced. Should it be added to the game, it is speculated that frag grenades will be found hidden inside plane wrecks or washed-up crates.
- Due to its current state as an unofficial Stranded Deep obtainable, the frag grenade is treated as an Easter egg item, its description displaying the same "Awesome" tag as the regular Easter egg items.
