Grenade launchers in science fiction are frequently modified to fit the unique settings of the genre. They can be integrated with other technologies, like being part of a multi - weapon system on a spaceship or a mecha. In some stories, the grenades themselves can be programmable, allowing the user to set the detonation time or type of explosion precisely. This gives the weapon more versatility compared to traditional grenade launchers. Also, the appearance of these grenade launchers may be more stylized, with glowing parts or unique markings to make them stand out as a piece of advanced weaponry.
