Tactical Information

  • The Grenade Pistol is a very useful utility secondary weapon, as it is the only weapon in its class that can inflict explosive damage.
    • In particular, when used properly it is capable of destroying Terminid Nests and Automaton Fabricators, allowing the wielder to equip a different type of grenade such as G-23 Stun while retaining the ability to destroy enemy spawners.
    • The explosive and splash nature of the grenades allows the Grenade Pistol to dispatch multiple enemies with a single shot, or inflict significant Structural damage to large body parts such as the thorax of Bile Spewers.
  • Because of its significant falling arc, it can be very difficult to land precise shots at long distances since gravity must be accounted for. Be sure to practice in order to get used to the arc.
  • This weapon's greatest drawback is that it is extremely ammo-inefficient. When picking up supplies from a Resupply or B-1 Supply Pack only two grenades will be replenished, and when picking up an Ammo Box only one grenade will be replenished; Grenade Cases do not replenish the Grenade Pistol. Be sure to balance grenade consumption with that of the primary and support weapons.
  • Be careful when firing the Grenade Pistol at very close range, as the fuse has a range safety that prevents it from detonating too close to the wielder. If the grenade hits an enemy at point-blank range, it will simply bounce off and ricochet, exploding far from its intended target.
  • The One Handed trait means that the Grenade Pistol can be used while holding items like the SSSD Hard Drive or while wielding the Ballistic Shield, and it will be automatically equipped in these cases if no other weapons with One Handed are equipped.



Target Hits Notes
