The Shotgun or SG is the specialist close range weapon for all Marines and occupies the Primary Weapon slot. It holds 6 cartridges at any one time and a Marine can carry a maximum of 24 extra cartridges, making for a total ammo pool of 30 rounds.
This weapon is extremely lethal at close range and when upgraded, can kill most Aliens in 2-3 shots. Because of the nature of its cartridge ammunition and spread, Marines should attempt to hit the centre-mass of Alien lifeforms (a meat-shot).
