The LS13 Shotgun (nicknamed "Lucky Strike"), also known as the M13 Semi-Automatic Shotgun, is an ISA weapon that fires a dense cloud of pellets with every shot, as all shotguns do. It is manufactured by the ISA, but is more commonly found in helghast hands. The LS13 is one of the most efficient weapons in the game, allowing for multiple kills before requiring a reload. It is lethal at close range, but is also useful at medium range. It is ineffective at long range, leaving the unwary shotgunner exposed to long range weapons. In Killzone 2, Natko carries one of these weapons.
