The Mobile Mine is an attachment featured for the first time in Killzone: Shadow Fall. It is a variant of the Helghast version of the underslung, HE Grenade attachment, which fires a small Spider Mine, as opposed to the normal high-explosive grenade. It is available only for the Support class in multiplayer. The Mobile Mine attachment does not carry any additional rounds in reserve, making it a single-shot weapon unless the player resupplies. Only the StA4 and StA59B of the Support class can be equipped with the Mobile Mine attachment.
