Solid State Machine is an action-stealth tabletop RPG and one of the six games in the MemoryCore anthology, inspired by the tactical espionage and mind-bending storytelling of Metal Gear Solid.

You are the Vesper Squad, an elite infiltration unit sent to Ark-9, an Arctic research platform seized by the Ghost Guard: former Vespers gone rogue under the command of the legendary Old Root. They have made no demands and issued no threats. Your mission is to infiltrate the facility, uncover what happened, and stop them before the situation spirals out of control.

Stealth, action, espionage, impossible conspiracies and, inevitably, cardboard boxes.
