The Sisyphus is a modular, posable heavy fire support mech model designed for 120mm or larger bases at 28mm scale. The kit includes several interchangeable components, featuring two main rifle options (shotgun and anti-mech rifle), two shoulder-mounted weapons (anti-tank missile and artillery), and multiple small wrist-mounted weapons. Additional customization options include three armor sets, three cockpit covers, and an optional cockpit interior. The creator recommends scaling the model to 115 percent for use at 32mm scale.
