MESS-S1cC-015 Jupiter

Technology and Combat Characteristics
The Jupiter was designed around the use of the Sub-Arm Units: an extra pair of arms that were almost identically designed like the unit's main arms. They were attached on two back-mounted booster units, which could fold out from the boosters when activated. Since the amount of controls needed to operate all four arms at once was not possible at the time, a second "gunner" pilot seat was installed in the Jupiter to control the sub-arms. This required the pilots to have a good amount of coordination when in battle.

Armaments
- 30mm Shoulder Vulcans: Due to the Jupiter's primarily unarmed fighting style, these 30mm shoulder vulcans are used as a suppression weapon to stall enemy units. With a low damage output and similarly average rate of fire, they are best used to target camera and joint systems on enemy machines.

Special Equipment and Features
- Advanced Sub-Arms: This extra pair of arms can perform a number of actions, from holding weapons to using melee attacks. They are operated by a secondary pilot under the Joystick Control System, who sits above the METACOM using-pilot's cockpit.

Trivia
- The Jupiter bears a striking resemblance to the MESS IV of the Epic Yoshi Comix universe, with both units using a four-armed design, as well as needing multiple pilots in order to operate. - It is also a “Shiphead” like its successor, the Jupiter II.
