This bizarre Mech was built as a test bed for research into XXL engine shielding materials. Although there are no real practical applications for such a design the scientists wanted the largest possible engine size to explore the limits of the new materials being tested.

The design is little more than a walking engine, not even mounting any armour, just covered in lightweight bodywork with so many large access panels to make any engineer envious. The only outstanding feature is the massive 475-rated engine, which weighs an incredible 81 tonnes, more than most Battlemechs! Despite its large size the MTP is capable of reaching almost 100 kph with its triple strength myomer activated, coupled with the jump packs mounted the scientists are able to place a varying degree of stresses on the engine shielding as would be experienced by a Battlemech in combat. The small cockpit can best be described as functional, but it came equipped with a variable range targeting computer (A remnant from the prototype Locust from which the cockpit was borrowed) which is wasted on the MTP, which only mounts a salvaged Clan ER Micro Laser. This tiny weapon is used by the Mechwarriors as an aid in managing heat levels to keep the TSM at optimum performance but otherwise has no real use. The MTP has also been equipped with the latest ECM suite to help keep design and research secrets, secret.
