As the Jihad rages through the Inner Sphere many people flee from their homes in search for safety. Many of them end up in the Magistracy of Canopus. The refugees that flee to the MoC are mostly women. One of these refugees is Boudicca Guderian.
     She is a wealthy engineer who had worked on reintroducing the Starslayer Battlemech. During the Jihad she had lost her husband and her children to the WOB. She managed to flee with a large weapon shipment that were about to be used for an upgraded Starslayer, containing ECM equipment, TSM bundles and extended range lasers.
     At first she worked the MoC to upgrade their Starslayers, but a large amount of equipment remained after upgrading them. Boudicca then had the idea to use the remaining equipment to create a command 'Mech. However the government didn't share her enthusiasm about this assault Mech project, and thus didn't give her any of the normal subsidies.

     Without the subsidies Boudicca was unable to buy the necessary fusion engines. This forced her to use an internal combustion engine with power amplifiers to support the gauss weapons and the lasers.
     The Planetslayer is based upon the Starslayer and this can be clearly seen in the looks. Like with the Starslayer the main punch comes from two main weapons mounted in the right torso and arm. Both in this case are gauss rifles. Triple strength myomer were used to compensate for the slow engine. The rear facing extended range medium lasers and the ECM suite are used to cover the weaknesses of this mech. The twelve rocket launcher packs were added to give the enemy a reason to keep away.

     Even with all the effort that is put into this project, only one or two Planetslayers are manufactured every month. Nevertheless the military is happy with the design and is deploying them as a fire support 'Mechs in the Magistracy Royal Guards. With the growing support from the military, Boudicca should have enough support to ask for subsidies needed to make a larger production run with fusion engines.
