Greetings fellow Mechwarriors
I am Kodiak Jorgensson, I'm a long time BT fan and a 3D artist
I've been working on this model for sometime, I have re-worked it more times than I can count but its pretty much done. I have some Lore to go with the art work which is a bit long.

With the onset of the clan invasion Hanse Davion and his military advisors were studying the tactics and equipment deployed by clan forces. Taking note of the clans firepower packed into lighter chassis Hanse created a new fund for the New Avalon Institute of Science with orders to improve current Inner Sphere Technologies. Amanda Church is a Scientist and recent graduate from NAIS, who was put in charge of the project she had a love for Arthurian lore which lead to the creation of the NAIS Merlin facility located on the recently re-discovered planet of Merlin. The planet is a closely guarded secret of House Davion and only the highest ranks know of its existence. This facility would become responsible for the creation of the experimental battlemech codenamed ART-0X-X Arthur. The New experimental mech fielded several new technologies among these was the Class 5 Light Autocannon, this weapon has shown promise though it would suffer ammo feed issues causing the weapon to jam and destroy itself as well as the arm actuator it was mounted on. The mech also mounted the first Inner Sphere ER Medium Laser, however this was a completely different version from the one that was developed later. The X-ER Medium Laser was designed to mimic the clans ER Medium Laser damage profile, however this would lead to severe issues such as the focusing lens burning out after several shots or the weapon flooding the mech with excess heat. Though the primary weapons had issues the Targeting Computer that tied the lasers and Light AC together operated as expected, though there were a few glitches in the system to be ironed out. The First Prince and his advisors were impressed with the progress the team had made they decided to increase funding and continue the program
The ART-0X-X carries some of the most exotic experimental equipment never seen outside the highest ranks of the AFFC. The Arthur was built around a 220 XL Engine and utilizing an Endo Steel structure to save as much weight as possible. NAIS scientists realised that the mech was lacking internal space so they began working on compacting the size of a standard gyro, this led to the first experimental Compact Gyro. For offensive firepower the mech carries a trio of X-ER Medium Lasers, these lasers mimic the damage output of a clan ER Medium lasers, however they are prone to burning out the focusing lens or flooding the mech with excess heat. The mech also carries a pair of Light Autocannon 5 these weapons are prone to ammo feed issues and can lead to catastrophic damage to the weapon or the mechs actuators. Despite these drawbacks these five weapons are linked to an experimental targeting computer which has proven to be highly effective with few gremlins to be worked out, the mech has been rounded out with a single Artemis linked LRM 15. Finally the Arthur has one last secret, the AFFC military advisors criticised the mech for not having CASE protection, but due to its unique construction method the team explained that the mech does indeed carry a CASE system which has been integrated into the mechs armour thus removing the requirement to take up critical space or weight
The Arthur has not yet been mass produced and has yet to see any significant deployment, however the mech has been through rigorous combat trials where it has performed above expectations for the AFFC officers, development of the mech and its experimental weapons continue as of 3055

Thanks for viewing, hope you guys liked my art work and lore, if anyone is interested in a closer look at the 3D model you can view it on my Sketchfab page linked below.
