The MSR I - Chainsaw v3.0 was the third version of the spider-like MSR I - Chainsaw Model. The Chainsaw v3.0 was first found fighting at the Joba MegaCorp Games and later protecting the Thugs-4-Less prison. Stronger and tougher than the previous versions, unlike the v1 or v2, the v3.0 posed a significant threat with its upgraded armor and chainsaw.
