The Genetic Lifeform and Disc Operating System. Why? Shut it down,and there's a good chane a rogue Personality A.I. will come along and turn it back on. the system ALREADY went through extreme trauma as it is in the first defeat,coupled with several years of damage caused by Mother Nature. The cords and casing are OBVIOUSLY made up of a diamond/adamantium alloy. Furthermore,becaue it's a supercomputer with full control of an entire facility with access to semi-sentient turrets,and a special particle barrier system that can and WILL vaporize the things the system doesn't want you to have,while cutting all connections to whatever you had in the are beforehand. And,in the off chance you reach the core of the system,you will be exposed to a potent neurotoxin. The system's only weakness is the missiles that are fired from the turrets,which disengage one module that must then be disposed of in order to re-engage the turret you need. This process,howeverwill only lead to a shutdown. And the process begins again,with Propultion and Repulsion Gel,Areal Faith Plates,Thermal Discouragement Beams and Weighted Storage/Beam Reflector Cubes and Escursion Ducts. That and a few more obstacles...
