Ch.5- The Chief has gone mad
When the group got back to head quarters, the Commander took Shmalo to a room for examination. He was walking toward the bomb when he slipped and a old microchip broke into his body. The microchip was lying on the floor and the Master Chief didn't know what it did.
He was about to grab Shmalo when he had a weird feeling and wanted to steal the bomb and use it against the Marines. Then he didn't. Then he did. The Master Chief knew it had to do something with the microchip that had entered him. With that he pulled it out but it was too late. He already had a plasma rifle out and was pulling the trigger. There was a massive explosion throughout the World. The world was almost completely gone.
There was one person living and that was the Master Chief. The microchip must have had extra strength and armor. He would live on.
