Jimmy, Cindy, and Libby slowly made their way down the winding hallways. Jimmy put his arm out and stopped them as he squinted his eyes and looked ahead. "That door, it doesn't have one of those metal plates on it. Maybe we can open it," Jimmy whispered. The girls nodded their heads as they continued walking.

Just then the phone rang again. An agitated Jimmy answered it. "What is it now?"

"Yes, the door ahead of you is unlocked," the voice said. The three friends started running towards it. "STOP!" the voice yelled. They all froze. "You have a choice. You can exit the school right now and leave this hell, or you can save your friends."

"What do you mean?" Jimmy nervously asked.

"Well, let's just say they're going to have a blast," the voice said before hanging up.

Cindy, Libby, and Jimmy stared at each other. "You guys go. I'll take care of him," Jimmy said before running off.

"We're doing this together!" Cindy shouted as she and Libby tried to keep up.

As they rounded a corner the killer jumped out from the shadows and stabbed Libby in the leg.

"Ow, my leg!" Libby yelled as she fell to the ground. Jimmy and Cindy turned around and tackled the killer.

Jimmy punched the killer in the face while Cindy pinned his arms to the ground. The killer just kicked Jimmy off of him and turned towards Cindy. She stood up and tried to kick him in the face, but he blocked it and grabbed her foot. She screamed as he twisted her ankle. Jimmy came up behind him and tried to hit him over the head with his backpack, but the killer spun around and kicked him in the stomach. He turned back around and faced Cindy. He kicked her across the face, which sent her flying across the floor.

Jimmy and Cindy lay at the other end of the hallway, dazed and barely conscious. Libby tried to crawl away as the killer approached her. She laid down on the ground, clutching her leg.

The killer unsheathed a knife with one hand and took out his mechanical device with the other. Libby stared up at him. "This is one hell of a game."

The killer pressed a button on the device. A distorted voice came out. "You lose," it said while the killer thrust his knife down at Libby.

Libby rolled out of the way and quickly stood up, ignoring the searing pain in her right leg. The killer pulled his knife out of the floor and turned to face her. He swung the knife at Libby, but she jumped backwards.

"I AM NOT A DAMSEL IN DISTRESS!" she yelled while punching him in the face. He staggered back and clutched his head. He ducked as Libby swung at him. He punched her in the stomach. She blocked his next punch and tried to twist his wrist, but he slashed her arm with the knife.

She fell to the ground, clutching her arm. Just as the killer was about to finish her Jimmy ran across the hallway and hit him in the face. As the killer went after Jimmy, Libby slowly walked over and slammed a heavy book across his face. Jimmy and her took a few steps back and Jimmy pulled out his knife as the killer also backed away. He pulled out his voice machine again. "Boom," it said. Suddenly a loud explosion occured a few hallways down.

Jimmy and Libby spun around. When they turned back the killer was already gone. they ran to the other end of the hallway and woke up Cindy.
