Alright! This is my first ever crossover so I expect you all to be nice about it.

Warnings- language, blood, violence, zombie attacks, people killing zombies, zombies killing people, zombie killing zombie.

Disclaimers- I do not own Soul Eater or Left4Dead (I don't even have the game, I'm saving up to buy it and an Xbox thought)

Owners- I do own the idea of this story though.

"That bastard! How dare she do this!" Maka muttered as the gang headed towards the Death Room. Kid nodded equally mad.

Death had said he had found something of Medusas that we should see, Maka and Kid, still pissed at her for taking Crona back and from them.

As they entered the room they found Death not his usual happy self. It might have been because the infected were getting closer to Nevada. Majority of the two star, and three- star meisters and weapons had gone out to kill the infected and find any survivors and bring them back to Death City including the death scythes but Spirit and Marie who were stationed here in case the infection got to Death City.

"What is it father?" Kid asked and Death looked away from the TV.

"This is a video diary that Medusa did that one of the meisters looking for survivors found it. it was taken last week from the date it mentions." Death said. "I think you should all see this." He said and moved away from the TV so they could see it and pressed play.

It was in a dark room not much light, but you could see Medusa very clearly from in front of the camera. Anger filled Kid and Maka to the brim with seeing that.

Medusa began speaking. "I have been studying the infected for the past two months now." She started. "examining DNA from them and blood samples in order to create a being powerful enough to eradicate all the infected from the world."

Well at least she was working for a good goal this time that was helpful.

"I have finally done it, I created a unique infected." She said with an evil smile. "Bones strong enough that it's impossible to break. Fast healing, and the ability to have the bones regenerate and become spikes out of the body and become weapons." She said and the video went a little scratchy for a moment. "The bones of this infected is it's main weapon, after creating it by inserting the genetic material into a human test subject, the human became the only infected of this kind. I have had it bite others to see if it could create other infected like it but it seems unable to pass on the infection to others."

Well that was a relief, if all the other infected died then no fear of this one getting others infected.

"It looks nothing like an infected, no decaying skin, nothing that would make a survivor think it was a infected. The only thing that makes it look like an infected is the fang like teeth and claws." She said. "it has the hunters strength in legs, the tanks upper body strength, the chargers speed and much more, I call this new infected the Shredder because it's taken a liking to shredding anything it fights using it's bones."

"I have pit it against many infected and it's won every time, I have also found that the bones are able to change form and can reach up to ten feet at most in length. Each and every bone it can alter at its will. Its bones pierce through its body and anything in it's way to reach out of the skin as a weapon, but it seems that the body heals with such speed that the bones do no harm."

"This new infected has the intellect of from before it was an infected and the infection hasn't changed is mind to make it act like a mindless zombie for it actually understands everything I say and has full memories it would seem of it's human life. It is smart enough to read a novel and can plan out strategies and speak English. But it seems to have trouble fighting its instincts to act like an infected." Medusa said and the video was over.

"So….she made a new infected that she has under her control?" Kid asked and was wondering who this 'human test subject' was that she made into the shredder.

"She 'had' under her control, that is why I want you to see this next video, taken just two days later." He said and popped in another tape.

Medusa seemed terrified and you could hear a bloodthirsty screech in the background.

"I have lost control over the shredder. I don't know what happened but it is going on a rampage killing everything in site. It seems to be letting its infected side get the better of it. the shredder is no longer an appropriate name for it. Spike is the better term for it. It's getting smarter, it's realized it is more powerful then me and is going to prove it. for anyone who sees this video listen well." She said and her fear went up a few. "Beware of the Spike." She said but suddenly something pierce through her, somthings to be exact, there were three spikes going through her body covered in blood, they soon went back through as though someone was taking them out of her.

Medusa fell dead and you could just make out the outline of a person, the person looked up and you could see blood red eyes and a screech emitted through the being before it destroyed the camera with the bone that was protruding out of it's hand.

So that was the Spike or once known as Shredder.

"Medusas own experiment killed her and I don't think we could stop this thing. We need to get it destroyed quickly." Death said his tone serious, suddenly it was buoyant again. "Medusa was terrible at choosing names, the Spike? The Shredder? Both awful names." He said. "I want you all to go and look for it and try to capture it. Kid, Blackstar, Maka, you three are immune to the infection. Liz, Patty, Tsubaki, Soul, you should be safe in weapon form." Death said smiling and looked at Kid and Maka. "Besides you might find Crona, she was also immune to the infection so she should be safe plus she has Ragnarok so she can fight of the Infected." He said.

"We will do it." Everyone said, Kid and Maka happily for the fact they might find Crona.

Alright for those who didn't figure it out, Kid likes Crona, Maka is still pissed at losing her best friend (Crona) to Medusa So there is a slight KidXCrona in this.

I need a name for the new infected! Does anyone have any suggestions? If so please say them!

Also this is the information of the new infected name is blank cuz it has no name yet.

Name-_

Special infected

Unique one of a kind.

Can regenerate bones and bones can grow and become weapons sharp enough to cut through metal. Can jump almost as high as a hunter and is just one foot short in length it can jump compared to a hunter. Has the strength of a Tank and the speed to boot. Can use it's bones as a weapon and a shield and by seeing the solo weapons it sometimes mimics there fighting style using its bones as a weapon (Girikos sawfoot and Justins guillotine blade)

Can think like a human but has to force the instincts of the Infected down. Doesn't look like an infected and most of the time people realize it's an Infected a second to late.

Anyways please reveiew!
