Soldier Four started to stagger as it ran in panic first towards the medics before he could hear them approaching. The infection had already began to affect the thinking of the alien. It Stopped at the entrance of the ship and began to throw it's load of grenades at the approaching horde. While each grenade that landed in a group of zombies exploded throwing bodies whole and in parts into the air it only attracted more zombies towards the soldier and the the time that Soldier Four ran out of grenades the number of zombies following the alien had grown from a dozen to hundreds and zombies had begun to attract other zombies with the noise they were making.

Still clutching its mangled hand Soldier Three ran around the side of the ship towards the entrance of the ship to collide with Soldier Four. Both Sectoids screamed in panic as they fell to the ground together in a pile. Neither realised in their panic how quickly the zombies closed in until the press of zombies stopped the door from closing.

The sound of the UFO's engines pulsating combined with the group moaning continued to draw more and more zombies into the UFO flooding the interior of the ship with invaders while at the entrance the two soldier type Sectoids were torn apart and eaten before they could die.

"Soldiers control your selves or you will be declared unstable and be destroyed." voiced the Leader through the communicators. Leader turned to the navigator "Log in the destruction of the soldiers on return as they are faulty and are showing emotions"

"It is done Leader. On return to base the surviving soldiers will be destroyed and replaced."

"Good it is clear that this batch are failures perhaps the genetic strain can be recovered."

Leader could hear something over the communicator bout could not identify the sound. The Sectoid Leader turned to the ship's remaining two crew. "Get your weapons we have human boarders."

The Engineer collect it's plasma pistol and grenades before moving over to the side room that had no floor so that some of the races that floated had easy access to the bridge from the base level. The Engineer saw that below it in the accessible hallway that it was full humans packed in tight and were still trying to come in. "Leader this is Engineer we have humans coming in the left hanger. They number over fifty. Using grenades to thin them before dropping in."

"Leader this is Navigator the humans have just managed to enter the right hanger in large numbers. They appear to be unarmed, wounded and disorientated. Using grenades."

Leader could hear the grenades exploding but something was missing. In the time it took the for the alien to ride the lift to the lower level it worked out that was was missing were the screams from the humans. wounded humans always screamed when they were wounded but above the pulsating drone of the engines idling Leader could not hear any human screams just the sound of grenades exploding.

Opening the door into the hallway Leader was surprised to see thatthe hall way was full of injured humans. With out a hit of mercy Leader aimed for the human's stomach when it fired because Leader loved the sound of humans screaming in pain. Three plasma bolts ripped into three humans but the only effect was that they turned towards Leader and reached out towards the Sectoid.

Leader backed away from the humans trying to figure out why did the humans not react to the plasma pistol. Holding down the trigger to the pistol Leader emptied the energy clip into the closest human that was dressed as a paramedic. Bolts ate into the human tearing chucks of flesh then bone away from it. A hand flew away as the wrist exploded, the opposite shoulder was first shattered by several bolts before a final bolt damaged the shoulder to badly for it to take the weight of the arm. Flesh first stretched then tore and the arm fell from the body and yet the human still advanced. The plasma pistol fell silent as the energy clip was drained. The human was serverly mangled, one arm ended in a stump, the other arm was missing. the head had taken several glancing blow the left side of the humans face was burned off the jaw was hanging on by only a few threads of flesh and swung past the shoulders. Yet the human still advanced.

Leader only realised it's mistake of concentrating on the human in front of it when it felt hands grab it's arm and pull the alien towards the other human. To the Sectoid's shock the human pulled it's hand to the humans mouth and bit into the Sectoid's flesh. Without thinking Leader pushed the muzzle of the pistol into the forehead of the human and fired turning the skull into a pressure cooker that erupted with boiling brain punching out the rear of the skull.

Leader pulled back it's hand and saw that the bite mark left by the primitive human was only bleeding a little. "Crew report."

"Engineer here. The humans continue the advance despite the injuries the grenades have inflicted. Have used all grenades."

"Navigator here. Humans are ignoring the casualties inflicted by the grenades. Am also out of grenades."

"Cease attack and prepare for lift off we will take these humans back to be examined instead." Leader continued to back away from the humans that were now starting to pour into the room towards the lift spraying the approaching horde to little effect.

Leader back onto the lift and triggered it to alien looked at the bite mark the primitive human had made and was satisified that the wound was no longer bleeding.

Outside the UFO the engines increasing in volume only acted to draw in more of the zombie horde. The ship's doors to the outside struggled to close with zombies blocking the door. As the ship rose zombies tumbled from the ship until the doors could close and seal.

Navigator sat at the controls "Leader the autopilot back to base has been set we shall be back at the base on the dark side of the moon within the hour."

When Leader did not respond Navigator turned to face the superiour Sectoid who was standing over the alien. The Sectoid did not expect Leader to grab its face and bite into it. The alien screamed and began to try and fight off the attack. In moments the engineer was trying to pull Leader away and succeded only to have the infected alien now facing it.

Shocked at seeing the blood smeared face the Sectoid froze for a moment which was enough for the zombie to lean in and tear a chunk of flesh from the Engineers throat.

While the other two were fighting Naviagtor fled the bridge to one of the side rooms to escape the attack. The bite mark burned and felt like it was melting into its face. It could feel blood pouring down it's face. The alien had almost reached the door when it was slammed into the wall and brought to the ground. It rolled over to stare into the dead eyes of its former leader and it realised that it would not live to reach the base but that this load of humans were infected with something dangerous to the Race. The only course it could take was to overload the engines and destroy the ship.

Navigator managed to push the snapping Leader off itself and ran past the dead Engineer to the control board to start the self destruct procedures. Without warning it was pulled to its knees. looking around it saw Engineer had grabbed it's leg and was pulling it towards the set of hungry teeth of the engineer. The navigator screamed as it fought off the attacking engineer only to feel another set of hands then teeth tear into it from behind.

On the dark side of the moon a UFO returned on automatic pilot to land in the hanger.

"Ship 157 report on your crew status."

"Ship 157 report on your crew status."

"It looks like all crew on 157 are dead. send in a cleanup crew then ready it for launch."

"This is ground crew to command we have humans leaving Ship 157. Moving it with stun guns to capture the humans."
