Ten years after the Great war's ending due to a Zombie outbreak.

A rag tag group of Unsc troops who are surviving the outbreak are attacked by a horde forcing them up the building and into an empty next door building to escape to thier warthog parked down below in the alley way. Zombies rush through the building and up the stairs attempting to gain a new meal. The survivors cross a outdoor cooking area with a marine knocking off some of the roof and nearly falling. One of the snipers throws his rifle up to the next door roof and climbs a makeshift ladder to get up so others may begin to cross before time runs out. The Pilots who crossed first begin to enter the new building with flashlights out as to avoid any unwanted attacks from the shadows. Down below a Rusted out Zombie corpse Spartan awakes and makes his way to join the growing horde of zombies to ravage the SURVIVORS. Zombies are a mix of customs and pop and swap official figs.
