The Awakening

All 3 of the cast wake up inside of deep sleep chambers on board what they assume to be a starship. they have no memory and are in a lot of pain. they also feel a strange hum and find themselves weak and quite sick. They make their way in the darkness towards each other and eventually find a light source, a glow stick.
They find that they have an in depth tattoo of numbers on their arm. they eventually find their lockers based on the number and are able to equip themselves with what they assume to be their personal items. once cleaned up and dressed they find themselves in front of a air lock door. they get the door open and witness this huge grotesque creature eating a human. it then glows a strange glow and walks into the wall, disappearing. once the coast is clear, they head down the hall and find another door. this one leads them into a huge chamber with thousands of deep sleep units. the heroes realize though that these are just common citizens, not military personal like themselves. they find some more equipment. when they go to leave the chamber, they are attacked by a sniper with a laser rifle from far down the hall in the direction that they intended to travel.
