You escaped from the vat in a science lab and discovered they were experimenting on Aliens. You then made your way upwards only to find another lab where they were experimenting with Vampires. They are obviously doing some very strange research here and you need to find out what they have done to you! Bits and pieces of memory are coming back to you but they are very fragmented, you are beginning to feel good again and it's only a matter of time before you are back at full health and have full recall. In the meantime you must continue to make your escape and discover more about what you are.
