Multiverse Alpha Release file

Operation Multiverse is a project I have been wanting to do for a long time. The goal of this mod is to combine all of the characters, items, and weapons from some of the original first person shooters. In the end there will be a new episode that ties all the stories of Duke, Wolfenstein, Doom, Blood, and Shadow Warrior together. Until then though, the Duke Nukem episode has been setup for random mode.
