Tyranid Attack - Part 1

About Tyranid Attack, from BoardGameGeek:

Attack the Genestealers and their more frightening cousins, the Tyranids, in their huge living ships. Your job is to take a squad of Space Marines into the bowels of the ship and try to destroy its vital organs. The ship is not defenseless as you could find a Genestealer or Tyranid opposing you. This time, unlike in the game Space Hulk, lighter armored but faster Space Marines are going in, in addition to heavily armoured Terminators, and the opponents now have weapons.
