Here are the key points of the expansion:
- A new board, new characters, and new materials.
- A new end game condition represented by the escape of the dog that will arrive at Outpost 31. IF this happens, you can play your next game of the 1982 version with a pack leader dog (a dog that behaves differently throughout the game).
- A new element in the game: teeth! The Thule Station crew discovers that the Alien cannot assimilate and duplicate metal parts, so dental fillings become a way to find out if a person is definitely human, but not if they are alien. The test with the wire and the flamethrower disappears and flashlights are added with which it will be possible to carry out a test and look at the teeth of the other characters, checking for the presence or lack of fillings.
- A new location is available for the Thing: The UFO! It represents the last hope of escape for the Thing, as in the movie. The final confrontation with any remaining humans will take place here. Of course, this is only an option, and just like the dog escape mentioned above, it doesn't necessarily happen! Everything will depend on your behavior, as you can win or lose in many ways!
