The Thing: Alien miniatures expansion contains a set of four highly detailed Alien miniatures, to use in place of the Alien standees you can find into the base game box.
These miniatures represent the 4 stages of evolution of The Thing, with some iconic shapes seen in the movie, such as the Spider-Head or the Norris-Thing.
Using these Alien miniatures in place of Alien standees enriches the game giving it a more scenic aspect and a stronger impact to the gameplay.
