The Thing: Alien miniatures expansion contains a set of four highly detailed character miniatures, to use in place of the Alien standees you can find into the base game box.

These miniatures represent the four 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 the standees enriches the game, giving it a more scenic aspect and a stronger impact to the gameplay.
