A coop deck builder for 1-5 players pitting you against an unending hoard of alien warriors,and face huggers. A brick of a box for the price. All components are high quality. Box has built in dividers for 2 rows of cards and the game mat. Game provides a very suspenseful ride thru the world of Alien. Choose your characters from the majority of the cast of the core 4 films, you can mix and match characters and scenarios from the 4 films to keep things fresh every game. One thing I really like about the mechanics are that the game gets progressively harder the more players at the table making teamwork absolutely essential to victory.
