Legendary Encounters is a deck building game based on the four Alien movies that use

the Upper Deck Marvel Legendary card game mechanics.  The players pick an avatar out of a list of Alien movies archetypes (scientists, gunner, synthetic, corporate executive, scout, priest, mercenary, etc.) and use recruit points to gain new cards and strike points to defeat xenomorphs.  It can support solo play and is tense at time and exciting.
