Following Kenner's ill-fated first foray into the board game market with "Alien Game", merchandising efforts in the medium were stagnant, until Leading Edge Games released the cooperative game "Aliens" in 1989. Leading Edge Games released "Aliens Adventure Game" in 1991, to mixed reviews and commentary that states it functions closer to a board game than a traditional tabletop RPG. In 1993, British toy company Peter Pan Playthings Ltd released a board game called "Operation: Aliens — Combat Game", in which up to four players play as Colonial Marines and compete to reach the center of the board and self-destruct the Alien-infested facility. In December 2019, Swedish publisher Free League Publishing released a tabletop role-playing game called "Alien: The Role-Playing Game", featuring two game modes. An upcoming licensed board game titled "Alien: USCSS Nostromo" is set for release in 2020. However, in 2018, a French board game designer named François Bachelart accused the game's publisher, Wonder Dice, of theft of a game concept he pitched to them years prior. Wonder Dice published a press release, in which they threatened to sue anyone who would question their legal practices.
