Robotech II: The Sentinels is a stand-alone role-playing game that uses the rules from the Palladium Role-Playing Game. The game uses a campaign setting that takes place in the Robotech universe but the adventures take the players to new places.^[1] As a guide for players, the book presents information on character statistics, new technology, random encounters, two short scenarios, and combat data for soldiers.^[2]

The complex combat rules have been characterized as "excruciatingly detailed."^[1]

Robotech II: The Sentinels was written by Kevin Siembieda and was published by Palladium Books in 1987 as a 144-page book with cover art by Kevin Long, and interior art by Long, Thomas J. Gould, Kevin Siembieda, and Tatsunoko Production.^[2]

In the June 1989 edition of Games International (Issue 6), Jake Thornton was not pleased with the production values of the book, noting that it was a "flimsy softback with a curled-up cover." He also noted that to properly understand the RPG and its rules, the player would need the first volume in this series of books. What rules there were in this volume he found ambiguous and lacking in cohesion. Thornton concluded by giving this book a very poor rating of only 1 out of 5.^[3]

In his 1990 book The Complete Guide to Role-Playing Games, game critic Rick Swan compared this game to its predecessor, Robotech, and found "With its expanded skill lists, extensive background material, and brief but adequate introductory scenarios, Sentinels emphasizes role-playing more than Robotech and is therefore a more interesting game." Swan concluded by giving this game a solid rating of 3 out of 4, saying, "It's not for newcomers — players who have never heard of Macross, Mecha, or other elements of the Robotech universe won't have a clue what this is all about — but fans of the Japanese cartoons will find plenty to enjoy."^[1]
