It's done very professionally and [it] doesn't have to hide from Star Wars, Star Trek and [the like]."[2]Jeuxvideo.com wrote, "Adapting a work from its original medium to a new medium is often a perilous undertaking, as experience has repeatedly demonstrated. However, Perry Rhodan comes out of it with honors, switching from paper to silicone with brilliance. True to the spirit of the saga, the game nevertheless manages to be accessible to neophytes while writing a new page that is frankly successful."[9]Eurogamer wrote, "It's one of the richest, most cohesive entries in the point-and-click genre I've seen for a long time, and I'm a little sad that it didn't come out fifteen years ago. Just think of all the sequels we could've had by now."[4]Adventure Gamers wrote, "It's an auspicious debut that should appeal to sci-fi adventure fans, even if you're not familiar with the American astronaut and his 'Perryverse'."[3]

Others looking for a well-thought out and engaging adventure may want to look elsewhere."[7]IGN wrote: "This adventure is only recommended for hardcore fans of the genre who don't mind zany logistical puzzles; otherwise, you should beam yourself the hell out of there."[8]GameSpot wrote: "Even an innovative sci-fi setting can't save the illogical and boring Immortals of Terra."[6]
