An all-time great. — “This really is one of the best sets Lego has ever released. The walking mechanism is great, the head and back-end can be removed and combined together, the body is a silo for two rockets and the whole thing looks fantastic. There are plenty of little details such as... More containers in the front legs for rock/mineral samples, and the 'tail' is a fully-moving mechanical arm. First-class.”

Lego Maniacs' Guide
“I hate to accuse the Lego Group of trying to copy designs from somebody else but you have to admit the designers probably spent at least one or two afternoons watching The Empire Strikes Back when they went to their drawing boards and came up with the Alien Moon Stalker.... More Still, this model stands out among the Lego lineup of innovative modes of space exploration.”

“Rocket-launching elephant-like walker with detachable fore and aft vehicles piloted by red and blue astronauts. Pretty rad. Alien Moon Stalker is like the Mega EX evolved form of 1980’s Mobile Lab (6901).”
