Much like the previous Super Star Wars Official Game Secrets, only for the second game in the trilogy. Prima didn't get the rights to do the guide for Super Return of the Jedi, so the series for them ended here. Tons of black-and-white sprite artwork, along with preliminary sketches, movie poster reproductions from around the world, and a slew of stills pulled straight from the movie and promotional materials.
While it does contain full stage maps and walkthroughs for every area, it does not include any of the cheat codes. So if you're looking for those, keep looking, sucker! Otherwise, this is about as comprehensive as you could have hoped for back in the day. And, naturally, any Original Trilogy fans should have this in their collection just for the extra nerd cred.
