9/25/2016: This module is closely connected with the “Metamorphosis Alpha” science fiction role-playing game that preceded “Gamma World” in TSR’s line of products. It served as a kind of gateway to Metamorphosis Alpha for D&D players, although that game (and Gamma World) never really took off the way the Fantasy Role-Playing Game did. It was originally designed by Gygax as a tournament scenario for playing at gaming cons, and it debuted at Origins II, the major competitor for Gygax’s own Gen Con. As such, it is written with an intended end-point, which forces the characters to get as much as possible and leave before time runs out. It includes maps of each level of the “dungeon,” as well as descriptions of new monsters and items. One interesting and unusual feature is a complete illustration booklet, with pictures of everything the PCs may encounter, that the DM can show them rather than trying to describe every odd-looking beast and object.
The basic premise is that a spaceship from another Universe has crash landed in a remote spot of the gaming world, and it is the “dungeon” that the players must explore. All of the original crew are dead, but various alien beasts were carried on board in a kind of space zoo, and they are now loose. There are also many surviving robots. Finally, various of the usual dungeon-dwelling species have wandered aboard the ship, some of them finding advanced weapons and technology, others being mutated by stray radiation. In all, it is a setting with many possibilities and it was a very popular module in its day. I remember running it myself at least once.
It does have some problems, not the least of which is inherent to most published modules: if your players have read it, they will know too much about it for it to really be fun. There are a lot of powerful weapons (like laser rifles, etc) to be found, and if the players immediately recognize what they are, they will rapidly become too powerful. The artists have done a good job designing technology that a first-time viewer may have a hard time guessing, but if they have advance knowledge, they’ll quickly kit themselves out with power armor and incendiary grenades and become unstoppable. The module suggests a rather complex system of flowcharts (reproduced in 1st edition Gamma World) for medieval characters trying to “guess” at the workings of new technology, but these are frankly boring and tedious, and most players will just say “I push the button. What happens?” rather than plod through them.
The other major criticism I have of the adventure is the lack of set-up for the DM. There are only a few paragraphs describing what the ship is and how it came to be here, and they are preceded by a lot of detail about how the doors, drop tubes, and lighting works with no context given. I didn’t re-read the whole thing before preparing this review, and it’s possible that somewhere in the ship there’s a recording tape or computer that has the whole log of the voyage and crash and gives complete information about the aliens and their culture, but it would be nice if this information was at the forefront, to allow DMs to improvise effectively when unexpected situations arise. The impression I get is that the aliens were humanoid, and possibly essentially humans with advanced technology, but it’s very hard to say from what the module says at the outset.
Nevertheless, this was a great exercise in imagination of the sort that made D&D such a big hit in the first place, and the adventure remains a classic of its kind, despite any flaws.
12/10/24: Not much to add, having re-read it a few times since this was written, except that, yes, the aliens were humans (hence all the human skeletons all over the ship) and no, we never really get their backstory, except that a “plague” struck the ship and apparently caused madness and the death of all of the crew and passengers.. I think what is more relevant is that the ship is frankly too big and too empty, and that DMs will want to “rush” players a bit to get to the cooler areas and more interesting encounters and treasure.
