So Infocom (oops, Activision!) has returned to its roots with Zork: The Undiscovered Underground. But the game is more parody of Zork games than a Zork game itself, but therein lies some of its appeal.
For one, you start out with a plastic sword of no antiquity, and a battery powered plastic lantern which totally sucks. Finding a way to get it to stay alight long enough to complete the game is a puzzle in itself.
Basically, you're exploring a new cave on assignment from the Grand Inquisitor himself, because all the other (better) adventurers are busy for one reason or another.
Despite some obvious continuity errors (Spoiler - click to show) Such as a grue with glowing fur! The game is a fun mini-zork, complete with 2 different endings. Expect appearances from the implementors and the grues (which appear much smarter in this one than in any previous installment).
The puzzles aren't extremely difficult, and many of them are at least logical, which is a nice change of pace from the ECHO room of Zork I. (Yes, there was a more practical solution- added well AFTER the fact as the "real" solution did not appear in Dungeon).
Overall, it seemed like the game was made as a commercial for Zork: Grand Inquisitor, but it is nice to see another offical Zork after all these years, even if the years have not been friendly to the GUE.
