Nord and Bert, fully titled Nord and Bert couldn't make head or tail of it, is a comedic text adventure game from Infocom that uses figures of speech, homonyms, spoonerisms, and turns of phrase to weave a decidedly different adventure game.
The little town of Punster has been turned upside down by a malicious someone's tricks, words which previously worked to describe things now have been replaced by older turns of phrase, and it is up to you to unravel things and put everything back the way it was before.
The game has seven sections that must be played through to gain a phrase at the end. These phrases must be used to access the eighth and penultimate section. The first seven can be played in any order.
