The Lost Treasures of Infocom is a 1991 compilation of 20 previously-released interactive fiction games developed by Infocom. It was published by Activision for MS-DOS, Macintosh, Amiga, and Apple IIGS versions. It was later re-released on CD-ROM, and in 2012 on iOS. Gameplay The Lost Treasures of Infocom compiles 20 interactive fiction titles, with which the player interacts via text parser. The compilation includes Zork I, II and III, along with the Zork-connected games Beyond Zork, Zork Zero, Enchanter, Sorcerer and Spellbreaker. The other titles included are Deadline, The Witness, Suspect, The Lurking Horror, Ballyhoo, Infidel, Moonmist, Starcross, Suspended, Planetfall, Stationfall and The Hitchhiker's Guide to the Galaxy. The package contains all the instructions (bound in one volume) and maps for each game as well as all the InvisiClues, printed normally instead of using "invisible" ink. The package also features a launch menu which lets the user select which one of the 20 games they wish to play. Some significant omissions from the package were the "feelies" for which Infocom had become known. The package merely contained photocopies or pictures of these items, such as the sunglasses from Hitchhiker's Guide and the Stellar Patrol ID card from Planetfall.

After the company's restructuring during bankruptcy, it began to lean on its back catalog of licenses, including Zork. Activision CEO Bobby Kotick later said that "Zork on a brick would sell 100,000 copies". Infocom had been closed by Activision in 1989; the publisher held the copyright to nearly all the past Infocom titles. An additional bonus was the updated version of Hitchhiker's Guide. The game was repackaged using a later version of the Z-machine than the original, and now featured a built-in hint system. Reception The Lost Treasures of Infocom was a commercial hit. Peter Doctorow of Activision reported in 1992 that The Lost Treasures of Infocom was "selling extremely well". Jeremy Reimer of Ars Technica wrote, "Retailing for $99, it sold over 100,000 copies and was almost pure profit. The ashes of Infocom saved Activision from bankruptcy." Brian Walker of Computer Games Strategy Plus declared The Lost Treasures of Infocom Activision's best game of 1992. Reviewing the iOS version of the game in 2017, TouchArcade gave it a
