Giten Megami Tensei: Tokyo Mokushiroku (lit. False Reincarnation of the Goddess: Tokyo Revelation) is a game that was first released for personal computers in 1997. It was published by ASCII and has plot ties to both Shin Megami Tensei and the manga Shin Megami Tensei: Tokyo Revelation, which it shares a subtitle. The game was rated 18 for sexual content. Like most other Megami Tensei games, there are multiple endings.
Tokyo was destroyed by ICBMs, resulting in nuclear holocaust. Several people were evacuated to an underground shelter, guarded by Devil Buster Special Forces, created by Hatsudai Katsuragi. The protagonist is Ayato Katsuragi, born and raised in the Hatsudai Shelter who wishes to follow in his father's footsteps and join the Devil Buster Special Forces.
- Giten Megami Tensei uses the "Demon EXP" system, which allows demons to gain EXP and level up.
- The Awakening Event is first seen in this game. The protagonist can obtain skills from 1~3 of four categories (Physical, Gun, Magic, and Computer) when leveling up, depending on his awakening type.
- The battle system is menu-based, but rather than a set turn order, after each turn a character has to cool down for a short period of time until they can act again. It's comparable to the Final Fantasy series's ATB system.
The PC-98 and Windows versions have several significant differences.
- The Windows version has a customizable interface, allowing the player to move and resize elements of the HUD.
- The Windows version has completely redone graphics as far as dungeon and HUD designs go. Enemy and character sprites were mostly untouched aside from an upscale job (possibly just recycling original assets from the PC-98 version).
- The music was redone for the Windows version.

Giten Megami Tensei: Distant Flow ~EXILE~ is a novelized version of the introduction to Giten Megami Tensei written by Takerube Nobuaki and Narita Miyako, with original art by Miyajima Katsumi, which was published in a December issue of TRPG's Logout in 1995. The character names and development differ somewhat from those used in the game.
- It is possible to see the ruins of the school that the main characters of Tokyo Revelation go to.
- In the Windows PC remake, time in between turns was measured based on the CPU's clock speed, leading to the game essentially being unplayable on later computers without a patch.
