Trinity

Trinity explores the history of nuclear weaponry by sending the player through time to pivotal moments leading up to the atomic bomb. It begins in a present-day nuclear strike and sends you to locations tied to the Manhattan Project, such as the Trinity test site in 1945.

Trinity was both developed and published by Infocom in 1986. It was designed by Brian Moriarty, who is also known for his work on the classic game Loom.

As a classic Infocom text adventure, players must use a verb-noun parser to solve inventory-based puzzles and navigate the time-travel narrative. You frequently need to manipulate specific historical items and creatures, like a talking roadrunner, to progress through the timeline.

Like many 1980s Infocom games, the original release shipped with physical extras known as "feelies" inside the box. These items included a map of the Trinity site and a cardboard sunshade to prevent glare on the player's floppy disk.
