Explosive Fighter Patton from 1988 is believed to be the first video game to use the swear word "fuck", referring to the Famicom Disk System as the "fucking box". It is not known if this is an in-joke or a translation error.

This is followed by Skweek for Amstrad CPC in 1989, whose development builds leaked to the UK market, featuring a variety of vulgar in-joke placeholder phrases. The swearing version of the game has not known to be preserved, but it is alleged that one of these quotes was "fuck your mother!". This would make it the first use of "fuck" to be known for a fact to have been intentional, even if its distribution wasn't.

1990's Paranoia, the Japanese version of Psychosis features an 8-bit sound effect upon stage clear that appears to be made to evoke the phrase "fuck you!", which is played in accompaniment with an alien flipping the bird. This is technically the first vocalized use of "fuck", but is not a recording of a human voice, and is the first for-a-fact intentionally included use of "fuck".

1991's Llamatron contained a voice sample of the word "oh, fuck!" which was cut off. A glitch made it so that if you paused the game upon dying, it would play uncensored, making it the first clear vocalised use of "fuck", even if still not intentionally added.

1995's The Orion Conspiracy contains one of the earliest known uses of "fuck" that was clearly spoken, uncensored, and known for a fact to not be an oversight. Also of note is Discworld, released in the same year, having an Easter egg referencing John Cleese's 1989 eulogy to the late Monty Python member Graham Chapman. While both games released in the same year, it is unknown which game came out first as Discworld is the only one of the two to have a known release date, coming out on March 17, 1995.
