GURPS Supers was written by Loyd Blankenship, with a cover by Alan Gutierrez and Charlie Weidman, and was first published by Steve Jackson Games in 1988 as a 112-page book.

[3]: 107 The 2nd edition of GURPS Supers was published in 1990 and featured a cover by John Zeleznik.

[5] In the August 1989 edition of Games International (Issue #8), James Wallis liked the design and layout of the book, but pointed out that "the rewriting of a large number of rules [...] shows that GURPS is not a truly generic rolegame and makes GURPS Supers substantially harder to learn".

Wallis concluded by giving this book a below average rating of only 2 out of 5: "For my money, GURPS Supers is flawed [...] There is too much emphasis on rules changes; it fails as a superhero rolegame because of the overrealism of the GURPS rules, and it fails as a generic sourcebook because it is not generic".

[6] In the September 1996 edition of Dragon (Issue #233), Rick Swan compared the second edition of GURPS Supers to Champions, and commented that "GURPS Super takes a more realistic route, stressing personality over punch-outs.

[7] In the May 1996 edition of Arcane (issue #6), Steve Faragher gave the second edition of GURPS Supers a below-average rating of only 6 out of 10, and called the background setting "rather dull", saying it is "fine if you want to recreate a Saturday afternoon TV show, but not so great for a more fantastic, underground campaign of the Watchmen variety".

Faragher concluded that "it's a competent enough set of rules - and one that's well presented - but GURPS Supers is not exactly compulsive playing material".
