Blacksad: Under the Skin was developed by the Spanish company
Pendulo Studios, the country's longest-running game developer by 2019. YS Interactive initially assisted the team on
Blacksad. According to Pendulo, the idea of adapting the
Blacksad comic series into a game was first proposed by Pendulo's publisher
Microïds, directly after the two companies had completed
Yesterday Origins in November 2016. Microïds was owned by the same
media conglomerate as
Blacksad publisher
Dargaud. the developer's Josué Monchán noted that the team had "been Blacksad fans for a long time" and agreed to the idea immediately. The project was unexpectedly announced in June 2017 and was initially scheduled for a late 2018 release. Giada Zavarise of
Rock, Paper, Shotgun wrote of the announcement, "In the world of games, the news was received with a shrug. But in the comics scene, people were screaming incoherently."
Gameblog's Vincent Elmer-Haerrig called the plan a "gamble" for Pendulo, as
Under the Skin is aimed at "a fringe of players who are both comic-philes and video game lovers." Pendulo collaborated with
Blacksad creators
Juan Díaz Canales and
Juanjo Guarnido on
Under the Skin. The developer described the pair as
consultants,
Blacksads authors also offered input on the game's voice direction. Canales requested a deep voice for John Blacksad because of the character's heavy smoking; the team hired Barry Johnson of
Detroit: Become Human for the English version, and Gabriel Jiménez—voice of
Hugh Jackman in Spanish film dubs—for the Spanish version. Guarnido said that "the narrative is strong and we took care that it does not interfere with the stories of the comic series".
Under the Skins first
teaser trailer was revealed in August 2018, around the time of its showing at
Gamescom. The game proceeded to appear at the 3D Wire festival in Spain that October. By February 2019, it had been in production for over two years.
Mundo Deportivo reported at the time that
Blacksad was "in the final phase of development". Microïds attributed the delay to a desire for increased polish in the final product. Although the game received a subsequent delay to 14 November, its European
Xbox Marketplace and
PlayStation Store versions nevertheless appeared due to a technical error on 5 November. Microïds advised buyers not to play the game before the release of its planned "day-one
patch", set to coincide with
Under the Skins wider release on 14 November. According to Microïds, the patch will add more sound effects to the game, fix "major bugs" and heavily increase the
frame rate, among other improvements. Discussing the situation at the time,
Destructoids Chris Moyse wrote, "You have to feel for the developers in what must be a very stressful and unfortunate situation." While the game met its planned 14 November release date, Jorge Cano of
Vandal characterized
Under the Skins overall rollout as "simply disastrous" and as "an example of how to do things wrong when it comes to putting a game on sale". Patches soon followed to fix some of the game's bugs and instabilities at launch. ==Reception==
