In 2013, he wrote the story and in-game text for the Joe Dever's Lone Wolf video game series specifically designed for tablets and smartphones.

Entitled Lone Wolf: Blood on the Snow, it was developed by Forge Reply (Milan, Italy) and published by BulkyPix.

On 11 January 2016, the developer Forge Reply announced that Joe Dever's Lone Wolf had achieved 2.5 million downloads since its release in November 2013.

[6] Dever was a bass guitar player and attempted to get a record deal when playing with Essex-based band Seventh Seal.

It proceeded without complications on 10 August 2005,[9] and subsequently Dever made a swift recovery, having retained sufficient kidney function to lead a normal life without any need for dialysis.

[12] Joe Dever was seven years old when he became a fan of the comic strip "The Rise and Fall of the Trigan Empire" which appeared in a magazine called Look and Learn.

He also built up armies of Airfix Roman soldiers and converted their spears to laser rifles long before he was introduced to fantasy.

[14] The story is based around Lone Wolf, who is a young cadet in a monastic order of warriors known as the Kai Lords who defend their home of Sommerlund from the forces of evil, embodied by the Darklords of Helgedad.

The rest of the book series follows Lone Wolf and, later, his successor in their attempts to take revenge on the Darklords and then to thwart the plans of Dark God Naar to control their world for evil.

Subsequently, the Lone Wolf series has been published in over 30 countries, translated into 18 languages, and has sold in excess of 12 million copies to date.

[19] In 1999, Dever gave his permission for the Lone Wolf books, numbers one through twenty, to be published for free on the internet by the non-profit organization Project Aon.

[20] In July 2014, on the 30th anniversary of the first publication of Flight from the Dark, the 28th book in his Lone Wolf series was released online by Project Aon.

The first of the new Lone Wolf Collector's Editions, Flight from the Dark, was thoroughly revised and expanded by Dever with the addition of two hundred new sections.

In April 2010, the German language translation (Einsamer Wolf: Flucht aus dem Dunkel) won the Best Fantasy Gamebook Award at the RPC Event in Cologne, Germany.

On 1 December 2015, Cubicle 7 Entertainment Ltd acquired the license to publish the Lone Wolf Gamebooks from Mantikore-Verlag, pushing the publication of book 29 in English to spring 2016.

[26] Since 2022, Holmgard Press has started republishing the whole series as a "Definitive Edition" which aims the mass market, with newly revised version of the books.

On 14 January 2016, French Publisher Gallimard Jeunesse announced that their Loup Solitaire editions have sold in excess of 2.8 million copies since first publication in 1986.

In addition to Lone Wolf, Dever has also created two other role-playing gamebook series (Freeway Warrior and Combat Heroes) and designed several best-selling computer and video games for PCs and consoles.

The Combat Heroes gamebooks are illustrated adventures where each paragraph is a full-page picture representing what the player sees, with two modes.

Following a successful Kickstarter campaign August–September 2014, the new RPG was launched at Gen Con 2015 (Indianapolis USA) in late July / early August 2015.

On 7 March 2016, Dever's Lone Wolf Adventure Game was nominated for 'Game of the Year' and 'Best Art & Presentation' in the prestigious Golden Geek Awards.
