1998–2000: Conception and first game In 1998, following the dissolution of Danish game developer
Zyrinx, its remaining team members regrouped to form
Reto-Moto. This team later established
IO Interactive (IO), which would go on to create its first intellectual property, the
Hitman series. The inaugural game,
Hitman: Codename 47, marked IO's debut in the gaming industry. Initially, the studio had planned to develop a straightforward shooter titled
Rex-Domonius, but the concept was ultimately abandoned by Reto-Moto. Published by
Eidos Interactive in 2000,
Codename 47 was initially released exclusively for Windows. Andersen noted that the decision to focus on PC development was driven by the difficulty of obtaining console development kits at the time, as well as the growing availability of 3D hardware for PCs, which made the platform particularly appealing for innovation.
Hitman: Blood Money, developed by IO and published by Eidos Interactive, was released for Microsoft Windows, PlayStation 2, Xbox, and
Xbox 360 in May 2006. Developed concurrently with its predecessor,
Blood Money continued the story from the previous installment and represented a significant leap forward in terms of graphics, AI, and level design, thanks to increased resources from both IO and Eidos.
Blood Money has been re-released multiple times: first as part of an HD collection alongside its two predecessors in 2013, again in 2019 as part of another HD collection with its successor, and most recently for mobile devices in 2023 and the
Nintendo Switch in 2024. A box set titled
Hitman Trilogy (released as
Hitman: The Triple Hit Pack in Europe) was published by Eidos for the PlayStation 2 on June 19, 2007, in North America and June 22, 2007, in Europe. The collection includes
Silent Assassin,
Contracts, and
Blood Money, with the games remaining identical to their original standalone releases. Following the release of
Blood Money, IO Interactive shifted its focus to developing new franchises, including the action-packed
Kane & Lynch series (2007 and 2010) and the more family-friendly
Mini Ninjas (2009).
2011–2015: Absolution and second hiatus Hitman: Absolution was developed by IO Interactive and published by
Square Enix, following their acquisition of Eidos Interactive in 2009. It was released worldwide on 20 November 2012 for
Microsoft Windows,
OS X,
PlayStation 3, and
Xbox 360. The developers stated that
Absolution, while retaining stealth elements, would move away from the sandbox levels of the first four games and incorporate more action-oriented features, such as a cinematic story-driven narrative and increased emphasis on gunplay, to appeal to a broader audience. Despite selling over 4.5–5 million copies, the game failed to meet Square Enix's sales expectations. On 15 May 2014,
Hitman: Absolution — Elite Edition was released for OS X by
Feral Interactive, featuring all previously released
downloadable content, including
Hitman: Sniper Challenge, a "making of" documentary, and a 72-page artbook. In January 2013, Square Enix released HD remastered versions of
Silent Assassin,
Contracts, and
Blood Money for PlayStation 3 and Xbox 360 under the title
Hitman HD Trilogy. The collection was released in North America on 29 January 2013, in Australia on 31 January 2013, and in Europe on 1 February 2013.
Hitman Go, a turn-based
puzzle video game developed by
Square Enix Montreal, was released for
iOS on 17 April 2014 and for
Android on 4 June 2014. A version for
Microsoft Windows and
Windows Phone was released on 27 April 2015. A "Definitive Edition" featuring improved visuals and additional content was released for
PlayStation Vita,
PlayStation 4, and PC via
Steam on 23 February 2016.
Hitman: Sniper, a
first-person shooter developed by Square Enix Montreal, was released for iOS and Android on 4 June 2015. Unlike traditional
Hitman games, it focuses solely on sniping mechanics, with players taking on the role of Agent 47 to eliminate targets from a fixed position using a
sniper rifle. The game lacks a narrative component and emphasizes precision and strategy.
2015–present: World of Assassination trilogy, self-publication, and Freelancer Following the underperformance of
Absolution, IO Interactive reimagined the franchise, blending the gameplay elements introduced in
Absolution with the open-ended design of earlier
Hitman games. A soft reboot, simply titled
Hitman, was announced at
E3 2015 and published by
Square Enix. The game's first level launched in March 2016 for
Microsoft Windows,
PlayStation 4, and
Xbox One, receiving highly positive reviews. Structured episodically,
Hitman featured six levels released monthly throughout 2016, alongside additional content such as "Elusive Targets", "Escalations", and user-created "Contracts". This episodic approach allowed IO to refine each level while creating a live game that expanded over time, laying the foundation for the series' future. Despite critical acclaim, the game did not meet Square Enix's financial expectations. In 2017, Square Enix parted ways with IO Interactive, allowing the studio to retain full control of the
Hitman IP and become independent. IO abandoned the episodic format for its next title,
Hitman 2, which was announced in June 2018 and published by
Warner Bros. Games. Released in November 2018 for Microsoft Windows, PlayStation 4, and Xbox One, the game featured six large sandbox levels, a multiplayer mode, and post-launch content. Players could also import levels from the 2016 game, retaining their progress if they already owned it. In January 2019, Warner Bros. Games released the
Hitman HD: Enhanced Collection for PlayStation 4 and Xbox One, featuring updated ports of
Blood Money and
Absolution with improved graphics,
4K resolution, and modernized controls.
Hitman 3 was revealed at the
PlayStation 5 reveal event in 2020 and released in January 2021 for Microsoft Windows, PlayStation 4, PlayStation 5, Xbox One,
Xbox Series X/S,
Stadia, and
Nintendo Switch (as a
cloud version). Developed and self-published by IO Interactive, the game allowed players to carry over progress from the previous two titles and introduced
VR support, extending to imported levels from earlier games. In January 2023, IO merged
Hitman and
Hitman 2 into
Hitman 3, renaming it
Hitman: World of Assassination. A digital-only collection of the
World of Assassination trilogy, released on 20 January 2022, included
Hitman 3 and access passes for content from
Hitman and
Hitman 2. A
Premium Add-Ons bundle offered all DLC except for
Hitman 3s "Seven Deadly Sins" expansion. The collection was available for PlayStation 4, PlayStation 5, Xbox Series X/S,
Steam, and
Epic Games. Under license from IO,
Hitman Sniper: The Shadows, a sequel to
Hitman: Sniper, was developed by
Square Enix Montreal and released for
iOS and
Android on 3 March 2022. The game retained the sniping mechanics of its predecessor but did not feature Agent 47 as a playable character. This marked the final
Hitman game published by Square Enix before it sold most of its assets to
Embracer Group, and the game was discontinued by January 2023. On 26 January 2023, IO Interactive launched the "Freelancer" mode for
Hitman 3. This mode follows Agent 47's life in a safehouse as he dismantles crime syndicates with Diana as his handler. Players choose targets and gear, balancing risk and reward, as failure results in losing equipment. The mode includes 100 mastery levels, unlocking new gear, outfits, and safehouse decorations. On 27 August 2025,
Hitman World of Assassination was released for iPhone and iPad by IO Interactive. The release brought the entire trilogy to iOS devices. The iOS version features touch controls and support for external game controllers while not compromising gameplay.
Future IO Interactive has confirmed that while
Hitman 3 concludes the
World of Assassination trilogy, it will not be the final game in the franchise. During December 2025, in an interview conducted by
Variety, IOI CEO Hakan Abrak confirmed that once IOI have shared additional information about the new co-op mode, that is being introduced to the
World of Assassination trilogy, they will then begin sharing new information around the next Hitman game. == Reception ==
