3DM

3DM was a Chinese video game piracy group active from 2006 to 2016. Founded by Su Feifei (known online as Bird Sister) as an unofficial localization team on the 3DMGame forum, the group specialized in cracking digital rights management (DRM) protections for commercial PC games and distributing Chinese-localized versions.^[1]^[2] The group gained prominence for early successes against advanced DRM systems, including the first crack of Denuvo-protected titles in 2014, but announced a one-year hiatus for single-player games starting February 2016 to assess sales impacts, after which it effectively ceased operations due to cracking difficulties.^[3]^[2]

Background

Founding

The 3dmgame.com platform originated in 1999, initially as a forum focused on game localization and introducing overseas titles to Chinese players. In 2000, it was established as "3D美少女论坛," and by 2004, it was renamed 3DMGAME, expanding into single-player games and building a core community through localization and technical sharing.^[4] The associated company, Beijing Sandingmeng Software Service Co., Ltd., was formally established around 2001 by Su Feifei and co-founder Liu Yan, operating as a software service provider based in Beijing, China.^[5]^[6] The website served as an online forum dedicated to PC gaming resources, initially providing a platform for users to discuss and share game-related content amid growing interest in console and PC titles in China.^[5] This forum quickly fostered a vibrant community, with early growth driven by user contributions and interactions around gaming news, strategies, and modifications, capitalizing on the limited availability of localized content in the domestic market.^[5]^[1] Responding to demand for accessible games, operations transitioned toward localization and distribution services, exemplified by the formation of the 3DM localization team in 2006 as a volunteer group of forum enthusiasts producing non-profit translations.^[1] Under Su Feifei's leadership, the organization expanded into broader game-related activities, including community-driven sharing of cracked programs.^[6]

Leadership and organization

3DM's leadership was centered around its pseudonymous founder and primary decision-maker, "Bird Sister" (also known as Phoenix), the online alias of Su Feifei, who served as the public face of the group and communicated key announcements through her personal blog until the group's piracy activities ceased around 2016.^[7] Unusual for piracy collectives, Bird Sister maintained visible online profiles, including on Sina Weibo, to share updates and engage with the community.^[8] The organization functioned as a hybrid structure combining formal company operations with volunteer contributions, headquartered in the Fengtai District of Beijing, where its operator managed forum activities and faced legal actions in local intellectual property courts.^[9] Core roles were divided among cracking teams responsible for bypassing DRM protections, localization groups that translated and adapted games for Chinese audiences, and distributors who facilitated sharing via the 3DM forum.^[1] The localization efforts originated as a non-profit volunteer initiative formed by forum users in 2006, highlighting the collective's reliance on community involvement alongside paid staff for operational tasks.^[1] Public profiles on platforms like the 3DM forum and social media served dual purposes for recruitment—drawing in skilled volunteers and crackers—and for disseminating organizational updates, fostering a sense of community within the piracy ecosystem.^[7] This model allowed 3DM to scale its activities efficiently, blending professional oversight with grassroots participation to handle the demands of game cracking and distribution until its suspension of such operations in 2016.^[10]

Operations

DRM cracking

3DM specialized in reverse engineering digital rights management (DRM) systems employed by platforms like Steam, Origin, and early iterations of Denuvo to enable unauthorized access to PC games. This expertise allowed the group to target protections designed to prevent copying and execution without valid licenses, focusing primarily on single-player titles where online authentication was minimal.^[2] From the early 2000s until their 2016 suspension of cracking activities, the process began with detailed analysis of the game's executable files, often using disassembly tools to deconstruct binary code and identify DRM enforcement routines. Reverse engineers would trace how the software verified licenses, such as through API calls to Steam or Origin servers, revealing vulnerabilities in authentication flows. This phase required emulating server responses or key validation logic to test modifications without triggering anti-debugging measures.^[11] Once the DRM mechanisms were understood, 3DM created emulation routines for key generation, simulating the legitimate licensing process to produce valid activation keys or bypass checks entirely. Patches were then developed to alter the executable, removing or neutralizing protection code while preserving the core gameplay functionality to avoid introducing bugs or performance issues. These modifications ensured the cracked version ran offline and independently of the original DRM infrastructure.^[8] Cracks for single-player games were typically released within days to weeks following a title's official launch, depending on the complexity of the DRM implementation. Early Denuvo versions proved particularly challenging but were eventually overcome through persistent iteration on these techniques, though later updates extended cracking timelines significantly. This rapid turnaround highlighted 3DM's proficiency in balancing thorough analysis with efficient patch deployment.^[12]

Localization and distribution

3DM played a significant role in localizing Western video games for the Chinese market, adapting interfaces, subtitles, and occasionally audio tracks to Chinese to make them accessible to non-English-speaking players. Founded in 2006 as an unofficial team of forum users, the 3DM Localization Team produced non-profit translations for numerous titles, enhancing their appeal in regions where official localizations were limited or absent.^[1] This process often built upon cracked versions of games, allowing the group to customize content for cultural and linguistic relevance without official publisher involvement.^[7] The group distributed these localized, cracked games primarily through peer-to-peer networks such as torrents, their own private online forum, and various direct download sites. Releases were typically bundled with the necessary cracks, installation instructions, and user manuals to facilitate easy access for end-users. A 2017 court ruling against 3DM explicitly ordered the cessation of such distributions, highlighting the scale and methods of their operations.^[13] Over its active years, 3DM released cracks and localizations for numerous PC games, positioning the group as one of the world's largest sources of pirated titles, particularly in Asia where demand for affordable access to international software was high. This prolific output underscored their influence in the regional piracy ecosystem, though it drew repeated legal challenges from game developers.^[14]^[15]

Key events

Early activities

3DM began its operations in 2001 as 3DHGAME, a niche forum primarily focused on introducing and discussing Japanese adult games, particularly 3D titles. By 2003, under founder Liu Yan's direction, it rebranded to 3DMGAME and pivoted toward comprehensive coverage of Western 3D games, including news, strategies, and user resources, marking the start of its broader prominence in China's gaming scene.^[16] During the mid-2000s, 3DM achieved rapid expansion by cracking and localizing popular titles from major publishers like Electronic Arts (EA) and Ubisoft, which drew a surging user base to its forums. Notable examples include early cracks for EA's Mass Effect series, such as the group's nationwide first release of a cracked Mass Effect 3 in March 2012, enabling offline play without original disc requirements. For Ubisoft games, 3DM provided cracks for the Assassin's Creed series starting from the original 2007 title, often integrating them with forum-hosted downloads to bypass DRM. This activity built a dedicated community, with the forum reaching over 4 million registered users.^[16]^[17]^[18] A loose organizational structure of volunteer enthusiasts and core moderators facilitated these efforts, allowing quick responses to new releases. 3DM engaged its audience through integrated blogs on the forum and Sina Weibo posts starting around 2009, where leaders like founder Su Feifei shared updates on cracks and localizations, promoting free access to global games amid high import costs and limited official availability in China. This built a loyal following.^[16] Initially offering simple DRM bypasses, 3DM evolved to deliver comprehensive packages by the late 2000s, combining cracks with full Chinese translations and patches to resolve regional restrictions like language locks and geo-blocks. The 3DM localization team, formed in 2006 from forum volunteers, produced nearly 300 such adaptations by 2013, focusing on high-quality, non-profit work that amassed billions of downloads and solidified the group's reputation.^[16]^[1]

Denuvo confrontations

In late 2014, 3DM achieved a significant milestone by cracking the Denuvo digital rights management (DRM) system in the major title Dragon Age: Inquisition, released on November 18, just 15 days after its launch.^[19] This breakthrough, announced on December 1, demonstrated 3DM's technical prowess against the then-new anti-tamper technology, which was designed to prevent unauthorized copying of PC games.^[20] The rapid success solidified 3DM's reputation as a leading cracking group capable of bypassing advanced protections, influencing subsequent efforts by other piracy collectives.^[3] By January 2016, however, 3DM's leader, known as Bird Sister, publicly expressed concerns over Denuvo's evolving defenses, particularly its version 4 updates, which had rendered cracking major releases like Just Cause 3 increasingly difficult and time-intensive.^[12] In an announcement on the group's forum, she predicted that ongoing improvements in Denuvo could lead to the "death" of game piracy within two years, as protections outpaced crackers' abilities.^[3] This statement highlighted the escalating challenges, with some titles remaining uncracked for over a month post-release, prompting 3DM to declare a one-year hiatus from cracking single-player games starting February 8, 2016, to assess piracy's impact on industry sales.^[2] Just days into the hiatus, on February 11, 2016, 3DM reversed course by claiming a successful crack of the latest Denuvo iteration, targeting protections in games such as FIFA 16, Just Cause 3, and Rise of the Tomb Raider; however, while this allowed releases for specific titles, subsequent Denuvo updates continued to challenge the group.^[21] The group stated it would resume releases for older or less-protected titles but anticipated delays of several months for newer Denuvo-secured games, reflecting the sustained difficulty of the DRM's advancements.^[22] This development underscored the ongoing cat-and-mouse dynamic between 3DM and Denuvo, where breakthroughs were tempered by the technology's iterative enhancements.^[23]

Legal issues and decline

Major lawsuits

In 2016, Koei Tecmo filed a lawsuit against 3DM in the Beijing Intellectual Property Court, alleging copyright infringement through the unauthorized cracking and distribution of five of their games, including Romance of the Three Kingdoms 13, Nobunaga's Ambition: Sphere of Influence, Dynasty Warriors 8: Empires, Samurai Warriors 4-II, and Nobunaga's Ambition: Sphere of Influence - Ascension.^[13]^[24] The suit followed repeated warnings from Koei Tecmo to 3DM to cease the illegal activities, which the group ignored.^[25] On September 29, 2017, the court ruled in favor of Koei Tecmo, finding 3DM guilty of illegally accessing and distributing the protected intellectual property.^[26] The judgment imposed a fine of 1.62 million yuan (approximately $245,000 as of 2017) in damages and legal fees, and issued a permanent injunction ordering 3DM to immediately stop all distribution of the pirated versions of Koei Tecmo's games.^[13]^[9] This case marked one of the earliest significant legal victories by a foreign game publisher against a major Chinese piracy organization, highlighting China's evolving enforcement of intellectual property rights in the digital space.^[25] Prior to the Koei Tecmo action, 3DM had encountered smaller-scale legal pressures from international publishers seeking to curb their operations, though these did not yield comparable court-mandated penalties or injunctions.^[24] The 2017 ruling underscored the vulnerabilities of piracy groups to targeted litigation, contributing to increased scrutiny on 3DM's activities in subsequent years.^[13]

Cessation of operations

Following the September 2017 ruling by the Beijing Intellectual Property Court in the lawsuit filed by Koei Tecmo, 3DM was ordered to immediately cease distributing cracked versions of the company's games and comply with injunctions against further infringement of Koei Tecmo's intellectual property.^[13] The group adhered to these court orders by removing Koei Tecmo titles from its site.^[9] This compliance, along with the ruling's upholding on appeal in May 2018, marked the beginning of a gradual decline in 3DM's cracking activities amid ongoing legal risks. Leader "Bird Sister" (Su Feifei), known for her influential blog posts on cracking challenges, ceased publishing related content by late 2017, signaling the end of the group's core operational phase.^[24] By 2018, 3DM had entered a dormant status with respect to cracking endeavors, and no major piracy-related activities have been reported since then, effectively concluding its era as an active warez group.^[9] The associated website continued as a legitimate platform for gaming news and downloads, devoid of infringing material.^[27]

Impact and legacy

Influence on piracy

3DM played a pivotal role in shaping Chinese gaming piracy culture by operating a major online forum that became a cornerstone for the warez community. The group's BBS platform facilitated the sharing of cracked games, torrent links, and localization efforts, enabling rapid distribution of Western titles to Chinese users who faced barriers like language and pricing. This user-centric model emphasized community collaboration, where members contributed to cracking, translations, and discussions, effectively democratizing access to PC games in a region with limited official availability.^[7] The forum's scale and activity influenced global piracy networks by promoting peer-to-peer sharing practices that extended beyond China. By hosting links to torrents and foreign cracks, 3DM's ecosystem encouraged similar decentralized distribution on international torrent sites, fostering a broader culture of collaborative warez exchange. This approach highlighted the power of online communities in bypassing traditional top-down piracy structures, inspiring user-driven scenes worldwide.^[7] 3DM earned a reputation as a "master troll" in piracy circles through provocative announcements by its leader, Bird Sister, which often disrupted group dynamics and sparked widespread debate. For instance, in early 2016, the group declared a year-long hiatus from cracking single-player games to assess piracy's impact on sales, a move that stunned the community and prompted reflections on the sustainability of warez activities. Such bold statements, including claims about cracking Denuvo-protected titles like those in 2014, not only challenged anti-piracy measures but also heightened tensions and rivalries among cracking groups globally.^[2]^[8]

Effects on gaming industry

The activities of the 3DM cracking group significantly influenced the adoption of advanced digital rights management (DRM) technologies within the gaming industry, particularly by demonstrating the vulnerabilities of earlier protection systems. As one of the most prolific groups, 3DM's ability to crack high-profile titles like Dragon Age: Inquisition shortly after release in 2014 prompted publishers to turn to more robust solutions such as Denuvo Anti-Tamper, which delayed piracy and protected initial sales windows.^[2] This shift increased development costs for DRM integration but was credited with reducing revenue losses from early cracks, with studies indicating that uncracked games using Denuvo could retain up to 20% more revenue compared to those pirated within the first week.^[28] However, the performance overhead associated with Denuvo sparked debates and player backlash, influencing industry discussions on balancing security with user experience.^[11] In China, where 3DM operated as a primary facilitator of game piracy, the group's efforts contributed to widespread availability of cracked titles at minimal cost—often under $2 compared to $60 for legitimate copies—severely limiting sales of Western PC games. This rampant piracy deterred some publishers from prioritizing simultaneous global releases, leading to delayed or region-specific launches to mitigate losses, while encouraging partnerships with local platforms like Tencent for better market penetration.^[29] Estimates from the era suggest piracy accounted for a substantial portion of potential revenue in the region, prompting strategic adjustments such as lowered pricing and enhanced localization to foster legitimate adoption amid economic growth and anti-piracy enforcement.^[30] 3DM's 2016 suspension of cracking single-player games for a year, announced by leader Bird Sister, served as an informal experiment to assess piracy's direct effect on legitimate sales, drawing industry attention to the economic dynamics of the PC market. Although formal results were not publicly detailed, the initiative underscored ongoing debates about whether rapid cracks cannibalize sales or serve as exposure tools, ultimately accelerating the evolution of anti-piracy strategies and contributing to a gradual decline in unchecked PC piracy as virtual storefronts like Steam gained traction in China.^[31]
