In September 2026, Krafton, the South Korean developer behind the global battle-royale game PUBG, issued a public apology after organised cheating by Vietnamese participants was confirmed at an international tournament. The episode has reignited a broader crisis of confidence in competitive e-sports, as several major sponsors have moved to suspend their backing.
What happened
At the heart of the scandal are allegations of match-fixing and the use of prohibited third-party software. Tournament administrators reportedly identified, through log analysis, evidence that Vietnamese players or teams had used cheat programmes including aimbots and wallhacks—tools that automate targeting or render walls transparent, giving users an illicit advantage. Krafton confirmed that an internal investigation had found multiple participants in breach of its rules, and responded by permanently banning those involved and nullifying certain results.
What makes Krafton's public apology notable is that it goes beyond acknowledging rule violations by individual players. The company has implicitly admitted failings in its own oversight of tournament operations—a significant concession, given that corporate apologies of this kind can carry legal liability implications and are rarely issued without careful deliberation.
The sponsors' retreat
The suspension of sponsorship by multiple companies is a telling indicator of how fragile commercial confidence has become in competitive e-sports. According to Newzoo, a market research firm, sponsorship revenue accounts for more than 60% of total global e-sports revenues. Given this structural dependence, the withdrawal of sponsors strikes at the financial foundations of tournament operations.
Industry insiders note that brands place brand image above all else. "Displaying your logo alongside an unresolved cheating controversy is itself a reputational risk," one observed. The pattern is not new: when a match-fixing scandal engulfed professional CS:GO teams in 2023, major sponsors froze or cancelled contracts within weeks.
Vietnam's e-sports ambitions, tarnished
Vietnam is one of South-East Asia's fastest-growing e-sports markets. According to Statista, the country had roughly 24 million gamers as of 2025, and the government has formally recognised e-sports as an official sport, extending institutional support to the sector.
Against that backdrop, the scandal deals a reputational blow to the Vietnamese e-sports community as a whole—even if that community bears no collective responsibility for the actions of specific individuals. Some experts caution against conflating the misconduct of a few players with a national failing. Yet they also point to a structural problem: the country's regulatory and supervisory infrastructure has struggled to keep pace with the sport's explosive growth. Vietnam's e-sports governing body, VIRESA, has reportedly announced it will conduct a parallel investigation into its own players.
A systemic problem, not an isolated incident
Cheating in e-sports is hardly a new phenomenon. Prohibited software use, account sharing, and match-fixing have been reported across major titles including League of Legends, Overwatch, and Valorant. A 2024 report by the International Esports Federation (IESF) found that the number of players sanctioned for cheating at major international tournaments had risen by an average of more than 30% per year over the preceding three years.
Ethics experts in the field point to two underlying causes. The first is the competitive pressure generated by large prize pools and lucrative sponsorship deals. The second is a supervisory gap created by the spread of online qualification rounds and other remote formats, which are far harder to police than in-person events. FairFight, a security software company, has acknowledged that whilst server-side detection technology has advanced considerably, hardware-based cheating tools continue to evade software detection in many cases.
Is Krafton's response sufficient?
Krafton's apology has been welcomed as an acknowledgement of responsibility, but critics argue that it falls short on concrete measures to prevent a recurrence. E-sports media analysts describe the public statement and permanent bans as reactive rather than preventive. What is urgently needed, they argue, is more rigorous identity verification of participants before tournaments begin, real-time behavioural monitoring systems, and the mandatory involvement of independent third-party auditors.
Riot Games' Valorant Champions Tour (VCT) is frequently cited as an industry benchmark, having established an integrated online-offline surveillance system supported by external security firms. Whether Krafton will use this episode as an impetus to introduce comparable institutional safeguards will be the crucial test of its response.
Rebuilding trust is a long game
E-sports marketing consultants expect sponsors to adopt a wait-and-see posture for "at least several months". The consensus is that sponsors will not return until Krafton has published the results of a transparent investigation, put verifiable anti-cheating systems in place, and demonstrated a track record of clean tournament operations in subsequent events.
For Krafton, the stakes extend well beyond this single incident. The long-term commercial value of the PUBG global e-sports ecosystem depends on competitive integrity. Tolerating cheating erodes audience engagement, which in turn depresses viewership figures, undermines advertising revenues, and accelerates the departure of sponsors—a vicious cycle that feeds on itself. The history of traditional sports, which have spent decades rebuilding credibility after doping scandals, suggests that restoring trust in e-sports will be no quicker a process.
This episode is not, in the end, simply a story about a handful of dishonest players. It has exposed structural weaknesses in the e-sports ecosystem that rapid growth had previously obscured. Tournament organisers, sponsors, players, and fans all share a stake in what happens next—and, accordingly, a share of the responsibility for what must be rebuilt.
