A new kind of squadmate dropped into PUBG: Battlegrounds on June 17, 2026 — one that doesn’t need a keyboard or mouse but listens to your voice and parlays tactical advice like a seasoned veteran. Krafton and NVIDIA have flipped the switch on the Ally Duo beta, a limited-time Arcade mode that pairs solo players with Ella, an AI teammate built on NVIDIA’s Avatar Cloud Engine (ACE). For two weeks, until July 1, anyone queuing into Sanhok on PC can experience the first major live test of a generative AI companion in a multiplayer shooter.

This isn’t a scripted bot that follows predefined waypoints. Ella is designed to understand natural language, process situational context, and respond with text-to-speech dialogue that feels dynamic. In the heat of a firefight, you might call out an enemy position, and she’ll not only acknowledge but suggest a flank, call for a vehicle, or alert you to the circle’s movement. The beta marks a pivotal moment for both PUBG and NVIDIA’s ACE platform — moving from tech demos at Computex 2023 to a real, playable game with millions of potential testers.

NVIDIA ACE: from stage demo to battle royale

NVIDIA first showed ACE in early 2023, wowing crowds with an AI-controlled ramen shop chef in a tech demo. The promise was enormous: generative AI that could give non-player characters (NPCs) the ability to converse, remember, and react intelligently without a human developer writing ten thousand lines of dialogue. By mid-2024, Convai, Inworld AI, and other middleware partners had toolkits ready, but no AAA studio had shipped the feature. Krafton, always hungry for innovation, saw ACE as a way to tackle one of battle royale’s perennial pain points: the solo-queue experience. Jumping into a squad without friends often means language barriers, absent teammates, or outright toxicity. A capable, cooperative AI could bridge that gap.

The version powering Ella relies on a subset of ACE microservices. NeMo Guardrails keeps her responses appropriate and on-topic, while Riva provides real-time speech recognition and text-to-speech. Crucially, the AI doesn’t simply generate words: it interprets the game state through an integration with PUBG’s internal systems. According to NVIDIA’s documentation, ACE can ingest map data, inventory, teammate health, and recent events to ground its responses. That means if you’re low on 5.56 ammunition, Ella might say, “I see an M416 back there — want me to cover while you swap?” It’s the difference between a gimmick and a genuine teammate.

The Ally Duo beta: what players get

The beta is exclusive to the Sanhok map, the tropical 4x4 that’s long favored for faster, more intimate engagements. Solo players select the Ally Duo mode from the Arcade tab, drop in alongside Ella, and face off against other human-AI duos. Krafton deliberately restricted the mode to this map to collect concentrated data on how players interact with the AI in varied terrain — dense jungle, open compounds, and the tight interiors of Cave Alpha or Bootcamp. The studio has said it will use metrics like voice command frequency, player retention, and win rates to tune Ella for a wider release.

From the early hours of the beta, community chatter on Reddit and Discord paints a… colorful picture. Some players report eerily human moments: Ella suggesting a rotation path that avoided a known hotspot, or reacting with what sounded like genuine relief when a teammate revived her. Others describe classic AI hiccups — misinterpreting a muffled command, or looting too slowly during a zone crunch. One popular clip shows a player telling Ella, “Take the UAZ and run,” only for her to reply, “I don’t see any enemies — are you sure?” before a Kar98 headshot ended their run. The jank is real, but so is the charm.

How Ella works under the hood

To avoid the latency that would make the feature unplayable, NVIDIA processes voice commands through a local speech-to-text model running on the player’s GeForce GPU. The transcribed text is then sent server-side to the ACE backend, which runs the large language model inference in the cloud. That response — along with any game-action triggers — returns to the client in under 500 milliseconds on a typical broadband connection. Krafton and NVIDIA recommend a GeForce RTX 30-series GPU or better, though the beta is playable on GTX 16-series cards if voice features are disabled. Players can toggle voice input on or off, with a fallback to a radial command menu for those who prefer silence.

The AI’s behavioral module is a hybrid of traditional utility-based AI and the generative model. Ella will still take cover, shoot, and loot using PUBG’s existing bot logic — but the decisions on when to push, heal, or share resources are influenced by the language model’s assessment of the tactical situation and the player’s expressed intent. This dual-layered architecture keeps her competent on a mechanical level while letting the ACE layer provide the strategic, communicative nuance.

System requirements and setup

Before jumping in, players need to enable NVIDIA ACE in the PUBG settings menu. The first time you launch Ally Duo, a setup wizard walks you through microphone calibration and prompts you to grant the app voice access. Krafton emphasizes that voice data is processed transiently: audio is transcribed locally and then discarded, with only anonymized text interactions logged for analysis. For streamers, a separate push-to-talk binding prevents hot-mic incidents on Twitch.

Hardware-wise, NVIDIA states that ACE voice features require an RTX GPU with at least 8 GB of VRAM for optimal performance. Cards like the RTX 3060, 4060, and above handle the load without sacrificing frame rates. On a test rig with a 4070 Ti, the AI overhead was barely 3–5 FPS in 1440p — noticeable only in intense firefights. Krafton has provided a dedicated “ACE Performance” setting that lets users allocate VRAM to the AI module separately from texture streaming, a smart touch that should ease concerns from the competitive crowd.

What this means for PUBG’s future

The Ally Duo beta is explicitly a test bed. Krafton hasn’t committed to a full rollout, but the two-week window suggests confidence. If Ella proves popular, the logical extension is a permanent AI Duo queue, possibly expanding to other maps. More ambitiously, ACE could enable AI squads where a player leads a full team of AI characters, each with distinct personalities. Imagine a four-man squad where your AI teammates bicker among themselves, learn your playstyle over multiple sessions, or even develop in-jokes. That’s the endgame NVIDIA has been pitching, and PUBG — with its high-stakes, emergent scenarios — is an ideal sandbox.

Of course, there are risks. Competitive integrity is paramount in PUBG’s esports scene, and an AI teammate that gives perfect callouts could be seen as an unfair advantage. Krafton appears aware of this: the beta is locked to the unranked Arcade mode, and Ella does not participate in ranked or custom matches. The studio has also stated that data from the beta will inform a “fairness pass” before any broader deployment. Expect heated debates about whether an AI teammate is more or less capable than a random human partner.

Community reactions: excitement and skepticism

On the PUBG subreddit, the top-voted thread is titled “Ella just told me to ‘trust the zone’ and then drove us into the blue.” The mix of awe and frustration is palpable. Post after post dissects her quirks: she apparently loves the VSS — a weapon many players ignore — and will sometimes offer her own meds when you’re low without being asked. But there are also reports of her freezing at critical moments, especially when the server is under load.

A moderator of the PUBG Discord summed up the mood: “It’s like playing with a very talented beginner who’s also a language model. Sometimes she’s brilliant, sometimes she’s drunk. But we’re seeing retention numbers we’ve never seen for an Arcade mode, so people are clearly hooked.” Data shared by Krafton during a developer livestream confirmed that Ally Duo queues are averaging 30-second wait times in NA and EU — a sign that curiosity is winning.

How to join the beta

Any PC player with PUBG: Battlegrounds installed can participate. Simply update the game on Steam or the Epic Games Store, navigate to the Arcade tab, and select Ally Duo – Sanhok. The mode is available 24/7 during the beta period, with no additional download or sign-up required. Players who complete ten matches with Ella receive a special “AI Companion” spray and a nameplate — a nice incentive to give the feature a serious try.

For those on older hardware, the mode still functions with the voice features turned off, scaling Ella down to a more traditional bot-like behavior. Krafton’s community managers have been active on official forums, gathering bug reports and feedback through a pinned survey. Early patches during the beta have already addressed issues like voice commands not registering in vehicles and Ella prioritizing loot over revives.

The bigger picture: AI in gaming

The Ally Duo beta isn’t just a PUBG experiment — it’s a signal flare for the industry. If a battle royale as fast-paced and unpredictable as PUBG can successfully integrate a conversational AI teammate, then RPGs, survival games, and MMOs are obvious next steps. NVIDIA’s ACE is designed to be game-agnostic, and partners like NetEase and Ubisoft have already shown prototypes. A successful beta here could accelerate adoption across the board.

For Windows users, the development underscores the growing importance of local AI hardware. The requirement for an RTX GPU isn’t just marketing fluff; the on-device speech recognition is what makes the latency acceptable. AMD and Intel GPU owners can play the mode, but they’ll miss the voice interaction — a tangible reminder that AI features are becoming part of the PC gaming value proposition. As Microsoft pushes its own Copilot+ PC initiative, we may see similar integration battles in the coming years.

Conclusion: a promising step, with many questions left

The Ally Duo beta is an ambitious, slightly messy, and genuinely exciting addition to PUBG. It gives solo players a reason to revisit Sanhok, offers a glimpse of a more interactive future for AI in games, and serves as a massive real-world test for NVIDIA’s ACE platform. Whether Ella becomes a permanent fixture depends on how the next two weeks unfold. Krafton needs to demonstrate that the AI can be both helpful and fair, while players need to decide if a synthetic squadmate is better than rolling the dice on a random human.

With thousands of matches being played every hour, the data flowing back to Krafton and NVIDIA is a goldmine. The question isn’t whether AI teammates will happen — it’s which studio will nail them first. For now, PUBG holds the crown, and anyone with an RTX card and a microphone can see what the fuss is about. Sanhok has never been more interesting.
