Unreal Fest kicked off yesterday, and NVIDIA made announcements around theavailability of PUBG Ally in PUBG: BATTLEGROUNDS’ new Ally Duo Mode, a new NVIDIA ACE Game Agent SDK, and new Unreal Engine 5 plugins.
PUBG: BATTLEGROUNDS’ new Ally Duo Mode Beta is available now through June 30th, via Steam. This introduces PUBG Ally, a highly adaptive, context-aware AI teammate that dynamically adjusts its playstyle based on your commands and emergent battlefield situations. It makes independent decisions such as looting, fighting and navigating to support you, all without requiring continuous prompting. Capable of understanding both voice and text inputs, from casual comments to tactical instructions, PUBG Ally possesses a deep knowledge of PUBG-specific terminology, player lingo, map locations, and item attributes. It works seamlessly alongside you to secure that coveted chicken dinner. Born from a collaborative AI research and development effort between KRAFTON and NVIDIA, PUBG Ally represents a new generation of AI game characters designed for deeper immersion.
NVIDIA RTX technologies are deeply integrated into Unreal Engine 5 through the NVIDIA RTX Branch of Unreal Engine and the DLSS Unreal Engine plugin. This provides developers with direct access to advanced rendering, frame generation, and ray-traced lighting.
Earlier at Unreal Fest, NVIDIA announced the new NVIDIA ACE Game Agent SDK and new suite of NVIDIA ACE plugins for Unreal Engine – read our blog for more details and additional news:
- The NVIDIA ACE Game Agent SDK is a lightweight, C/C++ agentic framework designed for seamless, native in-game integration. It is an open source, fully customizable solution optimized for small models and hardware-accelerated on NVIDIA RTX. Developers interact with the SDK through three core API categories – Agent API, Chat API, and RAG API. Together, these tools empower NPCs to dynamically perceive, reason, and act within the game world based on real-time player input. The tools have been used and battle-tested in real games, such as with the experimental in-game AI advisor in Total War: PHARAOH.
- A new suite of NVIDIA ACE plugins is now available for Unreal Engine 5 developers and technical artists. These plugins enable creators to implement live transcription, dynamic character dialogue, voice commands, and contextual action responses directly within their game logic. Unlike cloud-based services that suffer from high latency and unpredictable operational costs, these plugins offer local, RTX-optimized workflows bundled with ready-to-use models. These local, runtime AI models support both Blueprint and C++ integration out of the box, covering three pillars:
- Automatic speech recognition (ASR): Includes a ready-to-use English language model, nemo-conformer-ctc-120m, with download options for seven additional languages, a sample level, and Blueprint examples for rapid setup.
- Small language models (SLM): Provides local .gguf support, for low-latency text generation and function calling capabilities, optimized for immediate character dialogue and decision-making, also including a ready-to-use Qwen 3.5 4B model.
- Text-to-speech (TTS): Includes high-quality Chatterbox Turbo 350M TTS model, example voices, a sample level, and dedicated plugin content to bring characters to life instantly.
