Drive growth and reduce costs with omnichannel business messaging

“PUBG New State” is live, and we couldn’t be more excited to power the chat experience of the year's most groundbreaking mobile game release! We are proud that Krafton chose Sendbird to enable in-game chat for what will be one of the most played games in the world.

What are battle royale games?

For those who may have missed the explosion of the battle royale genre in the last few years, these are popular online games where up to 100 players from around the globe pit themselves against each other in a struggle for survival. The players start with nothing and must explore an 8×8 km area to scavenge weapons and equipment. The last one standing wins!

The road to “New State”

PUBG Studios, a subsidiary of Krafton, is a game studio famous for having developed one of the seminal battle royale PC games, “PlayerUnknown Battlegrounds”. As the trend towards mobile gaming accelerated, Krafton produced a mobile version in collaboration with the Chinese company Tencent: “PUBG mobile”. Available on iOS and Android, it became one of the most-played mobile games.

A major hiccup along the way

When India banned “PUBG Mobile” due to rising tensions with China, Krafton had to devise a plan to bring back the popular game to its 50 million Indian fans. After taking control of the game’s intellectual property, Krafton built a brand new in-house version for India and launched the development of the sequel of “Battlegrounds”: “PUBG: NEW STATE”. The game transports us to 2051, in the once-thriving city of Troi, located on the outskirts of Lansing, Michigan.

Building live chat for more than 50 million pre-registered users

PUBG has created a dystopian world grappling with climate change, a pandemic, and a financial debt crisis. Building a complex immersive world was a vast undertaking, and on top of this, PUBG needed to make the game social and engaging for the fans. Krafton wanted to offer in-game chat and allow players to socialize in the waiting lobby as they prepare to play.

Battle games are social, and many players join their friends for fun regardless of their skill levels. Krafton realized they needed to rebuild chat from the ground up to meet their users' expectations. This meant engineering a complete communication infrastructure, and chat features to provide a world-class experience.

Picking the right chat provider

Delivering scale, performance, and reliability

After evaluating multiple vendors, PUBG Kraftonchose Sendbird. Sendbird offers the most feature-rich chat API and the most proven chat infrastructure in the market. With years of experience supporting many of the world’s largest brands, like Reddit and Paytm, Sendbird was the right candidate.

With over 200 million monthly active users, Sendbird has the know-how to manage vast and unpredictable traffic bursts while keeping the user experience flawless. Sendbird is so confident in its ability to scale that it never prevents chat message delivery, even if an application exceeds its plan quota.

Keeping chats relevant with tens of thousands of players in a channel

To create a strong sense of community, PUBG designed lobbies and a world channel where tens of thousands of players can hang out and interact with each other. Unlike squads that exchange fewer messages during gameplay, the flow of messages in these open channels can quickly become unreadable due to the sheer number of participants sending hundreds of messages per second.

Industry practice for managing large open channels has been randomly discarding a high percentage of messages to slow the flow. Deeming such a brute-force way of reducing traffic as unacceptable for a best-in-class modern app, Sendbird devised a new Dynamic Partitioning feature that divides participants into subgroups. The technique improves readability and creates a more cohesive, fast, and reliable conversation that drives a stronger sense of belonging for the players.

Reducing latency with the #1 chat cloud network

To meet global latency performance and privacy requirements, Sendbird developed the largest in-app chat cloud infrastructures, which expanded with our latest Canadian addition to 9 regions. For applications like “PUGB: NEW STATE”, where players from 200 countries can connect anytime, extended regional coverage is the only way to ensure the lowest latency for messages worldwide.

The 1st Unreal Engine chat SDK

When Krafton selected Sendbird, the only SDK we had for gaming was Unity. Krafton, however, uses Epic Games’ Unreal Engine. The Sendbird engineering team took on the serious challenge of developing the first version of the Unreal Sendbird chat SDK. It allowed Krafton to integrate chat with ease into its core gaming experience. Our new Unreal SDK is a private beta that creates a foundation to enable game developers to integrate the market-leading mobile chat engagement and communication platform in the future.

White-glove support

At Sendbird, we consider every interaction with our customers to be a partnership, bringing in-depth API integration and in-app communication expertise. From onboarding to data migration, architecture design, security, and launch planning, we are here all along the way to ensure our customers’ success. Also, our setup with offices over three continents and broad coverage of all time zones gave Krafton the confidence that its global launch could get the support it needed.

Let the fun go on!

After Krafton’s setback in India, the Sendbird team is proud to have delivered the privacy and performance capabilities that “PUBG: NEW STATE” required to extend its reach to players in 200 countries with ultra-low latency for gaming. As a loyal and committed partner, we wish Krafton the best of success!

To all the PlayerUnknown out there, we wish you loads of fun experiencing what is now the most exciting battle royale game across the entire mobile space.

A word of advice: don’t forget to chat with your teammates. The collaboration will be the key to your success!
