From the very beginning of VALORANT development, we made it a priority to build out cheating resistance to ensure competitive integrity. In this article, I’ll walk you through one of these anti-cheat systems - Fog of War. This is one of VALORANT’s key security systems, which focuses on combating cheats that take advantage of a game client’s access to information, like wallhacks.

Hi, my name is Joshua Parker, and I’m an engineer on our Champions team. I help create the systems that unlock new capabilities for champions in League. Although my work is typically focused on how we build out a new champion, it also means revamping older systems and smashing tech debt along the way to help our engine evolve and allow us to keep creating new exciting experiences for players. In this article, I’ll describe the tech that went into reworking the League champion Mordekaiser.
Our technical interns worked with fellow Rioter technologists on everything from game engineering to developer tooling. Before they left, we asked some of them to share projects they contributed to, and to tell their stories of interning at Riot.
A whole new game means a whole heap o’ new technology. While we won’t be able to cover all of it in one go, I’d love to give you a glimpse at how we add features to LoR. I’ll describe our process of making it work so we can playtest it, move on to making it presentable using our suite of artist tools, tweaking it for balance, and finally making it shine by adding motion and sound before sending it out to players.
We’re the Esports Technology Group, and we’re responsible for the tech behind Riot’s biggest esports events, from reliable network connectivity to global broadcast capabilities to specialty tournament servers to the custom PC fleet used by pros. Part of our role at Riot is to approach typical broadcast and live production challenges with scalable and technology-driven solutions.
Hiya folks, Brian "Penrif" Bossé, your local friendly Tech Lead of League here. I'm taking some time in between matches of TFT to wax philosophic about game engines and how we on League make decisions around what direction to take our custom game engine. Join me on a moderately long look at one dimension of game engine design, where League currently exists on that dimension, and where we're taking the game from there.
Hi, I’m Tony, and I’m an engineer on League. This article is a followup to my performance series, where I talk about optimisation and profiling. This will be a high level overview of how we monitor game performance in League of Legends, how we detect when a performance degradation has slipped through QA and escaped into the wild, and how we track global trends in frame times over many patches and millions of players. I hope you enjoy it!
For the past 8 years, League has been using a patching system called RADS (Riot Application Distribution System) to deliver updates. RADS is a custom patching solution based on binary deltas that we built with League in mind. While RADS has served us well, we felt we had an opportunity to improve some key areas of the patching experience. We knew we could deliver updates much more quickly and more reliably by using a fundamentally different approach to patching, so we set out to build a brand new patcher based on content-defined chunking.
Hey there, my name is Riley “WhoaNonstop” Howsden, and I’m a Data Scientist who works on League of Legends, focusing mainly on personalization. Over the last few years I’ve been a part of the launch team for “Your Shop,” a product within League that creates personalized offers for every player around the globe. Data scientists like me work with engineers, analysts, artists, and publishing to create experiences that players love. From matchmaking and player behavior to artificial intelligence and game balance, data science is a key contributor for many initiatives at Riot.
So, why do Bug Blogs? Well, at Riot, we believe that a fundamental component of the development process is understanding that failures can and do happen. We make mistakes because we’re humans, and humans are far from perfect. And that’s okay! What’s important is to recognize failures for what they are, work to understand why they happened, learn from them, and make needed changes based on those learnings. That’s how we grow and that’s how we get better.
