How to Play Competitive Games on Linux in 2026: Anti-Cheat Guide

Playing competitive games like Fortnite, developed by Epic Games, or Valorant, developed by Riot Games, on Linux in 2026 requires understanding how specific anti-cheat systems interact with the SteamOS and Proton environments. While many titles now function seamlessly, others remain inaccessible due to how their security software handles system-level permissions.

To determine if your library is ready for Linux, follow these steps:

1. Verify if your preferred titles utilize kernel-level anti-cheat software.
2. Install the "Proton EasyAntiCheat Runtime" via your Steam library.
3. Install the "Proton BattlEye Runtime" via your Steam library.
4. Check verified compatibility lists for specific game status on Linux/SteamOS.
5. Ensure your Linux distribution is supported, as some titles only whitelist SteamOS.

Understanding Anti-Cheat Compatibility on Linux

The primary barrier for Linux gaming in 2026 remains the integration of security software. Unlike Windows, which allows many anti-cheat solutions to hook directly into the kernel, Linux restricts this level of access. Because many anti-cheat systems, such as Easy Anti-Cheat, BattlEye, Valve Anti-Cheat (VAC), Anti-Cheat Expert (ACE), EA Javelin Anticheat, Nexon Game Security, RICOCHET Anti-Cheat, and NetEase Game Security, rely on kernel-level monitoring, they often block Linux environments entirely.

At In Game News, our coverage of platform migration highlights that even when a game is technically capable of running through Valve’s Proton compatibility layer, the anti-cheat module may still trigger a block. This is why you will find that some titles work perfectly on SteamOS while others remain strictly off-limits.

Which Anti-Cheat Systems Work with SteamOS?

SteamOS, the operating system powering the Steam Deck, has seen significant improvements in anti-cheat support. Developers have the ability to toggle support for Proton, which acts as a bridge for Windows-based games. When a developer enables this, the game can communicate with the necessary anti-cheat runtime installed on your system.

It is important to distinguish between native Linux builds and games running via Proton. A native Linux version of a game might handle anti-cheat differently than its Windows counterpart running through Proton. Always check the specific requirements for your version of the game before attempting to launch it in a competitive setting. You can find more information on our Linux gaming coverage to stay updated on these technical shifts.

Managing Runtimes for Competitive Play

For players looking to maximize compatibility, Steam provides dedicated runtimes that act as the middleman between the game and the operating system. You must ensure that the "Proton EasyAntiCheat Runtime" and "Proton BattlEye Runtime" are installed in your Steam library. Without these, games that rely on these specific security suites will fail to launch or will immediately kick you from servers.

Be aware that some games apply restrictive policies that allow the game to run on SteamOS but block other desktop Linux distributions like Fedora or Ubuntu. This is a deliberate choice by the developer to limit the environment to a known, controlled hardware set like the Steam Deck.

The Risks of Bypassing Security Measures

One of the most common questions we receive at In Game News is whether there are ways to circumvent these blocks. The answer is a firm warning: never attempt to bypass or modify anti-cheat software. Doing so is a direct violation of the terms of service for almost every major publisher. Attempting to force a game to run by modifying files can lead to permanent account-level bans across all platforms, not just on Linux.

While there have been rare instances of Linux users receiving false-positive bans, these are typically addressed and reversed by the developers once the issue is identified. However, relying on these reversals is not a strategy. Stick to games that have official support for Linux to ensure your account remains in good standing.

Verifying Game Support

Instead of guessing which games work, we recommend using curated, community-driven resources. Because the status of anti-cheat support can change with a single patch, relying on real-time data is essential. We monitor these changes closely to provide the most accurate picture of what is playable. If a game is not officially listed as supporting Linux anti-cheat, assume it will not function until the developer explicitly updates the game's security configuration.
