Brass Rain is an authentic WWII co-op Shooter offering realistic recreations of major historical battles. Brass Rain delivers authentic locations, equipment, combatants, and tactics—and knowing your history will give you an edge.

In Brass Rain, players choose their faction and character, unlock authentic WWII weapons, uniforms, and upgrades, and take part in historically grounded missions, events, and campaigns in PvP and PvE combat. Brass Rain takes players from the beaches of Normandy to the skies over the Pacific, delivering iconic and authentic WWII battles with the same cinematic fidelity and emotional depth that define Yarnhub’s acclaimed films.

What sets Brass Rain apart is its seamless integration with Yarnhub’s cinematic universe. Before each major game update, Yarnhub will release a short film introducing new heroes, vehicles, battlefields, and historical context, giving players tactical insight and emotional connection before stepping into the action. This unique approach bridges storytelling and gameplay, allowing players to engage with WWII history on a deeper level while preparing for what’s ahead in the game.

The long-term vision is ambitious: to unite infantry, tank crews, bomber gunners, and naval teams in a single battle, delivering a fully integrated WWII experience across land, sea, and air. 

Shape the course of history with every decision you make on the battlefield!

Brass Rain will enter Steam Early Access in 2026, beginning with immersive, crew-based infantry combat grounded in real-world history.

Yarnhub, the animation studio behind high-quality 3D military history films with over 35 million monthly YouTube views, has entered the gaming world with its first title: Brass Rain. Backed by $2.9 million in equity crowdfunding from more than 5,000 passionate fans, Yarnhub is transforming its cinematic storytelling into an immersive WWII first-person shooter MMO.

Built by industry veterans and funded by its passionate community,  Brass Rain channels player demand into a bold, emotionally resonant experience, setting the stage for breakout success. Yarnhub’s game studio includes talent from Electronic Arts, Remedy, Jagex, and Sony, combining AAA experience with indie passion. Developed with a focus on quality and player experience, the team is committed to meeting the high standards set by industry veterans working on it. 

Founded in 2021, Yarnhub has built a global following of gamers and history enthusiasts through cinematic storytelling that celebrates military unsung heroes, tight-knit crews, and the emotional grit of brotherhood forged in battle. Now, that same community is at the heart of Brass Rain, a game developed for them and made possible by their support.

“Our audience has been asking for us to make a game for years,” said David Webb, CEO of Yarnhub. “They’ve told us exactly what they want: a game with heart, historical authenticity, global campaigns, and multiplayer combat that lets them fight as infantry, tank crews, bomber gunners, and naval teams. Brass Rain is our answer to that call, built from the ground up with the community in mind.”

Brass Rain will be free-to-play, offering some of the lowest-cost cosmetic microtransactions in gaming. This unique set-up allows the team to focus on delivering cinematic storytelling, authentic WWII battles, and a long-term version where battles will eventually span land, sea, and air in one unified gaming experience.  

“Brass Rain isn’t just a game, it’s a living historical experience shaped by the millions who watch our films every month,” added Cyril Barrow, Head of Games at Yarnhub. “Our community challenged us to go beyond what games like War Thunder and World of Tanks offer, by adding the one thing they’ve always wanted: boots-on-the-ground infantry. We’re delivering a fully crew-based combat experience that lets players fight together across land, sea, and air, and experience history as they go.”
