Due out in 2026.

Tencent Games subsidiary Grey State Studio have announced Rules of Engagement: The Grey State, a free-to-play “Horrorverse” first-person shooter / tactical RPG coming to PC via Steam and Epic Games Store, as well as WeGame in China. It will launch in 2026.

Here is an overview of the game, via its store pages:

About
You are a Strider: an elite operative hired by an enigmatic organization to venture Into The Grey State, an unstable dimension filled with horrific monstrosities and plied artifacts.
Your mission is simple: retrieve The Vertex, a priceless artifact from the heart of the anomaly, and survive a nightmarish, lawless frontier with rival squads Fighting for the same score.
This isn’t about saving the world. It’s just business.

A Horrorverse, Built to Expand
The Grey State is the most dangerous and lucrative gold rush in history. The twist? This frontier is a graveyard of nightmares—a “Horrorverse.” Think of any iconic monster from any movie, book, or creepypasta you’ve ever loved—chances are, something like that is waiting for you in there. This isn’t just one horror story, it’s all of them.

The Ultimate Hunt
Drop in, gear up, and get out. Rules of Engagement delivers a high-octane player-versus-environment-versus-player loop where every run is a desperate race against the clock.
The Prep – All squads deploy with only a basic loadout, igniting a frantic scramble to hunt grotesque creatures and scavenge powerful gear before time runs out.
The Showdown – As the final countdown begins, a critical choice emerges: will you leave early at a safe, personal exfil point for a guaranteed payday, or risk it all to hunt for The Vertex and fight for a seat on the heavily contested helicopter? The choice is yours.
Make the Build as Deadly as the Bullet
In the first Alpha Playtest, the game will feature three distinct classes, each a master of their craft with a sprawling talent tree that allows deep, creative build-crafting:
Sledge – An unstoppable juggernaut, forging a path with shield and hammer.
Pyro – A chaotic madman that controls the battlefield with fire and gas.
Phantom – A swift assassin that strikes from the shadows with extreme precision.
In Rules of Engagement, a clever build and smart team synergy can absolutely dominate pure mechanical skill. This is a game that respects player intelligence and rewards creativity.
Fair-to-Play, Never Pay-to-Win
Our business model is simple: the game is free-to-play, supported by cosmetic items only. You will acquire your gear purely via skill or luck. Player power cannot be purchased. Period.
