What the developers have to say:

Why Early Access?

“The Crimson Contract is built around a 7-Act world. We are launching with the first two Acts because the core game loop, multiplayer, weapon mechanics, enemies, and progression are all right about where we want them. We want the next five Acts and the social and meta-game systems around them to be shaped by the players who are actually putting hours into the game. Early Access gives us an engaged community to design alongside, instead of guessing in isolation.”

Approximately how long will this game be in Early Access?

“Roughly one to two years. We are pacing the remaining five Quarantine Zone Acts at least three months apart, with smaller social, customization, and content updates landing between them.”

How is the full version planned to differ from the Early Access version?

“The 1.0 release will include all seven Acts. Each new Act introduces a new Quarantine Zone map, a signature boss, new regular enemies, and new weapons and gear.

Between Act releases we plan to ship the social and meta-game features that round the experience out, including:

* Public lobby browsing (Early Access ships with Steam friends and friends-of-friends invites)
* Modular character customization
* Weapon attachments
* Daily and community-wide challenges
* More achievements and leaderboards
* Unlockable NPC characters
* Custom control mapping and accessibility features

A few additions, such as voice-over, are still under evaluation and may be put to a community vote along side various aspects of the previously stated items.”

What is the current state of the Early Access version?

“The Crimson Contract at Early Access launch is a fully playable 1 to 4 player online co-op zombie survival game. Players get:

**Maps and modes**

- 1 to 4 player online co-op via Steam (friends and friends-of-friends invites)
- Two of the planned seven Quarantine Zones: BLACKWOOD (Forest) and MILLHAVEN (Town)
- Four difficulty tiers per map: Easy, Medium, Hard, and Last Stand (Last Stand is our endless mode)
- A tutorial Quarantine Zone for new players

**Combat and content**

- 13 weapons spanning handguns, shotguns, SMGs, assault rifles, snipers, and melee, most of which are earned through gameplay progression rather than handed out at the start. Heavier weapon classes (LMG, Rocket Launcher, Flamethrower, Minigun) arrive in later Early Access updates.
- A roster of zombie types tuned to each Quarantine Zone, including the signature bosses Horned Beast (Forest) and Wretch (Town)
- 9 tactical consumables: Music Box, Smoke Grenade, Barricade, Mine, Grenade, Sentry, Nuke, Health, and Stamina
- 7 provision upgrade types (Health, Stamina, Self-Revive, Speed, Damage, Rate of Fire, Armor), unlockable through Forest and Town progression at two tiers each at launch, with deeper tiers opening as later Quarantine Zones release

**Persistence and competition**

- 33 Steam Achievements at launch (with 4 more tied to weapon classes that activate as those weapons release through Early Access)
- 48 Steam Leaderboards at launch covering per-map kill counts at every difficulty, weapon-class kills, zombie-type kills, accuracy, total earnings, highest round reached, and more (additional per-map leaderboards activate as future Quarantine Zones release)
- Lifetime stat tracking across sessions
- Cross-device cloud save

**Other**

- Full controller and keyboard-and-mouse support, with on-screen prompts that match the active input device
- Server-authoritative anti-cheat protecting the in-game economy
- English text and UI at launch

Will the game be priced differently during and after Early Access?

“We plan a modest price increase when the game reaches 1.0 to reflect the additional content delivered during Early Access. Players who buy during Early Access keep the lower price and receive every Act update at no extra cost.”

How are you planning on involving the Community in your development process?

“Several channels:

* A Discord server for direct, ongoing conversation between players and the dev team
* An active presence on Facebook, Instagram, TikTok, Reddit, and YouTube, with content tailored to each platform
* A public roadmap with regular updates so players can see what is coming and what is currently being worked on
* Public lobby browsing and daily / community challenges, which create natural spaces for the community to form in-game
* Steam Achievements and Leaderboards for visible long-term goals
* Community polls on features we are undecided about, such as voice-over and customization scope
* Patch notes and dev posts that tie back to player feedback so contributors can see their input land in the game”

About This Game

The outbreak wasn't contained. It was covered up. 

Quarantine zones have fallen. The infected are spreading. And the people responsible for stopping the collapse have run out of options.

That's where you come in.

As a contracted mercenary, you'll enter dangerous containment zones alone or with your squad to complete high-risk missions, recover valuable resources, and survive overwhelming waves of infected. Every contract is a gamble — push deeper for greater rewards, or extract before the quarantine zone becomes your grave.

Start with basic weapons. Build devastating loadouts. Unlock powerful upgrades. Call in support abilities. With every mission, you'll become stronger... but so will the threats waiting for you.

The deeper you venture into the infected zones, the more you'll discover that something is wrong.

The outbreak was never just an accident.

You aren't here to save the world.

You're here to survive.

You're here to get paid.

You're here to uncover the truth behind The Crimson Contract.

Key Features

Squad Up or Survive Alone

Build Your Ultimate Zombie-Killing Arsenal
Start with basic weapons and become a walking apocalypse. Upgrade your gear, unlock powerful abilities, and create devastating loadouts tailored to your playstyle.

Push Your Luck. Extract or Die.

Every contract is a gamble. Choose your equipment, manage your resources, and decide when to escape. Stay longer for bigger rewards... but risk losing everything.

Built for Co-op Chaos

Designed for keyboard, mouse, and controller players, The Crimson Contract delivers seamless squad-based action whether you're fighting alone or with friends.
