Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We're building Echo Contingency as both a stealth game and a flexible framework for creating stealth scenarios, missions, and mods. Early Access lets us develop that foundation alongside the players who will actually use it.

Stealth games live or die on feel, clarity and trust. By releasing in Early Access, we can validate core systems (movement, visibility, sound, ai behavior, and co-op) while actively incorporating player feedback before those systems are locked in. ”

Approximately how long will this game be in Early Access?

“We expect Echo Contingency will remain in Early Access for roughly 12 months.

The exact length will depend on how the core systems mature and feedback from the community. Our focus is on reaching a state where the game feels complete, stable, and expressive rather than a targeted fixed v1 launch date. ”

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

“More missions, locations, and environment variety, deeper ai behaviors and stealth scenarios, expanded co-op mechanics and mission design options, and a more complete and polished modding toolset.

Early Access represents the core stealth sandbox and framework. The full version aims to build a broader depth and refinement on top of that foundation.”

What is the current state of the Early Access version?

“The Early Access version is fully playable and focused on the core stealth experience with initial modding tools available.

Players can expect:
* Functional stealth gameplay loop built around light, sound and line-of-sight.
* Precise movement and traversal designed for deliberate, skill-based play.
* Early versions of mission content and environments.
* Initial modding and content-extension capabilities.

Some systems are still evolving and players should expect ongoing iteration, balance changes, and new content as development continues.”

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

“We plan to gradually adjust the price over time as new content, features and tools are added.

Early Access purchasers are supporting the game during it's formative stages and our pricing strategy is intended to reflect that. ”

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

“Community involvement is a core part of how Echo Contingency is being built.

We plan to:

* Actively collect feedback through the Steam Community Hub and discussions.
* Share development updates and design goals openly.
* Use player feedback to guide balance, usability, and accessibility decisions
* Collaborate with modders and creators to shape tools, workflows, and documentation.

Our goal is not just to ship updates, but to build a shared understanding with the community about how the game works and where it's going. Early Access players aren't just playing early, they're helping shape the final experience.”

About This Game

Echo Contingency is a mod-first co-op stealth shooter built for players who miss the precision and tension of classic stealth design. 

There's no "easy-mode" stealth here. No mark-and-execute, no soft cover snapping, and no go prone to become invisible. Instead, every system is readable, explainable, and punishing but fair. 

Inspired by the feel, pacing and clarity of early 2000s stealth, Echo Contingency focuses on light, sound, stance, and movement discipline. Detection is never random.

Guards react based on real light levels, surface types, and how fast you're moving. If you get spotted, you'll understand exactly why. Metal grating echoes. Carpet absorbs. Water splashes. Every footstep is a decision.

The Dual-Meter System

Just like the classics, you always know exactly how visible and how loud you are:

  • Light Meter - Four graduated levels from deep shadow to fully exposed. Dynamically calculated from actual light sources. 

  • Sound Meter - Your noise level relative to ambient sound. Time your movements to machinery, rain, or ventilation to mask your footsteps. 

Five Analog Movement Speeds

Use the mouse wheel or analog stick to dial in exactly how fast you move. Each tier produces different noise levels based on your movement speed. Creep silently at tier 1. Sprint at tier 5 and everyone knows where you are. 

Designed for two, Playable as one

Every mission supports 1-2 players with online co-op (Steam P2P). Play with a human partner or an ai companion who follows your commands. The game is built for coordination. 

Synchronized Operations

  • Boost teammates to reach alternate routes

  • Disable cameras and laser grids while your partner moves

  • Share intel on patrol patterns and light sources

  • Hacking operations requiring coordinated timing

No Chaos. No Run and Gun. Co-op stealth fails when players "go loud". Success is found with methodical, tactical skill and timing. 

Split-screen local coop and 3-4+ player modded variants supported. 

Mod-first means YOU get the tools

Echo Contingency ships with the same mission-building and modding tools we use to make the base game. Modding isn't an afterthought, it's the core architecture. 

Three Tiers of Mod Creation

Tier 1 - Data Modding (No code) Tweak weapon stats, AI behavior, detection sensitivity, etc through simple data files. Change how the game feels without touching code. 

Tier 2 - Mission Builder (In-Game) Build complete missions using our block-based level editor. Place patrol routes, set objectives, define extraction zones, and share your creations through the Steam Workshop. 

Tier 3 - Full Modding SDK (For Power Users) Create custom weapons, AI archetypes, character models, levels, skins, and scriptable events using our Unity-based SDK and EchoScript (Lua) API. If you can imagine it, you can build it. 

Steam Workshop Integration

Browse, subscribe, submit, and play community-made missions and mods directly from the game. Rate and review. Build a reputation. Become the creator of the hardest stealth mission ever made or the most ridiculous. 

We know what killed stealth games. We're not doing that. 

  • NO Mark and Execute - Every take down requires positioning, timing, and commitment

  • NO Auto-cover system - You position yourself. You peek manually. You control exposure. 

  • NO "Go Prone to Win" - Prone is contextual (vents, ducts, etc) not a universal invisibility button.

  • NO Regenerating Health - Resources matter. Getting shot matters. Survive til you find a med kit.

  • NO Auto-Parkour - Manual traversal points. You decide when to jump, climb, or take the long way. 

  • NO Binary Detection - Graduated visibility and sound. Guards don't instantly know your exact location unless you really mess up. 

  • NO Cinematic Autopilot - The game never plays itself. Every action is your choice. 

Echo Contingency launches in Early Access with a focused, playable experience and a clear path to 1.0. We treat Early Access like a real launch with gameplay and modding tools right out of the gate. 

Your feedback shapes the game. 

For everyone who's been waiting for stealth to mean something again
