Major Update 0.7 - Smarter Enemies, After-Action Report & Lobby Control

In development — not yet released on Steam. Update 0.7 will sharpen enemy sight and hearing, add a native post-run after-action report, give hosts real launch-countdown control, and bring Steam update news into the main menu. The current public build is Update 0.6. Read the full site article.

Summary (in development, not yet released): Update 0.7 is planned as a major systems and interface overhaul. It will tighten enemy perception, makes co-op lobby launch flow easier to control, adds a stronger native after-action report, improves progression and save durability, polishes map readability, and brings Steam update visibility directly into the main menu.

Update 0.7 At A Glance

Smarter perception: forward sight cones, player-state visibility modifiers, and stronger voice/noise reaction.
After-action report: native post-run summary with a lobby return countdown and host-controlled continue flow.
Lobby launch control: hosts can cancel or skip countdowns, with clearer ready/start states.
Map readability: precise dungeon collision boxes and dedicated map UI collision volumes.
Save reliability: synchronous writes on manual, shutdown, restore, and end-of-run paths.

Smarter Enemy Perception

Stealth, movement, and voice communication now have clearer gameplay consequences instead of being cosmetic choices.

Visual detection respects a forward sight cone rather than letting enemies effectively see behind themselves.
Crouching, sprinting, stealth/noise multipliers, and active voice all feed into how noticeable you are.
Hearing stimuli from proximity voice and radio voice can push enemies into investigation behaviour.
Sight checks use stronger visibility traces and target-specific sight ranges.

Post-Run After-Action Report

A native full-screen run summary so the end-of-run report works even while Blueprint UI is being rebuilt.
Stronger success/failure copy, themed stats, mission and ribbon panels, and a lobby return countdown.
Hosts can continue to the lobby early, while automatic lobby travel still happens after the timer.

Lobby Launch Control

Hosts can cancel an active launch countdown from Ready and skip it from Start.
Ready/start button labels, tooltips, and enabled states reflect countdown state.
Leaving the lobby during countdown cancels launch before session teardown.

Map Readability & UI Accessibility

Dungeon modules can provide dedicated map UI collision boxes for cosmetic map shape data.
Map generation uses precise multi-box room shapes, prunes broad aggregate boxes, and closes tiny visual gaps.
A managed tooltip system adds a native fallback tooltip tree plus settings for tooltip visibility and scale.
Polish passes across progression, leaderboards, photo gallery, host game, run summary, and the main menu.

Save, Progression & Steam Reliability

Progression and run results are far less likely to be lost around map travel, shutdown, Steam/offline transitions, or manual save actions.

Synchronous byte-payload saves for critical manual, shutdown, restore, and end-of-run paths.
Coalesced save flushing can be forced synchronous before shutdown or critical progression writes.
Local fallback Steam IDs are validated more strictly and written synchronously.
End-of-run persistence flushes pending save data before final progression snapshots.

Patch Notes (0.7)

Added a native Steam updates widget to the main menu for patch notes and build news.
Added a native post-run after-action report with lobby return countdown.
Reworked enemy perception with sight cones and player-state visibility modifiers.
Added host launch-countdown control plus clearer ready/start feedback.
Improved map shape accuracy and added a managed tooltip system with accessibility settings.
Hardened save, progression, and Steam persistence with synchronous critical writes.
Fixed electric puzzle entry so the initial interact prompt is more forgiving.

Build spotlight - v0.6

Major Update 0.6 - New Puzzles, 3D Terminals & Spectator Overhaul

Published on February 28, 2026, Update 0.6 adds four new puzzle types, moves puzzle play into world-space terminals, improves spectating, and hardens multiplayer stability across live runs. Read the full site article.

Steam summary: Update 0.6 is a systems-heavy milestone focused on deeper co-op puzzle play, cleaner spectator flow, stronger late-join reliability, and a more consistent update cadence going forward.

Update 0.6 At A Glance

4 new puzzles: Circuit Breaker, Lights Out, Circuit Trace, and Circuit Reroute.
World-space terminals: puzzles now live on in-world screens instead of feeling detached from the level.
Spectator upgrades: better readability when teammates are solving active interactions.
Multiplayer sync: late joins, shared puzzle state, and interaction reliability all got stronger.
Core stability: broader integration work landed across AI, sessions, missions, HUD, and save-state systems.

New Puzzle Content

Steam positions 0.6 as a co-op depth update, and the new puzzle lineup reflects that. Each one pushes clearer callouts, shared problem solving, and better variety across repeated runs.

Circuit Breaker: balance breaker loads until the target power is exact.
Lights Out: a grid logic puzzle where every switch can cascade into the rest of the board.
Circuit Trace: route power through the right relay nodes and legal paths.
Circuit Reroute: rebuild stable flow through reroute nodes under pressure.

3D Puzzle Terminals

Puzzles now appear on in-world terminal screens instead of reading like a detached overlay.
Teammates can track live puzzle state more easily during tense moments.
The overall read is more immersive, clearer in motion, and better for squad coordination.

Spectator Overhaul

Cleaner spectator HUD for less visual friction when you are out of the run but still following it.
Puzzle-aware viewing so spectators can understand what active players are doing.
Smoother switching flow when moving between viewed teammates.

Multiplayer, Stability & Performance

Improved replication for puzzles and shared interactions.
Better late-join consistency for runs already in progress.
Packaged-build fixes for respawn and objective spawn edge cases.
A wider integration pass across AI, lobby flow, dungeon systems, missions, HUD, and save-state pipelines.

What Comes Next

The Steam post also resets expectations for the cadence after the 0.5-to-0.6 gap: smaller updates, faster follow-up fixes, and continued work on deeper AI, more puzzle variety, and progression UX.

Patch Notes (0.6)

Added four new puzzle types to expand co-op problem solving.
Introduced world-space 3D puzzle terminals for more readable in-level interactions.
Overhauled spectator flow with cleaner viewing and better puzzle awareness.
Improved multiplayer sync, shared-state consistency, and late-join behavior.
Shipped a broad stability and systems integration pass across core gameplay layers.

Major Update 0.5 - Combat-Ready AI, New Puzzle, Voice Chat & More

Smarter enemies, a brand-new electric puzzle, onboarding improvements, and voice chat upgrades headline Update 0.5-setting up a massive December follow-up.

Summary: Sharper AI, new electric puzzle, visual upgrades, improved onboarding, environment overhaul incoming, and major December systems update. This is a large monthly patch with even bigger updates on the way.

Enemy AI - Now Fully Dangerous

Change	Detail	Why it matters

New Puzzle - Electric Switch Challenge

Toggle switches to guide twin mechanical dials into a "sweet spot." Every switch influences one or both dials, turning math, timing, and communication into high-stakes coordination.

Mechanic: Switches alter dial values independently or together; align both to win.
Teamplay: Built for callouts-players track values and timing together.
Tension: Enemies and hazards can interrupt progress, forcing resets.
Replayability: Switch effects vary by seed for procedural difficulty.

Voice Chat Improvements

Lighting passes add deeper shadows, cooler tones, and clearer interactables.
Subtle post-processing tweaks and new decor improve room-to-room variety.

A new User Widget Guide explains controls, objectives, pinging, and puzzle basics the first time you load a map. It stays put until dismissed and can be re-opened from the pause menu.

Progression System - In Development

Backend systems for leveling, XP tracking, and rewards are live. UI and unlock surfacing land next update.

Additional Improvements

Ambient sound logic: cleaner transitions between default, proximity, and chase states.
Menu sound system: rotating loops plus new one-shots for richer ambience.
