Inferno Protocol Known Issues & Fixes

Launch-week Steam Community activity already shows players asking about display, input, and startup problems. This page keeps those reports in one place until a single issue earns enough search data to become its own guide.

Use fixes cautiously: if the developer posts an official workaround, follow that first.

Status Labels

Label	Meaning
Officially fixed	A developer patch note or official post says the issue was fixed.
Community report	Players have reported the symptom, but the exact cause may vary.
Needs verification	The issue may be build-specific, hardware-specific, or not reproduced yet.

Current Issue Tracker

| Issue | Status | What players are seeing | First checks | | --- | --- | --- | | Cursor moves to a second monitor | Community report | Mouse does not stay locked to the game window while looking around | Try exclusive fullscreen, click back into the game, check monitor focus, and watch for official patch notes. | | Windows SmartScreen blocks startup | Community report | Windows warns that the app is unsigned or not recognized | Launch from Steam, avoid third-party files, and check Steam Community for developer response. | | Voice chat delay | Community report | Voice may become delayed during longer sessions | Check microphone device, Steam voice settings, in-game voice settings, and network stability. | | Microphone not working | Officially patched in demo, needs current-build verification | Squad cannot hear one player | Confirm Windows input permission, Steam input device, and any in-game microphone selection. | | Cannot move after Alt+Tab | Community report | Movement input can stop after minimizing or switching windows | Click back into the game, reopen pause/settings, switch display mode, or restart the session if controls stay stuck. | | Sprint or jump stops working | Community report | Sprint or jump may fail temporarily in a maze room or after interaction | Rebind/test input, leave and re-enter the area if safe, and record the room or trigger. | | Lobby or joining issue | Needs verification | A squad cannot join, host, or stay together reliably | Test a smaller lobby, restart the host session, and record region, player count, and invite method. | | Host-client visibility or sync mismatch | Needs reproduction; player-reported | A non-host client may report different maze visibility, missing maze marks, resource pickup problems, or chest/item results that do not match the host view | Record host/client role, build date, whether the report happened after the September 12 sync fixes, and whether restarting the lobby reproduces it. | | Head bob discomfort | Needs verification | A player asks for head bob or sway options | Check video/accessibility settings and watch for option updates. |

Resolved Issues Archive

Use this archive to separate patch-note fixes from symptoms that still need current-build verification. If a problem returns after the listed build, keep the old fix here and add a new dated report to the current tracker instead of overwriting the history.

Update	Patch-note area	Current handling
v0.55	Layer 3 entry, marker disappearance, teleporter behavior, generator gates, shovel loot, arrow pickup	Treat launch-week notes about those exact failures as outdated unless reproduced in the current build.
v0.57	Mixer recipe visibility, Water mark cleanup, ammo prioritization, Metal Scrap conversion, crafting output descriptions, Bunker 1 fixes	Recheck crafting, recipe, and bunker complaints against the current UI before publishing a workaround.
Sep 8 QoL update	Voice chat delay, server-side voice optimization, push-to-talk remapping, client joining or farming behavior	Recheck voice chat and joining reports in the Early Access build before marking them still active.
Sep 12 QoL update	Late-join timeout, clients far from the host breaking objects with arrows, rotating maze clipping, rotating maze item sync	Treat those official fixes as historical for the fixed symptom, but keep new host-client visibility reports separate until reproduced in the current build.
Swamp and Cave exits	Exit and navigation fixes referenced in September updates	If a player is stuck, compare the current route against the maze survival guide before assuming the old exit issue still applies.

Co-op Troubleshooting Order

Confirm everyone is using the same Steam Early Access build.
Start a small two-player lobby before testing a full six-player session.
Test voice chat, walkie-talkie behavior, sprint, jump, and camera lock before going deep into the maze.
If one player breaks, record whether the host or client had the issue, especially for host-client visibility, maze marks, resource pickup, chest rewards, and item sync.
Check Steam Community and patch notes before assuming a local fix exists.

Voice Chat And Microphone Fixes

In Windows, confirm the correct microphone is selected and allowed for desktop apps.
In Steam, open voice settings and test whether Steam receives microphone input.
In Inferno Protocol, check any proximity chat, walkie-talkie, or microphone selector before entering the maze.
If voice delay grows after 10-15 minutes, restart the lobby and record the session length, host region, and player count.

Cursor And Fullscreen Fixes

For a cursor that escapes to another monitor, test display modes in this order: exclusive fullscreen, borderless fullscreen, then windowed. After Alt+Tab, click once inside the game and check whether camera control re-locks. If that fails, restart the session and record monitor count, resolution, and whether the problem happens before or after opening menus.

Movement, Sprint, And Jump Fixes

If WASD, sprint, or jump stops responding, avoid blaming your keyboard immediately. First check whether the game window regained focus after Alt+Tab, whether a menu is still capturing input, and whether the same bug happens after reloading the lobby. Record the biome, room, co-op player count, and last interaction before the input failed.

When To Split This Page

Keep voice chat, cursor, and movement fixes together during the first launch wave. Split a dedicated page only when GSC shows repeated impressions for a specific query such as "Inferno Protocol cursor bug" or "Inferno Protocol voice chat not working."
