Chernobyl: Simulator

Don't forget to reset your key binds in settings.MultiplayerThe unit can now be operated as a crew. Run the control room together with other players instead of alone either by joining our official dedicated server or hosting your own co-op game!The multiplayer includes chat (ENTER/T), voice chat (V) and gestures (G). In-Game FeedbackYou can now send feedback, bug reports and suggestions directly from inside the game, without leaving the sim. You can include game log and loaded game state as well to better diagnose the reported issue.Shared SavesEvery save can now be shared with a short code. Copy the code, send it to another player, and they can load your exact scenario — useful for reproducing a bug, handing over a running unit, or setting up a challenge for someone else.

Command Console & ConVar SystemThis update introduces a full console and configuration system in the style of Source-engine games like Counter-Strike. Press F1 to open the in-game command console, bind any command to any key, and tune the game through plain config files (keys.cfg, autoexec.cfg) in the game directory. Hundreds of fine-grained parameters are now exposed as convars — every command and binding is documented on the wiki. SKALA / PRIZMA ReworkThe SKALA/PRIZMA computer has been heavily reworked. Many more parameters are now available to query, including basic setpoint monitoring. MTK displays now behave like the real hardware: they report slightly stale data and refresh less frequently, reflecting the actual cycle time of the PRIZMA program on the original machine. See the wiki for the full list of available inputs. New Reactor Core Thermal FeedbackThe reactor core received a new set of thermal feedback mechanisms for much more realistic behavior:Positive void coefficient of roughly +4.1 βeff, close to the historical valueAdjusted Doppler (fuel temperature) feedbackNew graphite temperature feedbackWater temperature feedback in control rod channelsGas-gap conductivity

This update focuses on performance, usability, and stability. VRAM usgae has been reduced by approximately 75% through extensive texture optimizations, the user interface has been completely redesigned, and save management has been improved with support for non-destructive sub-saves. Numerous bugs have been fixed across Windows and macOS, several simulation systems have been corrected to better reflect real-world behaviour, and visual consistency has been improved throughout the control room.Breaking ChangesAR-1, AR-2, and AR-M's Measurement and Execution switches now correctly select the required number of channels for AR operation (3 or 4), matching real-world functionality.ImprovementsOptimized textures to significantly reduce VRAM usage (from approximately 8 GB to ~2 GB).Completely revamped UI, including:Main MenuSettingsLoad GameDialog WindowsTask ListIntro DialogAdded descriptions for every setting option.Updated and improved translations.Reworked save management: saving the game generates a new save file instead of overwriting the previous one. Old saves can be pruned though Load page.Retextured wall panels to use a single tileable texture, reducing GPU memory consumpti
