- THE DARK SIDE OF CECLON One Year Later - 2 March 2026
One year later... Thank you 😃 It has now been a little over one year since the release of THE DARK SIDE OF CECLON. In the months following launch, several patches and improvements were released, bringing the experience closer and closer to what it was originally meant to be. Today, THE DARK SIDE OF CECLON has reached the point where it offers everything it was designed to deliver an open adventure meant to be explored, experienced, and ultimately completed. THE DARK SIDE OF CECLON was always intended as a complete, self-contained experience rather than an ongoing live service, and it has now reached that final state. For this reason, active content development for the game is now considered complete. This does not mean the game is being abandoned. The game will continue to receive patches if major issues or critical bugs are reported by the community, and it will remain fully playable…

- v1.0.11 [patch 11] - 3 July 2025
BUG FIXES - When Winged Nocturnes were defeated, and returned to the next dark night without having changed zones or left the game, they could no longer suffer damage. - Nocturnes could get stuck in walls or overlap with each other, pushing them off the nav mesh. Now, if that happens, they will reposition themselves to their last known position on the nav mesh. - When hovering over the sleep button on the rest bed, the dark night and normal night indicators didn't always update correctly. It was possible to see the next night marked as a dark night even though the current night was already a dark night in that case, the next one should have been a normal night.
- v1.0.10 [patch 10] - 21 June 2025
BUG FIXES - Proofreading of texts in English. - The blue arrows indicating that all acid clusters had been collected from an acid pool were reversed on some pools. This has been fixed.

Once upgraded, you'll be able to live again with better constants (health, hunger, thirst, etc.). - A tip has been added and a 3rd icon is now present in the window interface map next to the interference debugger and the light overcharged. CHANGES - The footprints have been slightly reduced in size. - The different levels of damage that the wallpass can sustain occur at lower speeds in the event of a collision. - All timers for the mini-game to open the hatch on the surface will be increased by 0.75 seconds. - There are now 2 icons for the interference debugger and the light overcharged on the window interface map, which when selected will display a descriptive text. This avoids constant text overload. - The objec…

- v1.0.8 [patch 8] - 11 March 2025
ADDITIONS - The vehicle (the wallpass) can now take damage when it collides with environmental elements at a certain speed. Additionally, the damage increases based on speed. Previously, only the Nocturnes could damage the vehicle. - The hidden black tiles on the map of the surface and underground now have a white outline. CHANGE - The dialogue after defeating Queen Nocturnes now includes an additional dialogue bubble for the combat drone, as one of the texts was too long for a single bubble. BUG FIXES - When the character transitioned from idle injured and deprivation condition there were no footprints at their location. Now, there are. - Proofreading of texts in English and French. - If we skipped the cutscene for the underground Primordial battles, the dialogue for Primordial 1 would always trigger. - The LODs did not fade gradually but all at once; this has been fixed. OPTIMIZATION…

ADDITIONS - Add details to the planet's surface, such as rocks, plants, tree and other details. - On the interface for choosing a time of day to sleep, you can now see on the UI whether the next night is a dark night or not.

Now, there are. CHANGES - The upper vertical limit of the camera position has been increased by 55%, allowing for a higher angle to better aim with the battle drone below. - The indicator point of the mini-game The Machina has been slightly moved. - The rock under the base generator pipe has been slightly adjusted in size and placement. - Some of the claw mark…

- v1.0.5 [patch 5] MAJOR UPDATE - 29 January 2025
ADDITIONS - Crystals surrounded by a sphere are now present on the surface and underground of CECLON. These crystals move as the player approaches, so you'll need to make contact with them to pick them up. They provide 1 more crystal than big crystals. - Floor icons have been added to the UI to indicate which floor the overloaded electric panels are on when the energy focuser is switched on. This was not very clear before. - When all the acid clusters in an acid basin have been collected, a validated icon appears on the relevant acid basin in the interface window map. - An oxygen capsule was added just after the bridge to be lowered. A cart was also added next to it to enhance realism. - The indicators that appear on the UI in the top right to show the floor and key elements are now displayed in all safe zones. CHANGES - The barriers in the platform phase to climb to the top of the base…
- v1.0.4 [patch 4] - 23 January 2025
CHANGES - The sound of the splash screen, where the auto-save indicator appears, has been softened. - The sound of picking up crystals has been softened. - All inputs requiring a button to be held down are now shorter and standardized across the board, except for a few very specific cases. - Areas containing acid clusters are now marked on the map. - Slight repositioning of an acid zone. - The icon for Trehium has been slightly increased in size on the interface window map. - The ticks from the incinerator on Nocturnes no longer occur every 1 second but every 0.75 seconds. - The incinerator's default damage per tick has increased from 25 to 300. - The Bunker turret' upgrades now significantly increase their attack speed.

- v1.0.3 [patch 3] - 20 January 2025
CHANGE - Some texture color changes have been made to the Winged Nocturnes. BUG FIXES - Due to a change, the heavy shot no longer dealt damage unless upgraded at least once. The penetration of the heavy shot will now decrease by 17 per upgrade instead of 25 because it initially dropped from 100 to 68. Upgrading it 4 times will therefore reduce it to 0. This means that enemies will take 100% of the damage, and even without upgrades, they will still take damage. - Reducing the damage multiplier of the shot from x3 to x2 when 10 light shots were fired caused the visual damage display to remain at x3 instead of updating to x2. - While inside the vehicle, the player could rotate the camera even if they were in the interface window or on pause. - Proofreading of texts in English. - In the undergrounds, if the player had a full inventory of water pipes while standing on the trigger for a water…
- v1.0.2 [patch 2] - 19 January 2025
ADDITIONS - You can now move the wallpass (vehicle) camera on the vertical axis in addition to the existing horizontal axis. - New text has been added to the UI "Wallpass console" and "Flashlight battery" when you are at the base (indicating important systems present in the base), specifically on the ground floor. - Added clarification in the info text about the ultimate merchandise in the interface window inventory ("light shot and heavy shot") to specify when the one-shot can occur. - An effect appears on the UI when the Fashir text is fully revealed. - In the final scene, the effects and certain details will differ, emphasizing whether you achieve the bad, good, or perfect ending. - Addition of 7 new achievements on Steam and Epic Games. CHANGES - Antic pearls have gone from 7500 health to 10000. - The x3 damage bonus for heavy shots after 10 light shots has now been reduced to x2. I…
- v1.0.1 [patch 1] - 16 January 2025

The icons on the map are now black until the previous one has been completed. - When not in nig…
- Demo [patch 7] - 22 December 2024
ADDITIONS - On the primordial original, during phase 4, a yellow orb concentrated with power will appear. It is larger than the orbs from phases 1, 2, and 3. Its damage zone will remain constantly active. It will move randomly, and both its movement speed and damage zone will increase as time passes, adding extra tension to this final phase. - Added details in the underground, such as grass, luminous organa (light), decaying miasm etc., to further enhance the environment. - Added new landmark on the surface, a big natural arch. - If the wallpass reaches a certain speed, it can damage Nocturnes if they collide head-on. - There are now a total of 4 containers on the CECLON surface instead of one. - Addition of a background to the bottom right of the interface window inventory. - Addition of one crystal on the surface. - The antic pearls now give off a vertical energy (an FX) that can be s…
