Without weighing down the post with my opinion on Iceflake games..

I just cant see this being anything but a death call for Skylines II, and possibly the franchise.

On the 3rd of October 2025, the latest patch for Cities: Skylines II (version 1.3.5f1) went live. This is a free patch which is released to everyone who owns the game. The patch is live now on Steam. It will be live on Microsoft Game Pass as soon as possible.

• This patch addresses a security vulnerability within the Unity engine used by Cities: Skylines II (and many other games) that was made public yesterday

• This does not affect Cities: Skylines (2015) as the vulnerability is only present in more recent versions of the Unity engine

• Although there are no changes to the underlying code of the game that mods can interact with, mods which specifically target the previous version number of the game (v1.3.3f1) may display errors or warnings

• Although modders have been given access to the update to re-build their mods to target the latest version of the game, due to the urgent nature of security vulnerabilities the patch was published as soon as possible

• Please be patient. Everyone, even Cities: Skylines mod creators, has a personal life and might not be able to update a game mod immediately at launch. Do not bug creators to update their mod.

Please read the links provided by this thread carefully, and completely, to understand what you need to do to get your game working again.

🚨 How to keep yourself safe

• Unity state that there is "no evidence of any exploitation of the vulnerability nor has there been any impact on users or customers"

• Regardless, you should update your game as soon as the patch is made available to you via Steam or Microsoft Game Pass so that you receive the protection against this vulnerability

• The vulnerability can only be exploited if the game is running, so if you're currently playing you should close the game immediately and not re-open it until the update is applied

• You should not attempt to work-around or circumvent Steam or Microsoft's automatic updates to "keep playing with mods" as you will be exposing yourself to this vulnerability if you do so

Seriously, just update your game

Support for bikes

• Some assets are propped with the vanilla bike racks (which have been in the base-game since launch)

• It was confirmed in yesterday's Dev Diary that once bikes arrive in the game, these racks will become functional

• Therefore, the working assumption is that the bike racks in these assets will be functional too, once bikes are added to the game

saw this funny video, on-topic for this community so I thought I'd share

New train station assets by Rev0 have been announced! Source: Allianz pro Schiene on Instagram

Collaboration with Allianz pro Schiene & Deutsche Bahn AG

I'm very proud to announce one of the most important projects I've ever undertaken for the Cities: Skylines franchise, and a first in the city-builder genre. This has been in the works since 2023 and we've reached a milestone in the art development to be confident in showcasing the ongoing work with the public, especially at this moment in time - 'Tag der Schiene' - the annual Railway Days event taking place in Germany.

Allianz pro Schiene

Allianz pro Schiene is an NGO and the industry body for 24 non-profit organizations and 150 companies from the railway sector, focused on promoting the improvement of the railways in Germany. Together, they represent the interests of the public, the workers and the sector itself, working towards more environmentally friendly, efficient, and modern railways.

Bahnhof des Jahres

Railway Stations are more than just basic stops. They are the entry points of any city, a meeting place, and more; they each have a unique story to tell. Each year, the best railway station of Germany is picked by a jury, based on various factors such as environmental friendliness, accessibility and traveler comfort. Whether big, small or brand new, more than 5000 stations in Germany get to participate this yearly event... in Cities: Skylines

To celebrate the 20th anniversary of the competition, and for the first time ever, both DB and Allianz pro Schiene are making an entrance into a city-builder game.

From the list of previous winners, four stations were selected with the fifth being nominated by DB:

- Oberstdorf Station

Baden-Baden StationLutherstadt Wittenberg Main StationMannheim Main Stationand…

- Berlin Main Station.

All five stations, including props, are currently being recreated by yours truly. We are aiming for the most of the content to be released with the Cities: Skylines II asset editor and they will be available for free on Paradox Mods.

Youtube Showcase Special thanks to City Planner for taking the footage and testing the stations. He'll be using the stations in future so make sure to follow his Neu Dresden build! You can check the short trailer we created for you, linked above.

No Asset Editor or Console news: “Before we get into that, we know that many of you are waiting for news about the console release and the Asset Editor. While we don’t have any updates to share today, both remain important to us, and we’ll let you know as soon as we have concrete news to share.”

They replied this on the forums just a moment ago with some insight to the priorities they are working on right now.

TLDR: All hands are on deck for the release of the expansion Bridges & Ports; after that works resumes on other things.

Outakes:

Unfortunately, the Asset Editor related work has had to be pushed to the background while we have been focusing on other priorities. After the Bridges & Port related work, we will have the team tackle the remaining issues, and the asset editor for buildings will be released as soon as it’s ready.

The plan is currently to support building assets (and props) and expand the supported asset types in the future. Once we have established basic support for assets in the Editor, more complex asset types, such as vehicles and networks, can be worked on.

We’re currently working on:

   Fixing the issue with too few resources produced by offices being consumed, causing office company worker counts to drop to the minimum amount.

   Updating the production panel to provide a better understanding of the production and consumption of resources in the city.

   Rebalancing resource consumption to ensure all companies work as intended.

   Improving the water simulation and updating the maps to ensure they have water outside the playable area.

The reason we still call PDX mods beta is because the asset editor is missing, is not really any features related to PDX mods, its just to set expectations on modding in general.

More animations and updates to citizens are in the works but we do not have an ETA for when they’re ready for release. Similarly, bicycles are planned but on hold until Bridges & Ports is done.

Priorities after the expansion is released: Bicycles, Asset Editor, and more bug fixes.

My town currently has 4 highway on/off ramps. one on the far right (where the yellow and green lines start), one in the middle right above my industrial area, one in the middle left, between my farms/logging industry, and a 4th one off screen to the further left that goes to a seaport.

I would assume that traffic would follow the yellow line, using the offramps near their destinations.

instead, ALL the traffic coming into my city, is coming in on the far right and weaving through my surface streets (a 4 lane road, not highway, ring road, and 2 lane connector roads), causing massive traffic headaches and even bigger backups as they try to follow the green line to get to the far left through my city.

Why are my Cims dumb and bombing through the middle of my city, instead of taking the highway?

and another topic.. this torrential crush of vehicles coming in off that one far right offramp regularly causes huge backups for 4+ chunks on the right highway. I have lane mathmatics. I have a very long runup where they have plenty of time to get over. I still get idiot Cims taking the furthest lane just to get ahead of the crush before stopping and trying to merge in right before the offramp.

I miss TM:PE traffic lines.
