Is This Better Than the Steam Version?

Let's settle the debate: Is the CODEX v1.7.2-f1 "better"?

Key Features of the v1.7.2-f1 Update

Before we discuss the download aspect, let’s examine why this version is so beloved:

  1. Monorails: The star of the show. Elevated, medium-capacity transit that connects residential zones to business hubs without taking ground space.
  2. Cable Cars: Ideal for steep hills (think San Francisco). They completely changed how players built mountain resorts.
  3. Ferries: Nautical transport that opened up island-building strategies.
  4. Blimps: A tourist-centric slow transit that adds flavor rather than utility.
  5. Intercity Bus Stations: Allowed outside connections to drop tourists directly into your local bus network.
  6. Roads with Integrated Transit: Bus lanes, monorail-integrated roads, and highway ramps that made traffic management smoother.
  7. New Scenarios & Achievements: "Traffic Giant" and "Splash Damage."

The v1.7.2-f1 patch specifically fixed a notorious bug where pedestrians would ignore ferries, as well as visual glitches with monorail pillar placements. It was the "polished" version of the Mass Transit era.

FAQ

Q: Can I transfer my save game from CODEX v1.7.2 to the official Steam version? A: Usually yes. Save files are located in %LocalAppData%\Colossal Order\Cities_Skylines\Saves. However, maps using DLC you don't officially own will break.

Q: Is there a virus in the CODEX Mass Transit Update? A: If you downloaded it from a public torrent site in 2025, there is a 50% chance it contains malware. Only scene-release archives (pre-database verified) are safe, but those are incredibly rare now.

Q: Why can't I find the CODEX v1.7.2-f1 update easily? A: Because CODEX quit in 2022, and most hosting sites removed their files to avoid lawsuits from Paradox Interactive.

Issue 3: "The launcher asks for a Steam code."

Fix: You forgot to copy the CODEX crack. Specifically, you need the steam_api64.dll from the CODEX folder. Anti-virus software often quarantines this file immediately. Restore it from your AV quarantine and add the game folder to the exclusions list.
