[Guide] ATS 1.55 – 100% Explored map with all DLC (with Iowa)
I explored 100% of Hawkeye State finally and in the video I’m sharing the guide how to do it on your side as well as tools and files. Text file with discovered items and fresh profile with opened map. Please note that these files are actual for current state of the game in August 2025 on ATS 1.55 and can be partially will work on later versions but always check if the new update available for this topic.
Obviously you need all map DLC and as always I would like to remind you to back up before doing anything with your profiles.

[August 2025] Stuck on 99.99% on Promods (1.55 update)
Since Promods 2.75 for ETS 2 1.55 was a compatibility release and we will see new areas only on 2.76, the status of my discovered items are actual and is still 99.99%. I’ve shared this progress on the ETS 1.54 but if you grab it on 1.55 you will get the same. Below you can also find the link to guide how to merge profiles.

Upcoming DLC for American Truck Simulator of Illinois State is probably will be released in 2026. I collected official SCS Software footages and pics to date.
Before Illinois we most probably will see another state DLC – Louisiana
Hidden Roads Study – August, 15 2025
As you may know I’m sharing periodically found hidden secret roads in both American Truck Simulator and Euro Truck Simulator 2. For now for Europe we don’t have new marked roads since the Greece release in 2024 and I assume until next map rebuilds (e.g. Scandinavia, Benelux) or map DLC like Nordic Horizon. But the other story with America where we got much more content to be discovered and after update in Missouri now we have also new secrets in Iowa. I guess I found all of marked secret roads in new state and will add them to the updated guide as well as couple easter eggs and pop-culture homages. It is a list of cities by states https://trucksim.top/y9t6 which won’t help you to find the roads but at least check if you missed any.
ETS2 (updated 04.25.2025, actual on 1.55, 80 roads so far)
ATS (updated 05.16.2025, actual on 1.55 without Iowa, 224 roads so far)
Unfortunately, YouTube search results often prioritize older videos, so even though I’m updating descriptions, outdated guides still rank higher in search results. Please always check if a more recent and updated guide is available.
All My Eurotruck Map Discovery Story
I decided to create a podcast-style episode about Euro Truck Simulator 2, focusing on its map expansions and my personal journey through the years and various versions of the game. Since version 1.55, one of the most challenging ETS2 achievements – Pathfinder – has undergone a significant change. Previously, obtaining this achievement required discovering 100% of the map, which was an incredibly demanding task. Now, you only need to drive 40,000 kilometers, which is much more achievable if you’re an active hauler. I actually earned this achievement back on March 7th, 2017, right after the Vive La France DLC release. This was during version 1.26, when the European map was considerably smaller than it is today.
Footages in the video taken from videos available on the channel, the latest one is for 1.54 – but if you see it later always check if the new updates available
If this video get at least couple thousand views (not sure it is possible) I will do the same for my American journey which is more saturated with DLCs.
