Basic Modding.
 

While the Game is in Early access and gets patched every other day, (and while the SDk wont be out until summer) there is not alot of point in committing to any serious modding just yet.
However, for those interested in having a look, you are able to make various perameter changes via a set of excel spread sheets found here:

C:\Program Files (x86)\Steam\SteamApps\common\UBOAT\UBOAT_Data\Data Sheets

Thank you for this interesting information. Can you give an example which parameters can be modified?

I can make a radio mod. But I cant found it where the music files are:hmmm:

I was looking for the same thing last night. Was gonna dump the Wolves of Steel files into station La Rochelle. Also, would be nice to add more stations. Those may e in the excel files.

For that^ (adding new files) you may need to wait until summer for the SDK.

I was tinkering with them sheets and althought I did mention this earlier in another post, here's the tip again.
:03:

So, I made a Guide few days ago.

Its on Steam thought.

It has information about editing those XLXS files
and little bit about the console in the game.

Have fun !
