This is how I installed it:
1) Open Steam
2) On the top-left corner: Steam → Settings
3) Downloads → Steam Library Folders
4) Click the + button
5) Let me choose another location → Add
6) Select X:\Y, where X is the drive's letter of your choice, Y is a folder with a very short name (create it if necessary), e.g. SL (for Steam Library) - this to prevent files inside the mod's folder to have a path too long for Windows
7) Select Total War: MEDIEVAL II - Definitive Edition by checking the box on the right → Move
8) Select the folder you just created → Move
9) Optionally, navigate to X:\Y\steamapps\common\Medieval II Total War\ (or alternatively: Go to your Library → right click Total War: MEDIEVAL II - Definitive Edition → Properties... → Local Files → Browse...) to make sure that the files were moved successfully. If you're feeling paranoid, run the game
10) Download SSHIP 098 (and 7-Zip from
https://www.7-zip.org/ if you need to) - Personally, I downloaded the mod with JDownloader 2 (
https://jdownloader.org/): contrary to a standard download, it started instantly and didn't freeze my computer for the duration of the download
11) Cut (Ctrl+X) SSHIP_098.7z and paste (Ctrl+V) it into "X:\Y\steamapps\common\Medieval II Total War\mods", open the file, look at what greets you, then close the file
12a) If you were greeted by a single folder, then right click SSHIP_098.7z → 7-Zip → Extract here
12b) If you were greeted by a bunch of folders and/or files, then right click SSHIP_098.7z → 7-Zip → Extract in "SSHIP_098"
13) Optionally, either delete SSHIP_098.7z, or keep it for posterity / as backup (but in this case I'd suggest moving it somewhere else)
14) Optionally, rename the folder however you want (e.g. SSHIP_0.9.8 - notice the extra dots) - From now on I'll call this folder Z
15) Return to your Library on Steam → Click Add A Game on the bottom-left corner → Add a Non-Steam Game...
16) If you see the game, click the checkbox to its left → Add Selected Programs. Otherwise Browse... → Open "X:\Y\steamapps\common\Medieval II Total War\medieval2.exe" → Add Selected Programs
17) A new "game" named medieval2 should have appeared in your Library. Right click it → Properties...
18) Change medieval2 (the shortcut name) to whatever you want (e.g. SSHIP 0.9.8)
19) Change the target to the following:
Code:
"X:\Y\steamapps\common\Medieval II Total War\medieval2.exe" --features.mod=mods/Z
(i.e. click wherever in the target field, hit End on your keyboard, add a space, add --features.mod=mods/Z)
20) Use the new shortcut in your Library to play the game
