The aim of this guide is simple – explanation on how to apply mods to this game. It also includes an archive with every mod I was able to find.
Applying the mods
Now go to the “Local Files” tab:
And choose the option “Browse Local Files”
You should be seeing something similar to this:
Now, you may notice I have one extra folder in there, that being the folder named preview. That is the folder you must create in the general Space Marine folder you’re currently in, and where you’re going to be putting the mods. It’s quite literally a copy/paste operation – you grab the contents of the preview folder of the mod you want to use and you paste them inside your preview folder. Or, if you’re even lazier, you can just copy the mod preview folder and merge it with your preview folder.
Note: It’s normal to get a pop-up window that asks you if you want to merge folders when applying multiple mods. If the mods themselves affect different things – for example you want to use both a mod that replaces the bolt pistol with a storm bolter and a mod that replaces the power axe with a power sword – there will be no issue, as the mods modify different files.
However, if you try starting the game now, nothing will change. That is because you need to tell Steam that you want to use the mods. To do that, you need to open the “Properties” menu again and choose the “Set Launch Options” option from the “General” tab:
The command you need to set is “-usepreview”:
Note: This will disable the multiplayer of the game. No progress, achievements or unlocks will be lost, but I had some issues with one of my saved skins that forced me to re-create it from scratch – I tinkered a bit too much with one mod, mostly trying to make it work with another one that affected the same files. If you don’t try such shenanigans, you should be fine. Also, if you want to be able to play multiplayer again, simply remove the usepreview command. Of course, this will disable any mods you have applied.
If you’ve done everything proper, Steam will read any files you have in your preview folder and apply them to the game.
Anyway. I’ve compiled my findings in this archive. It may take a while to download, as it’s around 300 MB. I’ve tried including screenshots and installation instructions for each mod, however the ones that are more decently made already had them, and for some it’s simply not required as they’re self-explanatory.
