It's optional but if you want to see the animu playermodels:

1. download this zip https://up.heyuri.net/src/6047.zip
2. Find your svencoop folder by right clicking Sven Co-op in your steam library list then going to Properties -> Installed Files -> Browse...
3. Now in File Explorer find the svencoop_addon folder, then extract 6047.zip into svencoop_addon. You should now see a directory called 'models' in svencoop_addon
4. Launch Sven Co-op or restart it if it was already open, now in Options -> Multiplayer you should see the anime models in the selection

sorry for the last minute mod stuff - we can wait a little longer for every1 to get ready if theres any trouble
