Within the U-boot sensors GR2 there is a Searchlight that looks like it could be an upgrade, and there is also files relating to it in the games files, It would be cool to have a searchlight when attacking merchants that are un-armed, to help with identification.
Also within the GR2 is this strange T shaped Apparatus.
I'm not sure what it does or what it is.
I would really like to have a searchlight on my U-boat
