This isn't a request in anyway, just providing my work if you want to use it.
I made a new icon for BRUTAL-OXCE, not sure if Xilmi wants to use it.

https://openxcom.org/forum/index.php/topic,11814.msg161883.html#msg161883I used the same icon with different color schemes to match OXC. You are welcome to use them for OXC if you'd like, and no worries if not. The .ico file is a multi-resolution icon file with 16x16, 24x24, 32x32, 48x48, 64x64, 72x72, 80x80, 96x96, and 128x128.
