Not sure if this would count as a copy of an existing map or not, but I figured I'd try to submit it.
Why I think this map should win: The regular Face, in my opinion, isn't fit for siege. It's weird to defend, and most of the time the core is hard to attack. I completely redid the inside of the base, hopefully earning it some different and fun gameplay. Not to mention a whole new futuristic look and feel, including music.
