I've hosted most of these maps at some point in my personal server.
This is an insane amount of hard work, and this guy has looked for neither recognition nor financial support. It's admirable, and surprising that Tripwire hasn't made any of these official so far.

Hey Serious! I just wanted to say thanks for all the time and effort you put - and continue to put - into making all these creative maps! I've played about half of them and have enjoyed them all! I'm now in the process of trying the rest. Battleships and Path to the Void were particularly interesting (although River Canyon is overall favorite so far; it's the one I've replayed the most).

Thanks :)
Yeah, would be awesome if more servers would put workshop maps (including mine^^) in their list.

i really love your created maps man i hope your maps get more popular cause you deserve it

Cool Maps :D Very Fun
