Oh that's awesome to see.

I also got to know that the folks over at UGC are going to use Arctic for their next highlander season! :O
Guess I should get a new update out soon!
I do know that it will be the next map to be played in OZHL, due to popular vote from team captains.
also we found a glitch in the map when pugging it (we love to pug this map); it is possible to find yourself stuck in the ground next to the truck halfway between blue/red spawn and mid.
images here. it's happened more than once mid-pug, and can frustrate.
this happens on both blue & red side; i've reproduced it by, from the view of the second image as per above, holding left&fwd until stuck, then briefly heading right&fwd until stuck again, then mashing random buttons until you get in the position whe you can't actually get out. That may not be the way they get stuck, but it's proof of concept.
I hope that you continued efforts on this map will see rewards, it's a great map. we (in australia) may have gameplay feedback incoming; we'll need to butt heads for a bit and get back to you.
