Tundra Remix RR: unfinished B-Ball has never issued this map in this form.  After a little persuasion, he produced a version with snow on the ground, called Tundra Winter Remix, so we have a bit more to say on that particular page of the Reviws Array.  It is possible that B-Ball may issue a non-snow version as well, but the blue-white of the snow goes very well with the extremely slippery courtyard!
