Hitman....

Finally with some manoeuvring I got the final challenge, which in turn unlocked the overall challenge and marked all as complete.

With Colorado done I can move from the farm to the snowy mountain side of Hokkaido. Apt for the time of year. I've been to Hokkaido (in game) before with an Elusive target and the newer Patient Zero Campaign. That campaign has all but one challenge left.

Seems like a good starting spot; To finish that campaign before finalising the main campaign challenges on that map. I'm looking forward to it, it's a fun location.
