It seems that someone let some spurgu zombies loose near a military camp and the same individual seems to have forgotten that Finland has signed the Ottawa Treaty. Anyways there is a tent sauna and cold beer nearby so you should be fine.

There is also a non-functional button for leaderboards in the main menu, this is planned to be released at a later date. Planned statistics include at least zombie mode highscores and idk maybe the amount of consumed beer during a match, haven't given too much thought to that subject yet. Survived zombie mode wave highscores are tracked to your save file now so you can rest easy that your data is totally safe on your computer and ready to be synced when the leaderboards arrive.
There has been some confusion about how to unlock characters and that is totally on me, I forgot to add hints to just about every challenge. Lets just say that Finns love to go to sauna, fish and some like suicidal sports like extreme bike riding. The black metal dude likes Satan.
Anyways.
