Leaked (poor quality) gameplay videos have emerged. Whoever made these videos is of course breaching the NDA for the alpha, but they are entertaining to watch nonetheless. We see an early glimpse of the leveling process and what rewards are earned.
The gameplay features a single player game mode which takes place in Old Russia.
Talk about this and more on our community forums.
Update: It seems that all of the videos have been taken down. If more links are found I will post them here.
