What is the DRM on Warriors of the North?

[Roman]

Hello all, I bought King's Bounty: The Legend a few months (that's how long word of mouth took to reach me ) after it came out and loved it. Now that Warriors of the North is out, I am interested in buying it too, but before I do, I would like to ask about the type of DRM it employs. I have a strict policy against buying games that use online-based DRM, due to the fact that it makes playing (or installing/activating) the game dependent on external servers that can be shut down later. I don't mind DRM that is uses things like disc checks (which is what King's Bounty: The Legend had and why I could buy it).

With this in mind - does Warriors of the North use DRM that is dependent on external servers? Thanks!
