Does the game support LAN-multiplayer or only internet?

What he said. Because the answer is the difference between me buying it right now at either near or at full price (as of this typing it's 10% off) or waiting until it's on sale for <5 dollars.

Currently it's online only. The devs are adding a local splitscreen mode, but AFAIK no plans for a LAN mode.

Thank you for letting us know.

Victor Vran has no LAN lol
So I'll get "The Incredible Adventures Of Van Helsing" (http://steamcommunity.com/app/215530/discussions/0/864975632326502104/) instead.

That really sucks... Any developer knows that without LAN or singleplayer support their game will eventually die. Mean while other games live on years later because we can still play it. Hopefully there is an offline mode.

There is no always-online mode. As for local play a local coop will be added as an update, so 2 people could play on one PC.

I hope they do this at least. I prefer LAN so we can have our own screens, but either co-op method will work.
I sometimes wonder how developers test their games for multi-player?
If its an always online multi-player, they must have worked on a server connection from the beginning. I would think testing would happen offline in a private LAN environment.
