Internet connection required at all times.

Since it is mentioned in the last requirement that the internet connection is required all the times, so probably the open beta couldn’t be played in offline mode. Not sure whether there is an single player skirmish mode in the open beta as I am still downloading at the time of writing. If the game is good, I might write a review on it.

So what are you waiting for? Go claim you beta key now, Commander!
