Just over a week to go.
From the campaign:
Just like that the Dwarven Siege Master is unlocked. This fearsome fighter is now available to add to your pledge for just $12. Thank you all again for your amazing support. This game would be nothing without you. Now we move forward towards the big push. The Orc Cavalry is only 5k away and we still have just over a week to go. Who knows what more we can accomplish before this amazing campaign is over!
