Orcs Must Die Unchained expands again tomorrow as a HUGE update is planned and will bring with it, tons of new goodies.
The first big part of the update is that everyone is getting an account wipe, which includes friends list. However, gold will be refunded to players and those who have been playing for a long time will receive a gold bonus.
Next, the first version of the card grinder and Gib Store will be available. If you have cards in your inventory that you don't want, you can grind them into Gib's which can be used to purchase items in the Gib store.
Two new heroes will also be added to the game including The Kobold King
The Kobold King is short, dark, and regal. He enjoys long walks on the beach, sunsets, and PRESSING Q TO TURN ANY KOBOLDS AROUND HIM INTO MINIATURE KILLING MACHINES.
His turn-offs include seeing any kobolds die (each one killed near him increases his damage and movement speed for a short period of time) and being tied down (he is the fastest hero in the game and his second ability, Flee, breaks any CC for him and allies around him).
and Sir Winston
Sir Winston was father to eight famed paladins, all of whom fell in battle serving the Order. Unfortunately, such loss has proven too much, even for one as stoic as Sir Winston, and now he has become… somewhat upset with the Order.
Armed with a dark blade that weakens those it strikes, he can also curse minions and heroes (doing a pulse of direct damage to them that also heals his allies around the victim) and inspire mortal fear (preventing enemies nearby from using their abilities).
(PS, if you melee him you get weaker every time you hit him.)
There are four new skins including "Hidden Tiger" Midnight, "First Eye Blind" Stinkeye, "Royal Pain" Kobold King, and "Dark Paladin" Sir Winston.
There are tons of other updates as well including changes to card packs, and you can read all of the patch notes at their official website.
