Passengers on The Ship can now send a free Guest Pass to a friend.
New and existing owners of The Ship will automatically receive one Guest Pass, which lets you invite a friend to set sail on the multiplayer murder mystery from Outerlight, Ltd. Upon receiving and activating the Guest Pass, the invited friend has 3 days of play available for free, with no obligation to purchase. After 30 days, we'll grant you another Guest Pass, so you can invite another friend to come aboard.
In addition, you can now purchase both the single and multiplayer versions of The Ship as one package deal, available for only $19.95. The multiplayer-only version is now available for only $14.95 (previously $19.95).
