Arcen Games has been pretty quite the past few months, but for good reason. They've recently announced that they're in the home stretch of development for A Valley Without Wind 2. The game has just recently moved into a short private-alpha that ends early next week, after which it'll be going into open beta for PC and Mac users. Those who pre-order the game will get instant access to the latest beta build.
On top of that, those who have purchased the original A Valley Without Wind will get the sequel for free. This also works the other way, so players who pre-order or purchase A Valley Without Wind 2 will get the original for free.
