Arcen Games has sent word today that A Valley Without Wind has entered beta for those that pre-order the game. Along with that, Arcen is running a promotion right now - if you pre-order the game, you can do so at a 50% discount making the price just $10.
If you want to see what A Valley Without Wind is all about, you can download the demo which is now also available. The only limitation of the demo is that civilizations in the game can not go above level 6. If you want you can convert your demo into a fully featured beta by then purchasing it. Arcen also wanted to let users know that there is no DRM in the game - only a simple license key.
Sadly the beta and the demo right now does not feature co-op multiplayer, though you can expect it to be added as time goes on. Right now Arcen expects A Valley Without Wind to launch in early 2012.
