Today saw the launch of the original Sudden Strike trilogy on Steam. It looks like this wasn't just a spontaneous decision by Kalypso Media.

Pre-orders are now live for Sudden Strike 4 (at a 15% discount) and come with a bounty of goodies for series fans. For one, orders grant an immediate free copy of the trilogy. Of course, some folks would rather see what's new than revisit the past.

Beta access is the main allure of pre-ordering Sudden Strike 4. It includes the tutorial, three single player missions and two multiplayer maps. The beta runs from now until launch on August 11.
