Generals!

_**Thunder At Our Gates**_ is officially out now! Jump into the thick of the South-East Asian rainforests and battle your way through to victory. Or if you prefer a more grainy environment, stick to the Australian continent and send your expeditionaries to hold Tobruk like a real desert rat.

This is our first **Theater Pack**, a smaller DLC which includes both country content as well as gameplay features. With it you get new content for Australia, Siam, and Indonesia as well as the inclusion of the new Army HQ feature and Ship Captains (and regimental support in the free patch!).

We hope to see you out there protecting the Pacific or uniting it under your banner!
