Götterdämmerung rebuilds Germany from scratch — the biggest and most requested tree in the game — and adds special projects that push technology all the way to nuclear weapons and rockets.
Nations and Content
Germany gets a completely rewritten focus tree, with far more alternatives to the historical path. Austria, Hungary, Belgium and the Belgian Congo get significant content of their own for the first time.
New Mechanics
Special projects are the big addition: a separate research tree for cutting-edge technology, from nuclear weapons and rockets to experimental tanks and planes well ahead of their time. The raid system lets you launch quick special operations against specific enemy targets, without needing a large-scale offensive.
Is It Worth Buying?
If your plan is to play Germany, it's the clearest purchase in the whole catalog — it's literally the rewritten focus tree of the most-played nation in the game. And special projects, being available to any country with enough technology, give a long-term goal to games that otherwise run out of objectives after winning the main war.
