Today, Paradox Interactive's Hearts of Iron IV: Together for Victory — the World War II grand strategy’s first expansion — releases at the price point of $14.99 USD onto PC. And to celebrate, the developer/publisher has released a new launch trailer to get you hyped about new autonomy systems and such.

As previously reported, Together for Victory sets the models for many future add-ons (and Paradox game's always have a huge slab of post-launch content for its games), and brings new gameplay options to nations outside the great powers. Perhaps most notably, the update includes a new autonomy system. Now subject states are not merely puppets, but can have a range of action, including working their way to independence. It also notably adds tech sharing among allies. Obviously, there's bunch more coming with the expansion, and you can read about via the link at the start of the paragraph.

Meanwhile, you can check out the new launch trailer which mostly just summarizes and showcases what the expansion brings:
