Hearts of Iron: War Stories brings a Choose You Own Adventure-style Paradox game to mobile

Plenty of console and PC games have companion apps nowadays. They’ve been getting novelizations for decades as well. But for its upcoming Hearts of Iron IV strategy game, Paradox Interactive is mixing both.

The Swedish publisher released Hearts of Iron IV: War Stories today. This “gamebook” is a companion to the grand strategy World War II game, which hits PC on June 6. Think of it like a “Choose Your Own Adventure” book in app form, linking to Paradox’s Hearts of Iron IV. Though known for its PC products, the company has released a few mobile apps before, dipping its toes into a $34.8 billion market. The first five chapters of War Stories are free, and the remainder cost $5 each.
