Sometimes video games feel like call and response: One developer makes a great game, and another team (or two… or five) create their own based on that idea but with key additions or refinements — new mechanical twists, a change in scope, or a story that feels like a natural fit for the concept. In this way, Phantom Doctrine responds to the call from Firaxis’ XCOM franchise. Using the basic tactical RPG/management sim structure and workings of XCOM 2 as a foundation, from its world map and management systems to specific actions like defensive “Overwatch” posturing, developer CreativeForge reshaped it to create something new and intriguing: A Cold War-era espionage game that evokes the anxious energy that we’ve come to associate with cat-and-mouse spy stories.
