“When we looked at what we wanted to do with the sequel, we had all these very, very ambitious goals,” said Solomon. On his must-have list were high-fidelity characters and environments, better-looking destruction, physically based rendering, and the crown jewel he’d wanted to get into Enemy Unknown but couldn’t: procedurally generated maps. “To do that, we had to use all of our studio expertise … and our expertise here is PC. That's our home, and that's where we're really comfortable.”

Focusing all of Firaxis’ efforts on the PC made logistical sense to DeAngelis, too. “Internally, with a relatively small team for the size of the game that we are, to be able to say we can focus on our platform that the studio has a pedigree for, and that X-COM: UFO Defense has a pedigree for, as PC-only... it just made a lot of sense, and that's how we wanted to dedicate our time.” XCOM 2 runs on a heavily modified version of Unreal Engine 3.5 (Firaxis’ customizations are too extensive to easily move to Unreal 4), which in some ways has been rewritten to the point of being “unrecognizable,” and it’s much simpler to make that work on one platform than three or more at once.

“We talk about ‘What is the experience like on PC? What does the mouse feel like in this experience?’” The most obvious change resulting from those conversations is how the team is optimizing the interface to be mouse-and-keyboard friendly, moving UI elements and grouping them logically so that buttons we’re likely to press one after the other aren’t placed on opposite sides of the screen. “It will certainly be recognizable, but there isn't one UI widget that's the same,” said Solomon. We’ll also see more tactical information (such as detailed explanations of why your chance to hit is increased or decreased) displayed on the tactical interface, since Firaxis can now count on players sitting closer to their PC monitors and being able to read smaller text. And though Firaxis plans to add it in the future, the current plan is to launch without gamepad support.

Of course, the one thing that a console version of XCOM 2 wouldn’t be able to handle at all is modding, which Solomon and DeAngelis consider to be one of it’s biggest features and key to offering the kind of long-term replayablity and value people have come to expect from the makers of Sid Meier’s Civilization. We’ll have more on how Firaxis is embracing modders in XCOM 2 next week.
