Dark Sector has been a long time in the making; it was one of the first videos shown for then-upcoming PlayStation 3 and Xbox 360 upwards of four years ago. We asked the development team about this at the Game Developers Conference and were told that the principal work of the game has only been going on for two years or so, and that doesn't sound quite as protracted as it has been made out to be in the press. In fact, when you consider that Digital Extremes has built its own engine for the game, and that it runs effortlessly on both the PS3 and 360, the long development time seems very well spent. How good is this engine? Many people seeing the game in action assumed it was running on Unreal Engine 3. No tearing, no slowdown—just smooth indoor and outdoor scenes. Not a small feat.
