The cliché of delivering an "open-world" game is something that developers have been touting since the last generation of consoles. Giving players a massive sandbox to roam around in is certainly a fad of today's market, but that alone isn't enough to satiate the appetites of those who have been playing the Grand Theft Auto series over the last several years. Mirror's Edge, from DICE the creators of the celebrated Battlefield series, presents players with a familiar setting. There's a giant city, you can go anywhere, leaping your way up and across the face of buildings, scaffolds, and generally anywhere that you can see. The twist? It's all delivered through one of the most active first-person displays that we've ever seen.
