One of the many reasons why 1998 was such a groundbreaking year for gaming is Thief: The Dark Project, a game that helped invent what's now commonly referred to as the stealth action genre. Though two other noteworthy stealth action games were released that same year--Metal Gear Solid and Tenchu: Stealth Assassins--Thief's brand of stealth was the most convincing, and it went on to become the most influential. The original developer of Thief and its similar sequel is unfortunately no longer in business, but Eidos and Ion Storm thankfully snatched up the rights and have finally delivered a new chapter in the series that's suitable for longtime Thief fans and newcomers alike. Like its predecessors, the new Thief: Deadly Shadows features a memorable protagonist, a great setting, and some very interesting missions. It also happens to suffer from a variety of miscellaneous, minor flaws. These are unfortunate, since Thief: Deadly Shadows is great game, for the most part.
At its core, Deadly Shadows sticks very closely to the formula of the older Thief games, which are first-person perspective action adventures in which you must carry out a series of high-risk, high-reward missions as Garrett, a self-serving master thief living in a cold, surreal, medieval world. As in previous Thief games, the gameplay in Deadly Shadows primarily revolves around having to retrieve a bunch of special trinkets (and other riches) from assorted heavily guarded establishments--and doing so by hiding in shadows, waiting for unsuspecting guards to turn their backs, and then blackjacking them so that they remain unconscious for the remainder of the mission. You'll have a wide variety of other gadgets to help you, including lock picks, water arrows for dousing torches and other firelight, flashbombs for temporarily blinding opponents, and more. There's always a compass onscreen to help you navigate the sometimes mazelike environments, and you'll also be paying close attention to the onscreen "light gem," which changes color depending on how well-concealed you are. This interface feature has always worked great in the Thief series.
You'll be treated to an intriguing story, which is narrated by an even more intriguing protagonist, whose particular brand of cynicism isn't nearly as unwelcome as cynicism tends to be. The story gradually and surprisingly unfolds during the course of what's a decidedly lengthy single-player adventure. Due to the open-ended nature of the game and its four available difficulty settings, average playing time should vary quite a bit from one player to the next. However, it's safe to say you're not going to get through this one in a weekend, unless all you did was play.
