Released by Looking Glass Studios in 1998, and powered by their own in-house developed Dark Engine, Thief: The Dark Project was in many ways a revolutionary title. Although it utilized a first person perspective, it was not an action-oriented shooter like almost all other first person games. Instead, the emphasis was on stealth: The character was not particularly agile nor a skilled fighter, and much of the gameplay involved using shadows to avoid enemies. However, for those who desire action, there are weapons available that allow direct confrontation. A skilled player can often break cover and go head-to-head with the enemies. An even more skilled player can stay in cover and never let the enemies know that he was there. The game's original gameplay quickly developed a cult following.
