Thief II: The Metal Age
Thief II is a stealth game that takes place from a first-person perspective in a three-dimensional (3D) graphical environment. The player seeks to complete mission objectives and to evade the notice of opponents such as guards.  The player must minimize the visibility and audibility of the player character, Garrett, to escape detection. Players try to avoid lit areas and loud flooring in favor of shadows and quiet flooring. A light monitor on the heads-up display (HUD) indicates the player character's visibility. While it is possible for the player character to engage in direct combat, he is easily defeated.
