The game is played from a first-person perspective and allows the player to undertake a series of assassination missions in a variety of ways, with an emphasis on player choice. Missions can be completed through stealth, combat, or a combination of both. Exploring each level opens new paths and alternatives for accomplishing mission goals, and it is possible to complete all missions, eliminating all of Corvo’s targets, in a non-lethal manner. The story and missions are changed in response to the player’s violent actions or lack thereof. Magical abilities and equipment are designed to be combined to create new and varied effects.
