Dishonored - Stealth Answers
The Bethblog has posted more developer responses in their ongoing Dishonored community Q&A series. As previously, it's fairly short, so here's the whole thing:
Q: In the Dishonored gameplay videos Corvo seems capable of hiding from enemies who are very close, even when they’re looking in his direction. Is he cloaked or are cheats enabled for the demos? (from StealthAssassin)
A: In Dishonored, stealth is occlusion-based, meaning it’s mostly based on enemy view cone and hiding behind objects or architecture. (At a significant distance, lighting is also a factor.) What you might be describing is the Lean feature. If Corvo is hidden behind something, he can lean out to see ahead, eavesdrop, and observe the situation. As long as Corvo’s body is hidden, enemies up ahead will not see him. Dishonored also allows players to peep through keyholes, and the game has a Dark Vision power that can be obtained. Dark Vision displays enemies and their view cones through walls, and it features an abstract representation of the sounds the player makes.
Q: How will the save system work? Does the game have checkpoints or can I save everywhere I want? (Sebastien H.)
A: Both. You can’t save during combat, that is the only constraint.
Q: How is gameplay varied based on the difficulty level you choose? (Cory G.)
A: (courtesy of Game Designer/Associate Producer, Dinga Bakaba): Dishonored features four levels of difficulty, ranging from a casual experience to a demanding challenge. The main factors affected by difficulty are enemy perception, damage and responsiveness, as well as health and mana potion potency. Easy also causes part of your health to regenerate over time.
