Best Buy's Canadian branch and Canadian retailer Futureshop.ca have both advertised a pre-order for Dishonored with the release date set for Tuesday, September 25.
Dishonored follows a supernatural assassin driven by revenge after being wrongly accused of killing the Empress he was once sworn to protect.
It will feature a flexible combat system, enabling players to use a combination of stealth tactics and direct attacks. The outcome of each mission is said to vary depending on choices made by the player.
Announced last year, Dishonored is developed by Dark Messiah of Might & Magic team Arkane Studios, which features Deus Ex designer Harvey Smith and Half-Life 2 artist Viktor Antonov.
