Bethesda's Dishonored has arrived with considerable hype surrounding it, which can often be an indication of a game with shortcomings.
Gladly, this is far from the truth in this instance.
You are Corvo Attano, the once-trusted bodyguard of the Empress. Framed for her murder and empowered with supernatural abilities, you
become an assassin to seek revenge on those who ruined your life.
Dishonored's gameplay is firmly entrenched in stealth tactics. You can certainly choose to run and gun, causing as much carnage as you like, but you will need to be prepared for the consequences.
Most missions can be completed without harming anyone (apart from targeted assassinations) using a mixture of stealth and supernatural skills.
