Play as stealth assassin Corvo in the city of Cornwall, attempting to purge the city of corrupt politicians who murdered the Empress. Save the princess with cold dead assassinations or passively take out each enemy without shedding blood. The choice is yours... as you traverse huge castles and forts with multiple paths to your objective. Use clever skills to sneak and stealth unseen or slay guards with hungry rats or worse...

Proton handles Dishonored perfectly without any hacks or workarounds. I was able to play with all settings maxed out on my GeForce GTX 1060. I was able to play through the entire campaign and it was beautiful!
