The 2012 game "Dishonored" tried to incorporate stealth elements that were influenced by ', such as the importance of lighting and shadows. The developers later abandoned that system citing realism as a factor. The game instead relies on a system of "occlusion-based" stealth, using the vision cones of the enemies, obstacles, and special abilities which determines whether or not the character is visible. Additionally, while other games had implemented such systems, "Dishonored" was recognized for having a forgiving stealth system compared with "Splinter Cell", in that if detected, the player had several options available to either attack those enemies that detected them, distract them, or flee and outrun them by using parkour, rather than immediately reaching a "game over". Forbes called "Dishonored" one of the best stealth games of 2012, along with ' and "Mark of the Ninja". "Mark of the Ninja" puts a twist on the stealth genre in that it is a 2D side-scroller. This posed some unique factors, such as the lack of corners for the character to hide behind, and the visibility presented in a side-scroller; the developers overcame this by adding 'fog' that prevents the player from seeing things that the character can not see, visually representing enemy line-of-sight and even visualizing the noise made by the character, including how far that noise travels. After the completion of the game, the player has access to a harder difficulty called "New Game Plus", which further decreases visibility by adding fog behind the player and removes noise visualizations and enemy line of sight indicators.
