You may recognise video games as being loud, but that's not the case with stealth video games. In stealth video games, you are heavily encouraged to remain unseen and strike from the shadows. Most stealth games have combat system, so stealth is optional most of the time, but you are usually encouraged to be stealthy.
Here is a list of the Stealth Video Games that I can think of:
Metal Gear Solid
Styx Master of the Shadows/Shards of Darkness
Payday 1 & 2
Watch Dogs 1 & 2
Batman Arkham Series
Which Stealth Game in the list is the best? If there is any I missed, please let me know.
