In most video games, the player's character is powerful enough to mow down enemies left and right. They don't have to worry about setting alarms off, or enemy reinforcements being summoned (true, there are occasionally levels where you have to be a bit careful, but those are specifically scripted).
In a Stealth-Based Game, the player's character is simply too weak to survive a head to head confrontation with his enemies most of the time. Either it's too easy to die (many of the enemies can even be Instakill Mooks), you can't carry enough ammo, enemies are either too powerful for a direct confrontation or outright invincible, or there is some other reason. Just running away from enemies like in Pac-Man isn't enough to count as a stealth-based game; you need to be actively hiding from them.
Whatever it is though, they've got to be careful, stick to the shadows, kill silently, and only when necessary. And they better hide the bodies well because someone is going to stumble over them otherwise.
The different types of stealth used can be broken up as such, though many are often hybrids.
- Line-of-sight breaking: Horizontally or vertically, stay out of view.
- Moving through shadows: Avoiding the light, creating darkness to move through.
- Hidden in plain sight: As part of the crowd or as part of the scenery.
Games in this genre may feature Optional Stealth, where playing it stealthily is encouraged but not strictly necessary.
The Ur-Example of the genre is Manbiki Shounen (1979). The Trope Maker is Metal Gear (1987), the first popular stealth-action game with over a million copies sold. And the Trope Codifier is Metal Gear Solid, which was the first 3D stealth game, having debuted in 1996 before releasing in 1998. The Metal Gear series is the Genre Popularizer, with its creator Hideo Kojima being the leading pioneer of the genre.
A sub-genre of Action-Adventure, as not only this involves active hiding, but the stealth itself is often puzzle-like, requiring knowledge of one's environment and enemy patterns for survival. For gameplay of this sort in other Video Game Genres, see Stealth-Based Mission.
Games in this genre:
- 005: An Arcade Game released by Sega in 1981, this was one of the first stealth games.
- Doomy In The Roomy
- 007: From Russia with Love zigzags in and out of the genre. It's generally easier and more efficient on the on-foot levels to play it this way, but the vehicle levels are more of a blast-everything-in-sight type deal.
- 2Dark
- Affordable Space Adventures is one where you must avoid detection from alien robots while riding a completely safe spaceship.
- Alien: Isolation: Trying to fight the Alien head-on means certain death in this game, and fighting lesser enemies such as Working Joes or hostile survivors usually costs more resources than it's worth, so much of the gameplay is spent in and out of hiding.
- Alpha Protocol: The game is designed so that the player can play it as a stealth game, a shooter or a hybrid. Note that trying to completely focus on stealth will end badly when you come up against the mandatory boss fights. At least some combat ability is necessary.
- Amnesia: The Dark Descent is, alongside Slender, the Trope Codifier of the Invincible Boogeymen horror game.
- Ape Escape allows you to sneak up on many of the monkeys you're required to catch by crawling around and staying out of sight. Stealth isn't required, and it's possible to play the game like a standard action platformer. However, if a monkey sees you, they'll try to run away so keeping yourself hidden is often ideal.

- Basingstoke: A mix of stealth and Survival Horror.
- Batman: Arkham Series - Though instead of normal stealth, it's more of a Rocket-Tag Gameplay spin on stealth the developers call 'Predator'. If the enemies get the drop on you, it's bad news for you, but if you get the drop on them, it's bad news for them.
- BioShock Infinite: Burial at Sea - Episode 2 - In this DLC, you play as Elizabeth, who takes hits harder than Booker, and ammo and health are very scarce, leading to an increased emphasis on stealth.
- Boiling Point: Road to Hell is one of the first open-world first person shooters (predating Far Cry 2 by a few years), but the scarcity/expense of resources and quickness in which you die both heavily encourage stealth, especially in the early parts of the game.
- The Blackout Club - A cooperative multiplayer survival horror game that is centered around sneaking around to do missions.
- Bonanza Bros. - a mix of Stealth and Run & Gun Side-Scrolling Shooter elements.
- Bramble: The Mountain King
- Budget Cuts - One of the first virtual reality stealth games, if not the first notable one.

- The Burgle Cats
- Call of Cthulhu: Dark Corners of the Earth doesn't give you any weapons for about the first 1/3rd of the game, mandating stealth against your pursuers. Even after acquiring firearms, scarce health and ammo heavily encourage a stealthy playstyle.

- Chameleon
- The Church in the Darkness
- City Shrouded in Shadow
- The Classroom Trilogy, Flash games where the objective is to cheat on tests without getting caught.
- The Clue!
- Cold War
- Cold Waters: You play as a US Submarine in either 1964 or 1986 and your job is to sink as many Soviet ships and submarines as possible. If they detect you, expect numerous inbound torpedoes in short order.
- Commandos: A game series where in each game a group of soldiers are controlled from an aerial view. Each soldier is extremely fragile, and the maps are filled to the brim with enemies, making clever use of each soldier's special abilities to avoid detection central to the gameplay. Most stealth is in the form of line-of-sight breaking.
- Conflict Series: The games have the option for players to sneak up on enemies and take them out while they're not detected.
- CounterSpy: Though fighting your enemies head on is an option, the game discourages this unless the room is full of enemies. Being seen will simply raise the overarching DEFCON, which will lead to a Timed Mission, which will lead to a Game Over.
- Courage's Curse
- Covert Action: Drawing attention to yourself (e.g. visiting lounges for hints within the city) will cause hitmen to chase after you on the road or an ambush, although this will give a location of one of the safehouses. In a building, getting spotted will raise the alarm and cause guards to converge on your location although you can mitigate it by getting a disguise.
- Crysis, a hybrid of this and First-Person Shooter.
- Dark: A vampire stealth game.
- Dave.EXE
- Death to Spies: A World War II game where you need to infiltrate enemy locations to complete tasks. Stealth is handled by wearing enemy uniforms, and trying to complete objectives. The stealth portion is difficult as there's bound to be at least one person specifically watching over the only route to the objective, who is likewise being watched. The ideal rank is based on factors concerning combat (using non-noisy weapons), aggression (kill as few as possible), noise (minimize alarms or spread of information), professionalism (using non-cold weapons, or mis-using hot-weapons depending on uniform), and precision (accuracy; only a factor for professionalism).
- Data Jack is about playing as a cyberpunk hacker, combat is discouraged by healing costing money and dangerous foes.
- Deceit: A game where two Infected players have to drink blood without being spotted by the other 4 players who are the Innocent players, as well as potentially sabotage objectives by the innocents that would allows them to acquire useful gear. The innocent players do not know who is infected, hence why the Infected stealthily accomplishing their objectives is paramount lest the infected being voted out. Also, during the night, Infected can transform, thought it is recommended to only do so while out of the line of sight of other players to avoid being identified by your soon to be victim who could communicate their identity before they kill him.
- Deceive Inc.
- Desperados: A Wild West clone of Commandos; the player views the game from above, and must carefully navigate a group of outlaws, each with their own special abilities, through hostile territory without drawing too much notice.
- Desperate Escape
- Deus Ex franchise: Every game in the franchise can be played as a full-out stealth game, as a shooter, or a hybrid. The games encourage at least some stealth, however. The games in this franchise include:
- Deus Ex
- Deus Ex: Invisible War
- Deus Ex: Human Revolution
- Deus Ex: Mankind Divided
- 2027: All but a necessity, due to the high weapon damage of the game.
- The Nameless Mod
- Devillish Series a Flash game series where the objective is controlling the titular character and doing various mischiefs without getting caught.

Heavily inspired by Deus Ex, in that exploration is possible and multiple paths are usually available through a level. Sneaking is done by breaking line-of-sight and staying in shadows.
- Disney's Hide & Sneak
- Dynamite Jack
- ECHO

- Entry Point (Roblox): There are benefits for playing stealthy, and there also exists a gamepass that includes 3 missions that must be cleared in stealth.
- Far Cry, a hybrid of this and First-Person Shooter. More so than its Spiritual Successor, Crysis, due to the scarcity of health and armor and absence of Regenerating Health.
- Fear Effect doesn't force you to be stealthy, but it will almost certainly be preferable to attempting to use the control system in a real firefight. There are also a handful of missions where guns are not an option, and the emphasis is timing your movements to evade detection.
- Five Nights at Freddy's: Security Breach: In contrast to other installments in the franchise, Security Breach is free-roam with many of the mechanics centered around moving around the Pizzaplex without drawing attention to yourself, such as hiding inside a friendly animatronic, using various ways of stunning and distracting enemies, and using the series' trademark cameras, this time accessible on a Gadget Watch, to plan out a path in advance.
- Geneticognito
- Get Even (2017): Partly crosses with Psychological Thriller and First-Person Shooter. Combat is viable but heavily negatively affects your Karma Meter.

- Gorky Zero
- Gunpoint: A future-noir themed 2D puzzle-platform game involving rewiring buildings and evading guards.
- Headhunter: An action adventure game that takes many cues from Metal Gear Solid. While your characters can defend themselves if they're caught by enemies, it's more preferable to kill them undetected. Some of the first game's L.E.I.L.A. tests require you to reach the end of the level without being seen.
- Hello Neighbor: A stealth horror game where you avoid your neighbor while trying to get inside his basement.
- The Hidden: Source, a Half Life multiplayer mod.
- El Hijo - A Wild West Tale
- Hitman: Here the emphasis is strictly on the use of disguises and not appearing suspicious; as noted in the description, you're generally operating in a crowded area until you reach your target. Entries in the franchise include:
- World of Assassination Trilogy:
- Invisible, Inc.: You can take out guards by killing them or knocking them unconscious, depending on your equipment, but it's usually better to avoid it unless necessary. Guards are fitted with heartrate monitors that increase the security level if they die, and KO'd guards will wake up in a few turns and start searching for you.
- It Steals is a horror game where you are pursued around a maze by several different Eldritch Abominations. Stealth is essential to keep the monsters from detecting you, as you can only drive them off a limited number of times. Some are also faster than you are, so you aren't even able to run away.
- Judgment
- K Hawk Survival Instinct
- The Last of Us
- Legacy of Kain has occasional elements (in Soul Reaver and its sequel, you can get a one-hit kill if you catch an enemy unawares), but it's most prominent in Blood Omen 2, which lets Kain turn invisible when he's in mist, and has a whole stealth kill system associated with it.
- In Little Nightmares and Little Nightmares II, you play as small children in a giant-scaled world with (almost) no way of fighting back against the game's many monstrous enemies. Consequently, much of the games are spent observing their patterns and powers and hiding from them or running to places where you can hide.

- Lugaru

The first game has a kidnapped death row inmate promised freedom in exchange for playing the lead role in a snuff film director's latest movie; the second is about a pair of insane asylum escapees trying to recover their memories of a secret mind control project and their roles in it.
- Quantum Replica is this combined with Adventure and Shooter elements.
- The Mark of Kri and Rise of the Kasai are a mix of this and Hack and Slash. The games don't force you to be stealthy, and you're tough enough to fight your way through, but stealth is usually the preferred choice and generally makes things easier.
- The Mark, an espionage-themed FPS.
- Mark of the Ninja: A 2D platformer where the player character is a ninja. Stealth comes from breaking line-of-sight, staying in shadows and making as little noise as possible.

- Messiah: Action-Adventure where the player character, a small cherub, possesses various people to blend in. The stealth mechanics primarily rely on the player hiding in plain sight, as a result, although on higher difficulties, targets can only be possessed when their backs are turned, necessitating line-of-sight breaking as well.
