''Ken's Labyrinth'' is a first-person shooter DOS game, released in 1993 by Creator/EpicGames (then called Epic [=MegaGames=]). It was mostly coded by Ken Silverman, who went on to design the Build engine that was used for rendering a first-person viewpoint in Creator/ApogeeSoftware's ''VideoGame/DukeNukem3D''. It consists of three episodes, the first of which was released as {{shareware}}.

Here's what's going on, plot-wise. The Zogar [[DepartmentOfRedundancyDepartment Imperial Empire]] led by the [[AuthorAvatar infinitely evil (and ugly) Ken]] takes people from various worlds and puts them in their danger-filled labyrinth [[ItAmusedMe just for their own entertainment.]] If that person doesn't make it out of the labyrinth alive, their home planet becomes coal for the Zogarians' jelly-making stoves. By the way, [[NintendoHard nobody has pulled it off.]]

The Zogarians have kidnapped your dog Sparky. They interrogated him, and found out that dogs are some of the smartest creatures in the universe. So now, the Zogarians are too afraid he'll solve the labyrinth, and they're making ''you'' do the labyrinth instead. You also need to rescue Sparky, while you're at it. Remember, if you don't pull it off, Earth becomes jelly stove fuel. No pressure.

The game has been released as {{Freeware}} by Silverman himself.
!!This VideoGame contains examples of:
* AuthorAvatar: Ken is based off the coder Ken Silverman.
* BigBad: Ken.
* BottomlessPits: And they come in two flavors, too!
** The first is basically your standard garden-variety hole in the ground. The second kind has red eyes and moves around. Either way, move over one and you die.
** Enemies can fall down the permanent holes (yes, [[CrowningMomentofFunny the living holes can, too]]). They won't, however, go down the moving holes.
* BossRush: The final stage has you fighting the bosses of the first two episodes before taking on [[BigBad Ken]] himself.
* ContinueYourMissionDammit: Because there is a timer counting up for each level, it may seem like you're dealing with a TimedMission, ''HOWEVER,'' the only thing that the timer affects is your [[ScoringPoints score for the level]] (a 10-point penalty for every second you take).
* EscortMission: The entirety of episode 2. The game will ''not'' let you move on to the next level unless Sparky is with you. (In fact, it'll even say, "Where's your dog?" if you try to leave the level without him.) This can lead to an {{Unwinnable}} situation, because Sparky can fall down permanent holes.
* FeaturelessProtagonist: You never see the protagonist's face, as they are supposed to represent the player.
* HyperactiveMetabolism / HealThyself: Eat an apple, and you get about a twelfth of your health back. A meal is good for about a sixth of your health, and a first-aid kit gives you back about a third of your health.
** Starting in Episode 2, there are [[MookMaker beehives that spawn bees.]] You can shoot the beehive and destroy it, then pick up the honey it drops for about as much health as an apple.
* IdiosyncraticDifficultyLevels: They are named "Don't Touch Me" and "OUCH!" and subtitled "Easy" and "Hard," respectively. On easy mode, enemies generally will not use melee attacks, while on hard mode, [[CollisionDamage they will ram into you, thus causing damage.]] Therefore, the idiosyncratic level names actually make sense.
* InvincibilityPowerUp: The gray cloaks, which will protect you against everything that is not a hole.
** Also, the green potions let you reflect projectile attacks back at the enemy, and the blue cloaks let you [[OneHitKill kill enemies just by touching them.]] (Problem with the latter, if you're interested in ScoringPoints, you don't get any points if you blue-cloak them.)
* LuckBasedMission: There are slot machines at various points in the game. You can play the slots using coins you find around the labyrinth. The payouts go up to 200 coins, but you're far more likely to lose.
* NoFairCheating: Using cheats will literally bar you from completing each episode and seeing the endings.
* OneUp: A blue disk thing with a man's face on it. There are a total of 8 in the entire game.
* QuadDamage: The purple potion both lets your shots go through walls and doubles the damage you do to enemies with your shots. As a nice bonus, it also halves damage that enemy shots do to you.
** Also, the missile weapon does twice the damage compared to the jelly gun or bouncy bullets.
* SaveThePrincess: Except that the "princess" here is actually a male dog.
* ScoringPoints: And that's all they're good for - the high score board for each level. No, points don't carry over between levels.
* TeleportSpam: [[FinalBoss Ken]] does this when he's close to dying.
