Eldritch is a 2013 indie videogame developed by Minor Key Games for Windows (Mac and Linux ports are forthcoming). Its gameplay is a combination of First-Person Shooter and Roguelike (with some Platform Game and Stealth-Based Game elements), using Minecraft-like graphics.It is set in the Cthulhu Mythos universe and requires the player character, an amnesiac librarian, to explore randomly generated levels in strange worlds in order to retrieve three souls, which are needed to open a library door leading to the final level. The world is separated in several parts:
The Library (hub)
Lost city of R'lyeh
The Endless Library (unlocked in the Library with the souls found in each of the other worlds)
All The Worlds Are A Stage: The Endless Library contains every type of monsters and traps encountered in the previous three worlds.
Amnesiac Hero: The player character is one of the people who made the ritual which sealed the Old Ones in the Library, but the ritual left them amnesiac, and they remain there as a warden. It is implied that it happens again if the game is won without gaining the Golden Ending.
Artificial Stupidity: The enemies are damaged by the traps but don't try to avoid them. It isn't uncommon to enter a previously unexplored area, and then find a corpse stuck in the middle of a field of spikes.
Benevolent Architecture: For Lovecraftian Eldritch Locations, the game levels are surprisingly easy for human beings to explore, considering the size of doors, the ceiling heights, the ladders, or the possibility to climb some wall blocks to reach another floor.
Backstab: Any unaware enemy attacked by the player takes additional damage.
Character Customization: The player's avatar can be freely edited in-game by swapping out heads and bodies. Oddly, the game doesn't separate the female ones from the male ones, allowing you to play someone with a beard and breasts.
Choice of Two Weapons: The player character can exactly carry two weapons (any combination of throwing one use weapon, mêlée weapon, ranged weapon, or just unarmed punches) and one magical spell on the same time.
Double Jump: The Lift spell is both an upgraded jump (when used on the ground) and this trope (when used in the air).
Everything Fades: Enemy corpses stay on the ground until they have been looted by the player. They disappear a few seconds later and the enemy respawns some time after.
Excuse Plot: You are an amnesiac adventurer exploring three randomly-generated Eldritch Locations in order to find three alien souls to unlock the big door toward the last level.
Extreme Omnivore: The Tinning Kit item allows the player to eat the dead enemies' bodies to regain health. I'm a Humanitarian is averted because they won't touch the dead cultists. Apparently giant floating eyeballs and lizardmen are okay.
Faceless Eye: One of the enemies is a giant floating eye that throws fireballs.
Fictional Document: Most of the game's plot is revealed in the scattered pages of The History of the Library and the Explorer's Journal.
Hub Level: The library level, which is devoid of enemies and holds doors to other levels (including the final one, a sealed part of the library).
Hyperactive Metabolism: The player is required to eat fruit, meat, and drink water to regain health; water heals more than food and also serves as the game's HeartContainers. The Tinning Kit item allows to eat dead enemies in exchange for 20 artifacts.
Grievous Bottley Harm: Each bottle is a one-use ranged weapon. They're the first weapon found ingame: there are four of them in the starting area.
Another weapon is a rock which can be thrown and retrieved. If used too near to the target, its bounce can kill the player character.
In the Hood: The cultist enemies, which wear hooded robes completely hiding their faces save for the glowing eyes.
Interchangeable Antimatter Keys: Played straight. Any locked door can be opened by any of the generic green keys lying in the dungeon (or bought from shops), which immediately disappear after unlocking said door.
Item Farming: As enemies respawn and always carry a few artifacts, bullets, or keys, the safest way to gather enough of them is to randomly wander in the first and second levels (which only harbour the weakest enemies) to amass enough of this.
The Juggernaut: The Shoggoths. They only have an average speed, but are unkillable, can open doors, and can climb stairs. They are only stopped by un-jumpable walls, ladders, and one-square-wide tunnels.
Killed Off for Real: As with any other roguelike, when the player character dies, the game must be restarted from scratch (inside new Randomly Generated Levels). The only things remaining from previous player characters are the amount of artifacts stored in the bank chest and the worlds already unlocked (which isn't very useful, as the souls themselves must be retrieved again).
Carrying a Medical Kit when dying revives the player character in exchange of 50 artifacts.
Living Statue: The Creepy Statues are statue-shaped monsters which seem to be still but can teleport behind the player (if still in their field of view) and attack him/her.
Lovecraft Country: One of The History of the Library books explicitly stated that the Library is built in New England.
Lovecraft Lite: The player character explores Lovecraftian places full of monsters... which can be killed by shooting them, stabbing them, or throwing rocks at them. There's no Sanity Meter or unwinnable boss fights against unkillable abominations. Possibly subverted in the bad ending, which states that some Old Ones managed to escape the boundaries of the Library and are wreaking havoc.
Luck-Based Mission: In the shops, the only items which can be bought are those displayed on the counters. The selection is always random.
Magical Library: The starting area is a big deserted library featuring three interactive "strange books" (which emit coloured rays). Activating one teleports the player character into a strange place. The Library is actually a prison for the Old Ones.
The Maze: Asymmetric example. Without including the Hub Level, the game is divided in four worlds, each of them having three levels separated by a hatch door. Each level is actually a three-dimensional maze of stairs, ladders, corridors, and doors (sometimes locked) occupying three floors.
Downer Ending: The player character performs the Ritual of Bending but didn't manage to light all three candles. Some of the Old Ones are free to roam the Earth and the player character ends stuck as the library guardian.
Bittersweet Ending: The player character performs the Ritual of Bending after lighting the three candles, but didn't find the three special items - see below. The Old Ones remain trapped within the library, but the player character ends stuck as the library guardian.
Golden Ending: This one requires to find three items in the shadow worlds of previous levels - the Holy Symbol, Sandals, and Consecration Kit -, which are totally useless and take up an inventory slot. If the player characters carries all three of them while successfully performing the Ritual of Bending, the Old Ones will be trapped but the player character won't.
New Game+: Provides a harder difficulty after beating the regular game. It actually figures into the plot: if the player managed to perform the Ritual of Binding successfully but without the three items necessary for the Golden Ending, he is still trapped in the Library.
Nice Job Breaking It, Hero: The amnesiac hero - which has been left in the Library as its guardian - explores the place and breaches the Old Ones prison. If at the end the Ritual of Bending isn't correctly performed, some of them manage to get loose and wreak havoc on the Earth.
Non Standard Skill Learning: Spells are learned by praying in front of a statue. Each type of statue grants a specific spell; only one spell can be learned at the same time and praying replaces the current spell with a new one.
Noodle People: The humanoid characters (including the player character) all have an exaggeratedly large head on top of a skinny body.
Perma Stubble: A couple of the male player character heads include this.
Practical Currency: The shop currency is Artifacts, blue engraved circles which are also the (non-regenerating) mana of the game, which serves to power spells and fuel some items' abilities.
Purely Aesthetic Gender: The player character gender is selected in the library level (after the game starts) by using a mirror to customize the player character's appearance. The PC's gender and appearance don't have any effect on the gameplay itself.
Razor Floss: The Tripwire Gun is a crossbow which fires a bolt linked to a wire. While directly shooting an enemy inflicts a few points of damage, the main role of this weapon is to shoot wires to set such traps. Preexisting wire traps can be found in the game from the second world on.
Sealed Evil in a Can: The Library is actually a prison for the Old Ones. Failing to perform the Ritual of Bending sets some of them free.
Sequence Breaking: Once the later worlds are unlocked at the start of the game, it's often most efficient to take a quick tour of the topmost part of Dagon to farm for items but retrieve its soul last.
Set a Mook to Kill a Mook: There is an automatic infighting feature between monsters of different kinds. The game also includes a spell which briefly turns a monster into the player character's ally.
Shoplift and Die: In the shops, stealing an item or lighting one of the dynamites on display will anger the merchant, who will attack the player character. He is a lot stronger than the identical looking monsters of the area, but he isn't invincible.
Spikes Of Doom: On the floor, on the walls, and sometimes under collapsing ground tiles. Hitting them drops your health by two hearts. Thankfully, the enemies aren't immune. The Mountains of Madness DLC has a ceiling-based variant in the form of falling icicles.
Stealth-Based Mission: Playing the game like this is quite effective, thank to a couple of features. Enemies only attack what they can already see, Backstab attacks inflict more damage, the Stealth Boots item allows you to walk and run without making any noise, the Cloak spell makes the player character invisible but still noisy (unless you have the Stealth Boots), the Tripwire Gun allows to set traps, and the player can throw bottles to distract enemies.
In addition, you can safely lean around corners (which can help in combat, but is invaluable for stealth), and crouch-movement is reasonably quick and almost completely silent.
