Eldritch is a randomly generated first person action adventure game and contains a number of places to explore. The Explorer enters these places via several Strange Books located in the Library.
SPOILER ALERT: for those players who want to experience a first-time Eldritch run with fear of the unknown intact be aware this section reveals quite a few specifics, especially as to game endings and the expansion levels. Read further at your own risk!
The LibraryEditThis is the hub of Eldritch. It is filled with books that offer clues as to the nature of the game world. There are no Denizens in the Library's three floors, nor is every square is accessible; the second and top floors can be closed off completely.
There are three glowing Strange Books which allow you to access the three main worlds of the game and a Chest in which you can store and access Artifacts which act as the game's form of currency. The "Mountains of Madness" expansion adds a fourth book leading to the eponymous Antarctic mountains. A final fifth book leads to the Asylum challenge level.
The Mirror allows players to customize their appearance, although they will not be visible at any other point in the game. Desk lamps may be shut on and off. Fruit will grow on saplings at random throughout the Library.
The Library's layout is randomly generated outside of the starting areas and features. In the current game build the Library is locked to a single layout at the start of a run, but it is possible to reveal other squares using the Pickaxe or Revolver/Destruction Amulet combo, sometimes uncovering more rooms of tables, lamps, and most importantly Fruit.
DagonEditThis is the first world that the Explorer can access. A book (with an accompanying Compass item, a benefit missing in New Game+) can be found in the beginning area, which tells about this world, a temple to the water god Dagon.
Denizens that may be encountered in Dagon include Deep Ones, Bugs, Worms, Dagon Cultists, and in later levels, Flying Eyeballs and Shoggoths.
Hazards that may be encountered are spikes, harmless when walking through them, but deal 2 points of damage if running through or jumping into them.
This world contains a lot of loot which will be useful when exploring later worlds. Full Fountains also seem slightly more frequent than in other worlds. It is best to start out in Dagon even after all the books are unlocked because the player can easily stock up on inventory items, which will be very much needed in the two other worlds.
This is the second world of Eldritch and considered to be the most difficult of the three worlds due to how dangerous the Denizens are: Mummies that rise again when killed, Lizardmen that jump, dodge, and spit, Fire Bugs that shoot fireballs, and Lizardmen Statues that attack when not observed and are invulnerable to conventional damage.
Denizens that may be encountered in Nyarlathotep include Lizardmen, Lizardmen Statues, Fire Bugs, Mummies, and Nyarlathotep Cultists.
Hazards that may be encountered are tripwire traps that deal 1 point of damage (and may be disarmed, giving 1 bullet), unstable floors that collapse when stepped on or jumped into from beneath, and spikes.
The Tripwire Gun can be found in Nyarlathotep, as loot or in stores.
The third area of the game, R'lyeh, is an amalgam of a sunken ship and temple ruin flush with plant life and fleshy growths.
Denizens that may be encountered in R'lyeh include the sleepy Star Spawn, Flying Polyps, R'lyeh Cultists, and harmless Deep Ones. The creatures here are resilient with many hit points, though they lack the "tricks" of Nyarlothotep's Denizens, making them easier to handle.
Hazards are plenty in R'lyeh. Notable hazards include "barnacle" eyes on floors and walls that explode in poisonous gas when the Explorer is near, spike walls, floor spikes, and plenty of tripwires.
The Endless LibraryEdit
The final portion of the game takes place where you begin. To reach the Endless Library stage one must collect all three Souls from each of the three Worlds and place each Soul on the three pedestals opposite the Library Door. The door will open and the Explorer can enter the second part of the Library.
Denizens that may be encountered in the Library include any found in Dagon, Nyarlathotep, and R'lyeh.
Located in each of the three levels of the Library are candles. Candles are most often located on the second floor of each level and only accessible from the top floor without other tools of ingress. Lighting all three Candles before reading from the Ritual of Binding book found on top of the final floor gives the Explorer the Good Ending. Failing to light all the Candles leads to the Bad Ending.
There are no Hazards in the Library other than menacing heights.
This world can be found within Dagon, Nyarlathotep, and R'lyeh by discovering a secret room containing a Dusty Book. This room is only found on on the second floor of the second level of each World and can be difficult to reach without mining its walls or thorough exploration.
Each Shadow World is two map squares in size and contains a number of Artifacts. They also house a unique piece of equipment, none of which grant the player any special power. Instead these items are needed in order to achieve the Great Ending:
- Holy Symbol (Dagon) - Gear
- Sandals (Nyarlathotep) - Boot
- Consecration Kit (R'lyeh) - Kit
Where they are found appears to be locked to each World. These items are referred to in the Librarian's journal entries, which may be found in the Library.
Mountains of MadnessEdit
This expansion adds a new level in the Antarctic mountains based on Lovecraft's novel At the Mountains of Madness. The level is initially predominated by ice and snow but slowly changes over ten floors into a massive mushroom cavern as the Explorer descends. Later floors are incredibly dark, making safe navigation a challenge. Several new Items, Denizens, and Hazards are introduced in this expansion:
- Penguins, Elder Things, and Mi-gos are some of the dangerous new Denizens encountered in this world.
- New weapons and tools include a Pickaxe that digs through blocks, a Hatchet that chops down wooden doors, and a Grappling Hook that shoots a climbable rope anywhere.
- Icicles scattered all over ceilings are a new hazard that will fall down upon the player as soon as they walk underneath them, doing 1 damage in the process.
- Health is extremely rare, getting progressively rarer the farther one descends. The Explorer must rely on scarce Fire Pits that restore 1 hit point when interacted with. These pits may be rekindled at the cost of 10 Artifacts with the new Campfire Kit.
- Green Vases may be packed with Piles of Artifacts...or contain biting Bugs instead! Break one open and find out!
- There's a piece of Soapstone near the mountain entrance, but it seems to do nothing...
The Mountains are more challenging than the original three worlds due to scarcity of resources, abundance of dangerous Denizens, and the length of the world itself. If you are collecting all three Soul Orbs, this world can be passed over and is not mandatory.
To leave this world, the Explorer must descend all ten levels to retrieve a pair of Plane Keys, located on an altar surrounded by Cultists, then ascend all the way back to the surface level. When the keys are taken, a black cloud first seen hovering above the alter (the soul of the airplane's original owner?) will follow you, making strange noises. The cloud is harmless, but it may "cloud" your vision.
Completing the Mountains of Madness (returning to the plane with the keys), will end the game, restart the player with default spawning statistics (i.e. 3 HP, 0 artifacts, 0 items, etc.), and will wipe all progress - in other words, completely restarting the game.
- If the player wants to experience the Mountains of Madness and return without wiping their game, search for the hidden book portal found somewhere in the bottom tenth floor. The player may have to use Dynamite or a Pickaxe to find the hidden room where the book portal is, much like the hidden Dusty Books that access the Shadow World. The book should show up on the mini-map as an exit if the Compass is equipped.
- Regardless of whether you pick up the keys, the black cloud will not follow you back to the Library or any other world.
- If you pick up the keys before leaving, you may return to the bottom floor of the Mountains of Madness from the Library at a later time. This is useful if you wish to get the R'lyeh Nice to Meet You and What Final Horror achievements during the same run.
- If you do not pick up the keys before leaving, returning to the Mountains of Madness will start you on the top floor beside the plane.
- If you do not intend to return to the Mountains, you still retain all of the items and upgrades you acquired there.
Trick or TreatEdit
A Jack-o'-Lantern can be found in the Library canteen. Activating the Jack-o'-Lantern will send the Explorer to a mostly barren, dimly-lit world, a single level three floors high.
There are only two Denizens that may be encountered in this world: Jack-o'-Lantern Cultists and Shoggoths (lots of Shoggoths).
This world contains plenty of Artifacts, Keys, Items, food, and ammo. There are small Jack-o'-Lanterns that can be destroyed to yield Artifacts. There are assorted piles of weapons and tools from all previous worlds. A random Prayer Alter will be present on the second or third floor, granting magic if prayed to.
Unfortunately, guarding all this bountiful loot is a large number of Shoggoths, typically 3-4 per floor. These are not only invincible but especially fast (probably from all the sugar), often requiring the Explorer to grab whatever loot is found and run for it.
Escaping this world is done by activating a giant Jack-o'-Lantern located on the bottom floor, which will take the Explorer back to the Library along with any loot they're carrying. The Jack-o'-Lantern may be re-entered in the same run just as the other Worlds, allowing Explorers easy access to much-needed resources.
Like the Mountains of Madness levels and the Asylum, the Trick or Treat world is completely optional if the Explorer intends to collect all three Souls.
- Developer dphrygian described Trick or Treat upon release as "[t]his spooky level is absolutely packed with loot. Use it to gear up for adventure! Or work on that 9,999 artifacts achievement."
"The definition of insanity is doing the same thing over and over and expecting different results." - UnknownThe Asylum expansion is a maddening challenge level entered either via an orange-glowing Strange Book in the Library or resurrected into after dying in a failed run. Full of some of the most dangerous Denizens and nastiest hazards in the game, the goal is to rescue as many Lost Souls as possible, portrayed as white, glowing spheres sometimes trapped in the terrain. If the Explorer successfully ascends three levels they will be able to release the Lost Souls via the Soul Grinder.
Upon entry the Explorer is deposited in a long hallway with one book on either side and a smokey, red-sparkling portal at the end of the hall. To the right is the Asylum Leaderboards book, while the Strange Book to the left allows exit to the Library.
Once the portal is entered a three minute timer (located beneath the map) starts counting down. Once the timer reaches zero an unthinkable entity escapes the central prison (seen on the second floor of every level the Explorer ascends and marked on the map as a black square) and begins chasing the player in an inky cloud of gurgling teeth, including through locked doors, walls, hazards, and any other obstacle. Lost Souls can continue to be collected, but with far greater risk.
- Denizens encountered: Mummies, Flying Eyeballs, Bugs, Fire Bugs, Cultists, Lizardman Statues.
- Hazards encountered: floor spikes, wall spikes, false tiles; extreme falls
- A new magical ability exclusive to Asylum, Soul Trap, can assist in collecting Lost Souls by destroying Denizens, but at the cost of 10 Artifacts per cast. This Prayer Altar is not guaranteed to appear.
- A new, exclusive piece of gear, the Soul Stone, increases the worth of Souls, but like Soul Trap there is no guarantee of it spawning.
A successful run will always respawn the player back in the starting hallway; a death will provide the option to resurrect in Asylum or the Library. Either way upon respawning all items, magic, and weapons are reset as with any new game. Players may view their score in the Leaderboards book on the desk to the right of the Library's Mirror.
