Demo Guide: Glyphs, Hacking & Tips

A practical DERELIKT demo guide covering Glyph slots, Insight, hacking software, combat pacing, and what changed in the launch build.

Start Here: What the DERELIKT Demo Contains

The DERELIKT demo drops you onto Von Neumann station with limited ammo, a demanding Glyph system, and a hacking puzzle that punishes random guessing. It matters because this is not a throwaway sampler: the DERELIKT demo asks you to make real build choices, manage finite resources, and learn the station’s rules before the full game opens up. Treat it as a compact survival-horror exam, and every Insight pickup, code lock, and firefight becomes a chance to improve your route.

The demo is a narrative retro FPS built around claustrophobic PS1-era sci-fi horror. You can install the free demo on Steam and play with English interface, audio, and subtitles. Its value comes from showing how the Glyph, hacking, and combat systems fit together, not from presenting a polished modern corridor shooter.

System	What the demo shows	Your first move
Glyphs	Stat-changing items found around the station	Inspect each glyph before spending Insight
Eye slots	Equipment slots with different focus options	Check which stat a slot sharpens before committing
Third Eye	A special slot that grants an ability based on the glyph inside	Test it with a glyph you are willing to move
Hacking	Code-combination puzzles with feedback after each choice	Deduce first; use software only when the pool stays wide
Visuals	Low-res and high-res modes plus optional warping and dithering	Set the look before you learn room details

The demo also uses a deliberately crusty look. You can switch between an era-accurate low-resolution presentation and a cleaner high-resolution image, and you can turn off texture warping and dithering if the swim becomes distracting. Those options matter because readability changes how quickly you spot pickups, terminals, and threats in tight rooms.

Glyph System Basics in the DERELIKT Demo

In the DERELIKT demo, the Glyph system is the main progression path after resources and weapons. Glyphs are found throughout the station and change player statistics once equipped. They go into eye slots, but not every eye slot is equal. Focusing a slot sharpens one stat of the Glyph imprinted there by 1, and the focus type is tied to the slot: damage, dexterity, or vitality. Focusing and unlocking new slots both consume Insight.

Term	What it does	Practical rule
Glyph	Carries a stat change when equipped	Keep the ones that match your weapon and survival needs
Eye slot	Holds a glyph; slots are not equal	Check the focus type before you slot a favorite glyph
Focusing	Improves one stat of the imprinted glyph by 1	Spend Insight only on a glyph you plan to keep
Insight	Currency for focusing and unlocking slots	Treat it as scarce; do not spread it across every experiment
Third Eye	Grants a new ability based on the slotted glyph	Use it as a build decision, not a spare slot

The Third Eye Is a Build Choice

The Third Eye slot is the part of the DERELIKT demo that most rewards curiosity. Depending on which glyph you place there, you receive a new ability. Some abilities are shown in action; the rest are left to discover. That makes the Third Eye a build-defining slot. If you move a glyph into it, ask whether you are chasing a specific ability or simply filling an empty socket. The former is a plan; the latter is how you end up spending Insight on slots you do not use.

Spend Insight Like It Is Ammo

Focus a slot only after you have a glyph that fits it. A +1 to a stat on a glyph you will replace is wasted.
Unlock a new slot when you already have a glyph ready, not because the menu offers it.
Test a Third Eye ability with a glyph whose stats you can live without for one room.
If a focus option does not match your current weapon or survivability, leave it alone.

Hacking Mini-Game: Solve Codes Without Wasting Software

The hacking mini-game starts with a simple goal: find the right code combination. Each selection returns information about whether your inputs are correct and whether they are in the correct part of the string. The efficient loop is deduction, not brute force. Read the feedback, eliminate impossible codes, and narrow the pool before you spend a finite disc.

Step	What you do	What you learn
1. Enter a candidate	Pick a code from the remaining pool	Whether any inputs are valid
2. Read position feedback	Check which correct inputs sit in the right part of the string	Which candidates can be eliminated
3. Narrow the pool	Cross off impossible codes	How close the remaining set is to a solution
4. Deploy software if needed	Use a Worm or Nuke disc during the mini-game	A percentage of incorrect passwords is removed immediately
5. Finish with logic	Use the smaller pool to make the final choice	You avoid burning a second disc on the same lock

Worm and Nuke Discs: Use Them Strategically

The DERELIKT demo includes hacking software discs such as Worm and Nuke. If you have one in your inventory during the mini-game, you can deploy it to remove a certain percentage of incorrect passwords with a click. The discs are finite. Use them when feedback still leaves too many candidates, or when a lock blocks additional resources or an access point. Do not deploy one on a puzzle you have already narrowed to a handful of codes.

Combat, Visuals, and Resource Discipline

DERELIKT is built for claustrophobic fights, so the demo rewards players who control distance and ammo. Do not treat every corridor as a firing range. Back away from open sightlines, clear rooms from thresholds, and keep a close-range answer for anything that closes the gap. The launch build makes Hard the recommended survival-horror difficulty, while ammo pickups now stack automatically. Reloading also returns the old magazine to your inventory, so top up before a fight instead of hoarding a half-empty mag.

The DERELIKT demo rewards this discipline because resources are not there to cover careless spray. If a room feels built to drain your ammo, disengage, check your inventory, and approach from a different angle. The same logic applies to Insight: every spent point should make the next room easier to read or fight through.

Visual Toggles That Change the Feel

Visual option	What changes	Pick it when
Low-res mode	Era-accurate crunchy presentation	You want the lost-1999-disc feel
High-res mode	Cleaner presentation	You want to read terminals and spot movement more easily
Texture warping on/off	Period-correct swimming textures or stable surfaces	You like the PS1 artifact or find it distracting
Dithering on/off	PS1-style texture treatment or cleaner gradients	You want the retro texture look or a more modern image

The look is not accidental. Static lighting was hand-painted, and the game uses dynamic subdivision that splits triangles as they get closer: one triangle becomes four, and four become 16. That technique produces the characteristic pop and wobble of PS1-era geometry. The demo lets you keep the crust or turn it down, so choose the setting that helps you play rather than the one that merely looks authentic.

Demo vs. Launch Build: What Changed

If the DERELIKT demo is your reference point, the launch build is not a one-to-one continuation. Several quality-of-life and difficulty changes landed after the demo period. The biggest are extra difficulty levels, automatic ammo stacking, broader camera sensitivity, full rebinding, more Glyph tutorialization, controller aim and zoom improvements, and bug fixes that include item overlap.

Change	What changed	Practical effect
Difficulty levels	Additional levels added; Hard is positioned as the survival-horror experience	Choose the pressure level deliberately
Ammo pickup	Automatically stacks with existing stacks	Less inventory juggling
Reloading	The old magazine returns to inventory	Partial mags are not wasted
Camera sensitivity	Improved range	Fine-tune look speed for tight corridors
Rebinding	Every keyboard and controller action can be rebound	Build a comfortable layout
Glyph tutorialization	More tutorial coverage	Learn focus and slot rules faster
Controller aim and zoom	Auto-aim and zoom corrections and improvements	Smoother controller play
Bug fixes	Item overlap and other issues fixed	Fewer inventory problems

For demo veterans, the practical takeaway is simple: do not carry old habits blindly into the launch build. Check the difficulty menu, rebind anything that feels wrong, and expect ammo to behave more cleanly. The core loop is unchanged: find glyphs, spend Insight, solve locks, and survive the station. The launch build simply removes some friction and gives you more control over how punishing the run becomes.

FAQ

Is the DERELIKT demo free? Yes. The DERELIKT demo is free to install and gives you an opening slice of the station, its Glyph system, and its hacking puzzles.

Does the DERELIKT demo include the Glyph system? Yes. You can find glyphs, equip them into eye slots, focus slots with Insight, and experiment with the Third Eye. Not every slot is equal, so check the focus type before committing.

What should I spend Insight on first in the DERELIKT demo? Focus a slot only when the glyph fits your current weapon and survival needs. Unlock a new slot when you already have a glyph ready for it. Treat the Third Eye as a build choice, because the ability you get depends on the glyph you place there.

What changed after the DERELIKT demo? The launch build adds difficulty levels, automatic ammo stacking, a wider camera sensitivity range, full rebinding, more Glyph tutorialization, controller aim and zoom improvements, and bug fixes. Hard is the recommended survival-horror difficulty.
