Welcome to DERELIKT Field Guide

The full DERELIKT achievement list with current Steam completion rates, the missable ones and the fastest route to 100%.

The full battery puzzle: where the lug wrench is, which APC holds the cell, how to install it and why the achievement is called 1.21 Jiggawatts.

How DERELIKT actually works: dialogue, manual saves, the grid inventory, medkit merging, crowbar stealth and the settings worth changing before Level 1.

What the DERELIKT demo includes, what the full release adds, and whether your demo save or demo codes carry over.

Every document type, the 13 Shriver's Notes and the Bookworm and Librarian achievement thresholds, organised by level.

Every verified DERELIKT keypad, from the 0451 restroom to the Exo Labs server towers, plus which 'codes' are actually physical puzzles.

Glyph fragments, translation, engraving slots and the perk upgrades behind Max Power and Eyes on the Inside.

The terminal hacking minigame explained: how the password-narrowing program works, what terminals unlock and the 1337 Haxx0r achievement.

The hazmat suit's location in Central Security, the Squidbull requirement and the coolant rooms that are lethal without it.

What Insight does, how engraving slots work and the verified Insight locations, starting with the two on the Anomaly Surface cliff.

How the DERELIKT grid inventory works, why ammo stacks take a slot, how to merge medkits and when to dump loot at the hub.

The complete Von Neuman Outpost route: every crew conversation, the 0451 restroom, the flashlight run and the three Gun Nut quiz answers.

The reactor key, the three cooling stations, the alien cube choice and the meltdown run that ends with Dr. Shivers.

The last level: Dr. Shivers, the maintenance gauntlet and the two endings, including the secret ending achievement Enlightened.

Every step of the Anomaly Surface mission: mission reports, the monolith, Empty Proxy escapes, the Derelict Campsite rifle and Louis Hartman's battery job.

Exo Laboratories from the blue keycard to the upstairs survivor: the server-tower code, the sample-tube code and how the hub safe zone works.

Central Security's sentry gauntlet, the Executive Suites detour, the locked hazmat locker and the route back after the Squidbull.

Crew quarters, the bar, the kitchen noise puzzle, the gym survival fight and the route down the hole to the Squidbull.

The hazmat-gated coolant section: suit checks, flooded basins, alien stingrays, cooling towers and the long stretch with no save station.

How the reactor puzzle works: the three cooling stations, the reactor key, the core sequence and the meltdown escape that follows.

How to unlock the secret ending in DERELIKT: the alien cube, the glyph set, the NPC saves and the choice at the final boss.
