Rust Design Notes

The book's foreword notes that Scientist NPCs were deliberately designed to contrast sharply with scavenger-like players: a dystopian, militaristic look inspired by HAZMAT suits and tactical gear, meant to hint at Rust's wider lore without any explicit storytelling.

Early Bandit concept art deliberately kept their faces covered while the team weighed a few different backstories for them: a militia group, abandoned laborers, or black-market arms dealers using the island for business.

Cut from the carcass of a wolf or bear, this headdress has stayed an early-game favorite for its combination of high protection and low cost.

A climbing boot built around a primitive crampon was concepted but never made it into the game.

Early heavy-armor concepts explored turning Oil Barrels and Gas Canisters - both already common, readily available props - directly into wearable heavy armor.

Early Heavy Metal Armor sketches were inspired by the real 19th-century Australian outlaw Ned Kelly, who famously wore homemade plate armor - reimagined here as slabs of thick scrap metal forming a primitive bulletproof suit.

The Lighthouse was among the very first monuments ever added to Rust. Before the game had an in-game map, its original purpose was purely practical: a fixed, visible landmark players could use to navigate the island.

Some train car concepts were purpose-built as bases-on-rails - designed specifically for players to build defensible structures on top of, effectively creating rolling reinforced fortresses.

Underwater Labs was concepted as a sci-fi, pod-based research facility for an in-universe company called Cobalt: bulkhead corridors, reinforced glass, and a submarine bay, all styled with a clinical, high-tech-gone-corroded look.

Concept art made for Underwater Labs depicted research tanks holding live sharks, hinting at ethically-gray experimentation by Cobalt. The idea never shipped - the Shark that swims Rust's oceans today is unrelated wildlife, not a lab escapee.

A retrofitted train car turned mobile casino - nicknamed the "Lucky Caboose" in its concept art - was designed with a fairground look: scavenged fairy lights, hand-painted signs, worn poker tables, faded slot machines, and an automated blackjack machine built from salvaged 1980s tech. It never made it into the game.

Vault Entrance concepts drew on Cold War bunkers and fallout-shelter architecture, meant to look fortified enough to make players curious about what they were guarding. The monument type was never built.

Early Church concepts blended Brutalist and midcentury industrial architecture with religious grandeur - raw concrete, steel, aged brick, tall narrow windows - but the monument type was ultimately cut.

An unbuilt Town Hall monument was inspired by a real train terminal near Facepunch's own office. Its Brutalist, civic-administration design implied it once ran city infrastructure - or Cobalt operations.

Zenlabs is the in-universe company whose Brutalist, monolithic buildings deepen the Scientists' backstory - the heavy, authoritarian architecture is meant to project control without a word of explicit dialogue.

The Zenlabs Kiosk was concept art for an early, unbuilt idea: an interactive hub where players could take on tasks from the Scientists in exchange for valuable resources - essentially a cut quest system.

In-game propaganda posters flesh out Cobalt as a sprawling conglomerate with at least four public-facing divisions: a Nuclear Project ("Safe. Efficient. Clean."), a Bio-Research Division ("Giving Nature a Helping Hand"), a Genetic Research arm, and a Space Center ("Answers Are Out There") tied to "Project Nova."

The Triangle Foundation was added to break up the rigid layouts forced by square foundations. Its extra structural variety led to players unintentionally discovering honeycombing - now one of Rust's most iconic defensive base-building techniques - as a side effect the designers hadn't specifically planned for.

The Sorting Adaptor's designers had to make genuinely impossible tech - a device that automatically sorts loot into the right boxes - read as clear and usable despite that. Their solution for the related Sorting Pipes system was simple: color-code the pipes so the flow of items stays easy to follow even when a base's sorting network gets complicated.

Despite being a purely back-end gameplay object governing base ownership, the Tool Cupboard's design was deliberately built to feel like a believable, physical object - the book describes it as "the beating heart of any base." The Retro TC skin reimagines it as an old filing cabinet stuffed with scavenged monitors and electronics.

The chapter introduction frames Rust's whole weapons aesthetic as "makeshift realism": early concepts focused on materials a survivor could plausibly scavenge - scrap metal, pipes, rope, duct tape - assembled with grit rather than polish.

Rust's most iconic weapon started from a familiar shape: early Assault Rifle sketches took the classic AK-47 silhouette and reimagined it through scavenging, improvisation, and wear.

SMG concepts drew on WWII-era M3 "Grease Guns," exploring different takes on a simple, spring-based fully-automatic firing system.

LMG concept art built its oversized ammo box out of a child's lunchbox, complete with scratches, wear, and grime - a small, very literal example of the "scavenged from anything" design rule.

Concept art for the Grapplehook Gun describes it as originally intended purely as a traversal tool - for swinging across gaps and climbing - rather than the more combat-flexible role it plays today.

Unlike hand-built tools like the Stone Pickaxe, the Jackhammer was deliberately designed to look factory-made but well-aged - a visual cue that it's meant to read as a rare find you loot, not something you cobble together.

Flamethrower concept art explored two distinct versions: a crude, scavenged build from a fuel pump, blowtorch, and copper plumbing, versus a separate military-grade design built specifically for Cobalt's Scientists.

A dedicated Grenade Launcher - built around a compressed-air canister firing Bean Can-style projectiles - was concepted but never shipped.

CAML was a cut concept for a military quadruped drone, deliberately designed to look less like a sleek war machine and more like a reclaimed agricultural or mining robot.

An unshipped Underwater Drone concept imagined a bulky, DIY remote-controlled submersible built from a milk crate, a flashlight, and a grabber arm for interacting with underwater loot.

The chapter introduction sums up Rust's vehicle philosophy in one line: every vehicle should look assembled from scrap, with patched panels, exposed engines, and worn parts, as if it were built or repaired in the field rather than manufactured.

Early Raft concepts explored a fully modular build system, similar in spirit to the modular car - but it proved too ambitious for the time and was shelved. The Rafts that shipped instead lean into a simpler handmade look: mismatched planks, patched sails, and steering tools improvised from brooms or shovels.

Rust's Submarines were inspired by the real WWII-era X-class midget submarine, reimagined from old storage tanks, rusted valves, and welded pressure seals.

A vintage Cessna-inspired Airplane was concepted as a long-distance, high-speed travel option, but it never made it into the game.

The Camper was envisioned as a mobile base extension with a pop-up roof inspired by real camper vans. The pop-up mechanic added a lot visually but was ultimately scrapped.

Several dedicated Truck variants - tailored to transport, water hauling, cargo, and defense roles - were concepted but never shipped.

Early Tank concepts imagined heavily modified war relics welded together from industrial parts and salvaged steel - bolted-on plates, repurposed farm treads - blending military hardware with Rust's scrappy improvisation. The vehicle type was never built.

The Spacesuit was the very first experiment with an alternate look for the HAZMAT Suit. It was greenlit once Cobalt's Cold War-era, high-tech-corporation lore was established, reimagining radiation protection with a retrofuturistic edge.

The Clatter Hat DLC was built to promote Clatter, a separate Facepunch game about commanding customizable squads of fighting robots - its designs are lifted straight from Clatter's own character roster, restyled to fit Rust's scrappy aesthetic.

A Yeti enemy was concepted for a winter event tied to the Ice King DLC pack, but it never made it into the game.

Rust's own Frankenstein character was introduced as part of the game's first-ever Halloween event, alongside a Frankenstein Table that lets players assemble their own Frankenstein-style helper.

The Sunburn DLC's Water Guns and Water Pistols started as purely playful, nonlethal cosmetics - but a later update let them spray radiated water, giving the joke items a genuine use in traps or against other players.

The Abyss DLC pack's underwater-themed weapon dressing included an unused Octopus Rifle skin, alongside the Speargun and Abyss Assault Rifle that did ship.

Several Tool Cupboard reskins were explored but never shipped, including a kid's-toybox version covered in crayon drawings and handprints, and a pencil-topped locker design.
