PDA Log

PDA Notifications

Introduction

TriggerDialogue
Opening PDA first time"You have suffered minor head trauma. This is considered an optimal outcome. This PDA has now rebooted in emergency mode with one directive: to keep you alive on an alien world. Please refer to the databank for detailed survival advice. Good luck."
Lifepod 5 systems repaired"Lifepod secondary systems online. Running full environment diagnostic and outputting results to databank."

Extra Triggers

TriggerDialogue
Spend 1 hour (Three days) in-game"Congratulations, survivor: you have exceeded your weekly exercise quotient by 500%. Data indicates that swimming was your favorite activity. Be sure to vary your routine for uniform muscle development."

Habitat Compartments

ConstructDialogue
Alien Containment"Aquariums provide an ideal opportunity to study alien fauna up close. Select carefully which lifeforms you bring onboard - they may also be studying you."
Bench"Warning: endorphin levels low. Consider taking a seat and meditating. It may help to remember that problems exist only where you choose to see them."
Bioreactor"A reliable power source is a critical step toward self-sufficiency. Consider keeping a photo-journal of your achievements to motivate you in times of despair."
Exterior Growbed"Farming alien plants is a proven survival strategy. Craig McGill survived 47 months on a healthy, raw salad of live tree-roaches and stankroot."
Moonpool"After weeks without human contact, it is normal to experience psychological discomfort. Research indicates symptoms may be partly alleviated by adopting a pet, or anthropomorphizing an inanimate object."
Multipurpose Room"It may be prudent to separate work and leisure spaces to maximize productivity. Treat this space as your home, but never forget that it is not."
Nuclear Reactor"Exercise caution when handling radioactive materials. Exposure risks corrupting your PDA's recording of the circumstances of your death."
Observatory"Unless constructed with a specific research task in mind, observatories and other glass modules are imprudent for survival purposes."
Window"Windows improve the aesthetics of your habitat, at the expense of structural integrity."

Tools

ConstructDialogue
Habitat Builder"The builder tool is designed to construct habitats capable of withstanding extreme environmental conditions."
Survival Knife"Weapons were removed from standard survival blueprints following the massacre on Obraxis Prime. The knife remains the only exception."
Scanner"The scanner can be used to synthesize blueprints from salvaged technology, and to record alien biological data."
Stasis Rifle"Motivational note. Craig McGill crash-landed in the acid swamps of Boreal 9, fought off arachnid kidney-poachers, and hijacked a tame starwhal. If he can do all that, you can survive one more day."

Basic Materials

CraftDialogue
Bleach"Bleach is an essential chemical used for cleaning wounds and purifying water."
Lubricant"Lubricant is essential in construction of vehicles and power plants."

Raw Materials

ObtainDialogue
Copper Ore"Copper is an essential component of all powered equipment. Your probability of survival has just increased to: unlikely, but plausible."
Diamond"Remember that materials you gather are the property of the Alterra corporation. You will be liable to reimburse the full market price. Your current bill stands at 3 million credits."
Silver Ore"Silver-based wiring kits are an essential component of many habitat modules."

Equipment

TriggerDialogue
Crafting a pair of Fins"The fabricator draws from available data to provide environment-appropriate equipment, using locally available materials. For your safety this setting cannot be overridden."
Crafting a Radiation Suit"The status of the Aurora's crew, and the ship's long-range comm relay, is indeterminate. Exploring the crash site may provide further information."
Receiving Radiation Suit Blueprints following the Aurora explosion"For your convenience the radiation suit has been added to your blueprint database."
Equipping a Water Filtration Suit"Stillsuit equipped and capturing body moisture. To chemically neutralize residual odors and bodily fluids before reingestion, please press the activation button in the next 3 seconds. You have chosen not to activate chemical taste neutralization. Thank you and have a nice day."

Vehicles

ConstructDialogue
Cyclops"Be advised: the Cyclops is designed to be operated by a three-person crew. Only experienced helms-people should attempt to pilot this vehicle solo."
Prawn Suit"It is normal when first piloting a Prawn suit to feel a sense of limitless power. Prawn operators receive weeks of training to counteract this phenomenon. You will have to make do with self-discipline."
Seaglide"The Seaglide will increase your effective exploration range. For your safety please pack food and water for long journeys, and stay within 5km of the nearest lifepod or habitat."
Seamoth"The Seamoth is a fast, safe mode of transport, but remember that swimming is good for your glutes and endorphin levels."
Neptune Escape Rocket (Completing)"Neptune 1 rocket online."

Self Scans

TriggerDialogue
First scan (no other scan requirements triggered)"Performing self-scan. Vital signs normal. Detecting trace amounts of foreign bacteria. Continuing to monitor."
Second scan (after going to the Aurora or entering the Mountains)"Performing self-scan. Detecting statistically significant bacteria levels. No adverse effects detected. Be vigilant for symptoms."
Third scan (attempt to disable the Quarantine Enforcement Platform or entering the Lost River)"Performing self-scan. The bacterial infection in your system has progressed. Detecting skin-irritation and immune system response. Further data required to identify bacterial strain."
Fourth scan (at the Disease Research Facility or upon reaching 1000m)"Performing self-scan. Bacterial infection has spread to the skin and pulmonary system. It is imperative you find a way to neutralize the infection."
Final scan (after being cured using Enzyme 42)"Performing self-scan. Vital signs normal. No remaining sign of bacterial infection."

Fish & Food

TriggerDialogue
Picking up a Bladderfish"Alien lifeforms may have unexpected applications. Utilizing alien resources is a proven survival strategy."
Cooking a Garryfish"It is common for those accustomed to synthetic foods to be repulsed by eating an animal carcass. Remember that humans survived this way for millennia. You can too."
Cooking a Hoverfish"Consider disguising the flavor of unsavory meats with salt, or locally sourced herbs and spices."
Cooking a Peeper"The fabricator cooks small organisms, while disposing of the skeletal structure, bodily fluids and internal organs, thus rendering them safe for human consumption."
Acquiring some Disinfected Water"Preparing the day's water ration, ahead of time, will help ensure against dehydration, and eventual death."

Biomes

BiomeDialogue
Blood Kelp Zone"This ecological biome matches 7 of the 9 preconditions for stimulating terror in humans."
Bulb Zone"Detecting volcanic activity, and several unusual electromagnetic signatures in the region. Exercise caution when diving deeper."
Crash Zone"Lifeform readings in this region are sparse. The Aurora's radioactive fallout will have devastating effects on the alien ecosystem if not contained within the next 24 hours."
Crater Edge"Warning: Entering ecological dead zone. Adding report to databank."
Deep Grand Reef"Detecting a titanium mass somewere in this area. Unable to confirm whether it originated on the Aurora."
Dunes"Detecting multiple leviathan class lifeforms in the region. Are you certain whatever you're doing is worth it?"

Jellyshroom Cave Entrance"Local scans show a nearby cave entrance, depth 90m, leading to an unknown environmental biome."
Jellyshroom Cave"The conditions in this cave support a microcosm of unique, possibly predatory lifeforms. Detecting an artificial structure somewhere in the region."
Kelp Forest"Life on this planet grows in distinct and diverse ecological biomes. Further study recommended."
Kelp Forest Caves"Be advised: a common complication for cave divers is loss of orientation, followed by eventual asphyxiation."
Lost River"Terrain scans indicate this biome contains unusually high concentrations of organic and fossilized remains."
Lost River (Opening)"Local scans show a nearby opening, leading to a biome with extensive fossilized remains."
Mountains"Detecting massive energy signature in the region. Cannot identify."
Mountains Caves"Local scans indicate an abundance of mineral deposits in this area."
Mushroom Forest"The biomass in this area is dominated by plantlife. Picking up faint Alterra vehicle signatures."
Mushroom Forest Caves"You are currently inside a long-calcified root system. Evidence suggests it was eaten away by other lifeforms over many centuries to form these natural caves."
Safe Shallows Caves"Detecting sulfur deposits in the local cave systems. Sulfur is an essential component of the repair tool."
Sea Treader's Path"Damage to plantlife on the seafloor suggests this may be the migration path of a huge, bottom-dwelling lifeform."

1 Hour and 30 Minutes after entering the Q.E.P. to at least past the first turn"This is Alterra HQ. This may be our only communications window. We can't send a rescue ship all the way out there so Aurora, you're just going to have to meet us halfway. We've uploaded blueprints to the ship's computer Offmic We're doing a sandwich run, are you in? Uh, yeah, give me a second. Blackbox data shows the high security terminal in the Captain's quarters is still functional Offmic Becky's leaving like in five minutes Alright tell Becky I'll just take the regular. Offmic The regular? Yeah, she'll know what I mean. Offmic And if she doesn't, Just tell her the regular dude. Offmic I say regular, and she's like what's the regular, and I have to come all the way back up here The code should be 2679 The regular's just a ham and cheese Offmic Ok, well would you just say ham and cheese?! Ham and cheese! Offmic Ok."
