You're an intrepid space captain, one of the last humans left, exploring the galaxy.

You're an android warp engineer, having secretly modified yourself to achieve sentience.

You're the ship's medical officer, a powerful psychic alien of an unknown race.

You're an [[{{CaptainErsatz}} Alien]] stowed away in the ventilation systems.

Whatever you were, now you've crashlanded on the planet of Notrium, shot down by a mysterious automated missile defense system.

Notrium is a Freeware Survival game by Ville Mönkkönen, where the player must gather food, fight off hostile alien predators, and survive the freezing cold nights, all whilst trying to gather the scattered remains of technology from your destroyed spaceship to cobble together something to defend yourself with.

Will you repair your escape pod and flee the planet? Send a distress beacon for help? Or will you discover the secrets of planet Notrium?

This website also has a couple mods which can significantly add functionality to the game.

!!''Notrium'' features examples of the following tropes:
* ActionSurvivor: The Captain is hardly an action hero, punching things hurts him as well as his target, and he has the second lowest health of the characters.
* AsYouKnow: Many important tidbits of information, including incredibly important item crafting recipes, are revealed to the player through character journals viewed over the passage of in-game time. This can lead to a situation where a new player unfamiliar with combinations can be holding all the ingredients to create a temperature regulating Stasis Tent, and then die of hypothermia ''because the character hasn't told themself the recipe yet''.
* AwesomeYetPractical: The Sniper Pistol - you have to make the gun from scratch, and manufacture every bullet by hand, but it takes down most things on the planet in one shot. It's also useful for RecoilBoost.
* BoringButPractical: The Welding Torch. It never runs out of ammo (one of the only weapons that doesn't use it), does more damage and has a longer range than punching, and can break open storage containers containing valuable survival supplies.
* BottomlessBladder: Possibly why dying of thirst is one of the only things that ''isn't'' in the game.
* CommonplaceRare: Justified, marooned on an alien planet, things like basic rations, lighters and bullets are all hard to find and invaluable.
* EverythingTryingToKillYou: You can die from heat stroke, hypothermia, starvation, torn apart by aliens, shot down by missiles, electrocuted by robots, or even burned to death before you even manage to set foot on the planet.
* GameMod: The game is highly moddable and has several of the more prominent mods hosted by the creator.
* GuideDangIt: Many of the game's most powerful recipes are rather obscure. The pulse laser, in particular, [[spoiler: is made from a laser pistol (which is pretty easy to build and told to you in the description for light diodes) and a glass marble, which can only be made with sand from the missile base and must be "U" used around a fire with a welding torch in your hand. There is nothing in the game that would guide you to this conclusion, and as glass marbles are an essential ingredient to omni-directional light diodes and advanced turrets. Pulse lasers are also essential for making the laser shotgun, and are essential when fighting some of the more powerful baddies in Notrium.]]
* ItemCrafting: Vital to every character. Most equipment must be created from scratch from salvaged materials.
* MegaCorp: Ville Corp, which is plundering the wealth of the planet, and their mercenaries are not happy with your presence.
* MoreDakka: The Pulse Laser and Machine Pistol are all about this.
* MultipleEndings
* NintendoHard: You will die many, many times.
* PsychicPowers: The [[ExactlyWhatItSaysOnTheTin Psychic]] has them.
* {{Roguelike}}: Shares many similarities, though a non-turn based example.
* SamusIsAGirl: [[spoiler: The Alien is an egg-laying female.]]
* ShotgunsAreJustBetter: Averted. Whilst the Pebble Shotgun is a decent weapon (and requires very few resources, which is important), it deals fairly low damage compared to other guns. Justified, since it shoots pebbles.
* UnexpectedGameplayChange: The Psychic's entire game experience is radically different from the game's other characters, as he cannot carry items, use weapons or make use of most items of technology, making his game experience so different, he even gets his own version of the game's tutorial.
* VideoGameCaringPotential: As android, human, or psionic, you can find little bases guarded by turrets and with stasis fields for you to use. These bases will contain some of the people from your ship, and can and will follow you. They ask if you have a better secured base for them to use, as the one they have won't last long. You can take them to safety.
* VideoGameCrueltyPotential: You can drag these allies to alien-filled deathtraps and leave them to die. When you first land on the planet, you're confronted with an angry hermit, whose house your escape pod landed on. You can either give him some of your scavenged survival supplies or....
* VideoGameCrueltyPunishment: For the Captain only, [[spoiler: killing the Hermit deprives you of the chance of getting the best ally in the game]]. On a lesser note, kill the hermit, and his bloody body will stay on the ground where you killed him forever. If you intend to use his house as a base, it can be quite sad to see it.
* VillainProtagonist: The Alien intends to use the planet as its base to create a conquering brood.
* WeakButSkilled: For its race, the Alien. A journal entry mentions that it was born small, weak and unfit, and had to use cunning and guile to defend itself from the other members of its brood who wanted to kill it.
* WizardNeedsFoodBadly
