''Strange Adventures In Infinite Space'' is a freeware game made by Digital Eel Games.

In the game, you control an {{AFGNCAAP}} spaceship captain hired out by a [[TheSyndicate shady "businessman"]] to explore a region of space known as Sector Prime on a ten-year charter. Along the way, you explore new solar systems, discover exciting new technologies, and find new alien races to talk to (or kill). At the end of the ten-year period, you are expected to return home with loot and tales from your [[TitleDrop strange adventure in infinite space]].

...And that's it, really. The game takes about 5-15 minutes to complete, but it's strangely compelling nevertheless.

It has spawned a sequel of sorts (Although it is more of an EnhancedRemake) called ''Weird Worlds: Return to Infinite Space''. This installment is not freeware, but contains the stuff the original had, and a lot more, including GameMod support.

Not to be confused with InfiniteSpace by {{Sega}}.

''Strange Adventures'' is available [[http://www.digital-eel.com/sais/ here]]. ''Weird Worlds'' can be bought from Digital Eel's [[http://www.shrapnelgames.com/Digital_Eel/WW/WW_page.html webpage]], as well as {{DESURA}} and {{Steam}}.

A third game, ''Infinite Space III: Sea of Stars'' is under development after a successful [[http://www.kickstarter.com/projects/digital-eel/infinite-space-3-sea-of-stars Kickstarter campaign]]. It can be purchased on Steam Early Access.

''StrangeAdventuresInInfiniteSpace'' provides examples of:

* AbsoluteXenophobe: The Tan Ru are {{mechanical lifeforms}}, and will want to kill you for not being the same.
* ApatheticCitizens: If Esmeralda doesn't steal anything but the ship's towels, the message about her says that some of the crew "thought they had seen her aboard". They saw a notorious and wanted thief roaming the corridors of the ship, and simply thought nothing of it until she absconded with her haul.
* ApocalypseHow: Several. Stars can go nova, destroying all the planets in the system (and your ship, if you get caught in the blast). One alien artefact is capable of destroying absolutely ''everything'' within a 5 light-year radius; fortunately, you can set the timer for as long as you want. Finally, two alien races [[spoiler: will systematically destroy planets in a path that ends with your own home system]] unless you manage to defeat them.
* TheBattlestar: The Garthan Light Carrier doesn't really qualify as its weapons only include a pair of weak missile launchers. The Urluquai Carrier definitely qualifies, though. It also has the bonus of being able to cloak until it appears right under your nose to blast your ship to smithereens.
* BlueAndOrangeMorality: Most hostility will come with messages to the effect of "We're going to kill you now", but the Urluquai will send friendly messages inviting you to join them in "play among colors and light". This still means "We're going to blow you to bits", they just have a very strange way of thinking about it.
* CharmPerson: The Mantle of Babulon is recognized, and received in friendship by most alien species as a sign of power and authority, even the ones that normally hate you unconditionally. The only ones to reject it are the Tan Ru and (in ''Weird Worlds'') the Tchorak (because you're still organic and carbon-based life, and that angers them) and the Kawangi and (''Weird Worlds'') Ravians, who are big OmnicidalManiac invasions.
* ClassyCatBurglar: Esmerelda in ''Weird Worlds''. She will randomly steal an item in your cargo hold (except the Klackar Beacon) and sell it to one of the races (you can later find it on their homeworld). The only way to stop her is to have one of two items (you can guess by their descriptions: Lookout Frogs and Toy Robot. In that case, Esmerelda is captured and you can turn her in at the end of your mission for a 500 credit bonus. If you don't have anything for her to steal, she'll steal all towels on the ship instead.
* DoomsdayDevice: The Limited Vacuum Collapser, which destroys a five-lightyear radius of space when activated. Give yourself time to be further away.
* EarthIsTheCentreOfTheUniverse: Averted by name (the human homeworld is Hope), but played straight nonetheless. The Kawangi and Ravians both make a beeline for Hope, though they have no issue with humans in particular. It's the done thing for drama.
* EarthShatteringKaboom: Occasionally, stars will go nova, meaning you better get the hell away, unless you have a Temporal Flux Shield. The Yellow Kawangi ship is also capable of blowing up stars. If you happen to get the Limited Vacuum Collapser, you can create an even larger explosion that will destroy anything in a five-lightyear radius.
* EarthThatWas: The PlayerCharacter comes from the planet Hope in the Glory system, the "new homeworld" of humanity. It's not mentioned why there needs to be a new homeworld. "Old Earth" is only mentioned once, if you happen to find the Golden Cannister from a Voyager probe, containing the Golden Disk, and is stated to be very far away.
* FasterThanLightTravel: Of course. Different engines allow your ship to travel at different speeds. Maximum speed for you is 20 times the speed of light, but some alien species seem to have the technology to spontaneously warp to places on a whim.
** Unless you're lucky enough to obtain the hyperdrive, which instantly transports you to any star, although you have to wait 60 days for it to recharge afterwards.
** If you happen to obtain the Aethric Mirror, you can use it to instantly swap places with any fleet you have detected. With a bit of creativity, you can destroy any enemy fleet this way.
* GenieInABottle: Breaking the Timeless Bauble releases one. He will offer you an item of your choice as a reward, which you must then type in. If you misspell, he will say he has no idea what you mean and give you a useless item instead. Even if you get the name correct, you may not always get the item. This may be dependent on whether or not it's a rare item that already exists in the game and cannot be duplicated. You may also, sometimes, ask for an item that would not normally be available to you.
* TheGreys: The Zorg, more or less.
* GhostShip: Space hulks can be found drifting around some planets. Board them and loot them if you want, but beware of automatic weapons systems.
** [[BigBad Primordius']] entire fleet is made out of literal ghost ships.
* GodzillaThreshold: The Limited Vacuum Collapser [[ApocalypseHow wipes out everything within five parsecs]] when it blows up. Causes mass destruction, but it's a useful solution to the [[StarKilling Kawangi incursion]].
* HoistByHisOwnPetard: A good way of dealing with the Kawangi, who move from system to system, blowing up stars. If you happen to have the Limited Vacuum Collapser, you can use it to cause a star to go ''super''nova, destroying anything in a five-lightyear radius after a specified time limit. So, pick a star in the Yellow Kawangi flight path, activate the LVC, and run like hell.
* HordeOfAlienLocusts: Ravians. They come from another galaxy in a powerful ship and move from planet to planet, consuming everything and blowing up the stars on their way out.
* InsectoidAliens: Ravians.
* LateToTheTragedy: Many events give off this feeling.
** [[VideoGame/DwarfFortress The Underdelve]]
** The Epsilon Research base
** "The Lesser Swarm"
** The three abandoned ships found in the game all give off this vibe. Damocles is given some backstory, though.
* MacrossMissileMassacre: The Multi-missile weapon does this. Effective against all kinds of enemies.
* MechanicalLifeforms: The Tan Ru, described as a race of sentient machines who are [[BlueAndOrangeMorality "oblivious to organic life."]] They attack on sight.
* MultipleEndings: What happens to you in the aftermath of your voyage depends on your score at the end. Interestingly enough, you can get an overwhelmingly high negative score (and a bad aftermath) by arriving home late even if you literally saved the galaxy.
* NonstandardGameOver:
** It is possible to use the Limited Vacuum Collapser to destroy your home star, Hope. The game will end even if your ship escapes the explosion unscathed, and a depressing Game Over message will explain why.
** Retiring from the game if one of the "plots" is active - the coming of Primordius, the Ravian swarm, or the Kawangi invasion - will tell you that they killed everyone, so your ending is moot.
* NoWarpingZone: Nebulae limit cruising speed to the speed of light, except with certain engines.
** Strangely enough, even if you have the Nebular Prow installed, which pushes nebular matter aside, your ship still moves slow. After this, though, you can move at normal speed.
* OmnicidalManiac: The Kawangi are a race said to "wreak wanton destruction on a galactic scale." They aren't kidding; [[spoiler:they're capable of [[EarthShatteringKaboom blowing up entire Solar Systems]]]].
* OneHitKill: The Chromium Gong will destroy the strongest enemy on the field once per battle. This includes bosses.
* ProudWarriorRaceGuy: Garthans. Aggressive and dangerous, whether they're on your side or not.
* ProudMerchantRace: The Klackar. Invaluable allies in trade, since they trade items with you on 1:1 basis, no matter the value of the item you give them. Although, technically, you can summon them in the middle of a battle, and they will fight, they loathe fighting, and so are not good at it, getting killed easily. They will also demand payment for getting called into a firefight. If you don't give them something, they will leave, but take their beacon with them, so you can't call them again.
* RammingAlwaysWorks: Subverted. When two ships collide, this usually results in one of them (often, both) being destroyed or heavily damaged. Unfortunately, it happens a lot. The only exception are ships specifically designed with ramming in mind (e.g. Garthan ships, the ''Damocles'').
* RandomNumberGod: The galaxy is randomly generated at the beginning, meaning you have no idea where all the goodies are. Additionally, trying to ask for something specific from the guy in the Timeless Bauble can either result in you getting the item or getting something useless instead.
* TheReptilians: Garthans.
* ShootTheShaggyDog: In any game where the Kawangi or Ravians enter, or [[NamesToRunAwayFromReallyFast Primordius, Dread Lord of the Dark Traverse]] is prophesied to return, the ending becomes this if you return home without defeating them, because they destroy Hope anyway (Primodius will destroy [[TheEndOfTheWorldAsWeKnowIt the galaxy]]). All that hard work for nothing!
* SpacePirates:
** Can be hired to join your flotilla.
** If you're playing the original, or take the Pirate Corvette class in ''Weird Worlds'', ''you'' are one. Whether you [[ThePiratesWhoDontDoAnything do any pirating or not]] is up to you.
* SpaceWhale: They appear in a random event. Seeing them is apparently rare and considered a good omen.
* StealthInSpace: The Plasma Coil Cloaker. Besides being able to be used on a player's ship, it's also present on some Urluquai ships.
* ShoutOut:
** Several of the stars in the sector are usually named after science fiction authors including Creator/ArthurCClarke, Creator/LarryNiven, Creator/CliffordDSimak and Creator/RobertHeinlein. Also, some stars might be named after Creator/DanAykroyd and Creator/JohnBelushi, perhaps because the devs were fans of ''Film/TheBluesBrothers''.
** The Purple People Eater. Its description even lists it as being one-eyed, one-horned, and winged (i.e. "flying").
** The Monolith from ''Film/TwoThousandOneASpaceOdyssey''. Find it on a planet and its discovery comes with a kettle-drum theme to evoke ''Music/AlsoSprachZarathustra''.
** If Esmerelda doesn't find anything to steal in your cargo bay, she'll take all the ship's towels, possibly a reference to their importance in ''Franchise/TheHitchhikersGuideToTheGalaxy''. A definite reference is a time capsule with "a pair of peril-sensitive glasses, a useful towel and a note inside reading 'So long, and thanks for all the fish.'"
** The Tan Ru are named after an alien probe that fused with the Nomad probe in ''Series/StarTrek''.
** One black hole name is [[Franchise/CthulhuMythos Azathoth]].
* StarKilling: As {{Omnicidal Maniac}}s, the Kawagai provoke supernovae in stars along their path. The Ravians do as well.
* TimedMission: You have 10 years in the original, or 10, 20 or 30 in ''Weird Worlds'', to explore the entire sector. Best get crackin'!
* WaveMotionGun:
** The Particle Vortex gun makes every other weapon in the game look like a toy. Works well on fighters and corvettes.
** The Chromium Gong can OneHitKill ''any'' ship, although you can only use it one per battle.
** The Nova Cannon comes close. It's a Kawangi weapon that can OneHitKill a good number of ships and has a decent rate of fire. The only way to get it in the main game is to break the Timeless Bauble and ask the guy inside it for the weapon.
* WeComeInPeaceShootToKill: The battle cry of the Urluquai. They seem pleasant right up until they start shooting.
* TitleDrop: Every ending features the words "Thus ends your strange adventure in infinite space."''
* TwoDSpace: Played dead straight; ships will even ram other ships, without the ability to avoid each other.
* UnrealisticBlackHole: You can occasionally encounter black holes on your journey, in which case the game will offer you the chance to turn back. Apparently, even if you're travelling faster than light, you can still be pulled into them and destroyed. However, if any of the ships in your fleet have the Anti-Graviton Shunt, black holes got nothing on you. You can even travel to their systems, although you won't find anything. Some playthroughs put an extra black hole that is home to [[EldritchAbomination Primordius]], whom you must defeat in order to win the game.
* AVillainNamedZrg: The Zorg are an alien race in both games. They aren't exactly villains, though. Just... alien.
** They can still attack you, if you show up unannounced at their doorstep. They'll usually give you a chance to leave first, though. If you happen to have hired a Zorg ship, they'll instantly turn friendly.
