How do I do an "alien invasion" plot right?

>>54095745
Figure out what you're doing wrong, then remove that.

>>54095745
There's little chance of fending off a full invasion so make them basically petty raiders/the remnants of a failed and mostly destroyed expeditionary team.

They are, of course, still a fucking massive threat, but that would explain why they are at least stoppable. Or, you know, just weak enough to make you think you can stop them.

>aliens invade
How does your setting respond, /tg/?

>>54095847
Depends, what kind of aliens?
I mean, its mostly gonna be "WHAT, HOW, WHERE. SKYPEOPLE!?"

>>54095745

Nobody lives.

>>54095745
The aliens aren't necessarily malevolent, or at the very least they don't want to cause an extinction event. They're a business who wants to cut costs by rerouting their transport ships through our galaxy, and are invading in order to make absolutely certain that their big, obvious, and EXPENSIVE ships that are carrying their motherlode don't get nuked by the pre-ftl primitives panicking over their first contact.

>>54095745
Post-apocalyptic setting 1: scavenger hunt
The aliens have been beaten back but the earth is devastated and there are still the occasional isolated pockets of resistance here and there. You and your party are charged with avoiding/eradicating said pockets while harvesting bits and pieces of alien tech for the scientists to reverse engineer.

Post-apocalyptic setting 2: get to the choppa
The aliens are winning the war but there's a last ditch plan to save humanity - in a hidden underground base there's a colony ship loaded with tools, ultra-advanced weapons and enough plant and animal seed (including humans, of course) to restart civilization. It's set to teleport to a new planet on the other side of the galaxy in 10 days - can you and your party get there in time without getting killed or accidentally giving its location away to the aliens?

>>54095840
Alternatively the scraps of a fallen civilization trying to rebuild to their full glory, going from planet to planet looking for easy resources so they can conserve as much energy as possible. Earth is ripe with metals premined and refined, energy production (Even if its meager by comparison), and in a safe place to set up a temporary new home (Aka not in controlled space, hidden away from the aliens' enemy, and not in any danger from space objects. Only some shit ass little animals who barely figured out space travel and lasers.
Sort of like if you had to steal an animal den in a life or death situation, except you had a shotgun to one up whatever claws they had. Its not ideal but its better than nothing, worth the risk of getting killed.

>>54095847
We have the only spaceship planetside. Fortunately it's got a ridiculous amount of firepower. Unfortunately this entire dust up is going to fuck with the locals something hilarious. If this isn't the Gods going "fuck it" and wiping out our universe, anyway.

>>54095745
Make them raiders. There's honestly no believable way for humanity to fend off an attack by a race that has mastered star travel.

Even if we win, they just go back to orbit and drop rocks on us.

There's also the XCOM schtick, where they're 'testing' humanity to see if we'll make good vassals for reasons that make little sense.

They are a matriarchal society that wishes to test the strength and valor of their males against the virile males of the human race.

So they send their males down with slightly better gear than what humans have, and see if we crumble or overcome impossible odds, then we become the new breeding stock, our females become cuckqueens, and they search the stars for the next species to test US against.

>wanting human genocide NTR

>>54097351
>human genocide
Lets assume the alien space females have omni-compatible wombs that can create hybrids.

Actually, this is a cool idea for an alien species, make them a trifid like tentacle monster species that are essentially walking wombs collecting the best genetic material with which to make the best possible offspring. They can take from anything, so they could effectively breed their own subservient race out of animal material, but to pass on the mantle to the next generation they have to find a suitably intelligent, adaptive and tenacious species with which to breed.

Instead of an invasion from space, have an invasion through time. In the far future, post-FTL earth is winning a war against an alien civilization, so in an attempt to turn the tide, they use experimental time travel technology to send a small, well equipped force to wipe out the human race. The current time is the earliest they could send them back to, and their high tech but low numbers means the aliens must work with stealth.

>>54097414
I was just baiting, BTW. I just wanted to note how it's similar to NTR. I added "human genocide" because the humans are actively prevented from conventionally reproducing with each other.

Also, why wouldn't the aliens just clone the humans that won and fuck off from them (assuming all they want is genes and honor). Their technology would likely be advanced enough to have fully-functional cloning, or at least tissue growth and slaughter-free meat.

The aliens barely managed to get to the first habitable planet.
Earth.
They never had FTL, their planet was dying and they loaded as many as they could onto colony ships and fired them out into the void hoping for the best.

after thousands of standard solar years of drifting through space, the culture aboard the ship, their understanding of science, and even how their own tech works devolved until they are nothing more than warring savages with a handful that know the secrets of how to keep the ship barely functional.

They crash land here, with their only hope being conquest.

Retarded. Don't ever do this. It's one of the most hackneyed cliches ever.

>>54097423
Why didn't they just send a spacenuke back to blow up Earth?

>>54098622

Have you seen Terminator? Time travel doesn't work like that. Obviously, they had to grow a skin layer over their gear, and the few bombs they had left were too pointy and radioactive for that to work.

>>54097423
One idea I faintly remember is similar to this.Their FTL involves some amount of time travel, and is limited to being able land them on Earth at a certain year. Therefore the aliens are scattered over the course of the year with no way to guarantee that any particular asset will be there when they need it.

I liked the aliens from Iji.
For starters, they instantly obliterate most of the planet's surface with orbital strike, which is a sensible thing to do for any colonising alien force.
It also had one of the coolest pacifist/genocide run duality I saw in videogames.
Aliens are reasonable and they understand they act monstrous from a human's point of view, they do not pretend to be dindu nuffin, so both them and the game itself respect your desire to murder them all. On the other hand, when playing as a pacifist, you encounter more recurring characters willing to talk with you - and these are not some obviously special guys, just ordinary soldiers which you would kill otherwise, not knowing that they have some personality or personal motives.

>>54097530

>>54097414
>>54097509

In my setting, the aliens are refugees (not /pol/, I swear) trying to find a new world to settle after a coalition of alien nation stomped their shit in for being warmongering assholes. They don't have a whole lot of time or resources, so the invasion is poorly planned and they have to rely on captured human equipment to do most of the heavy lifting.They almost succeed, but eventually the alien coalition finds them and beats them up for the humans.

30 years on, humanity is uplifted and the invaders are playing District 9 in Australia.

Like others have said, you have to bring the aliens down to a manageable level. Bringing in an outside force to clean things up helps too.

I've been debating basing a game off of this for a while now.

https://en.wikipedia.org/wiki/The_Road_Not_Taken_(short_story)

tl:dr, aliens invade with 17th century tech, because our scientists missed the blindingly obvious FTL method the rest of the galaxy uses. Entire invasion force BTFO by the national guard.

>>54106106
Reading this was honestly kind of funny, human engineers figuratively smacking their heads dumbfounded that we had missed gravity manipulation because we were distracted by other pursuits.

Then humanity after conquering runs into another species even more advanced but without FTL...

The UFO After_ series had an interesting premise. Rather than the alien invasion being a full government of jackasses, the aliens had actually been trading and secretly talking with Earth's governments for decades. Then a bunch of space-terrorists stole some ships and a weird bio-weapon, jumped to the Sol system and blew the warp gate to hell. The game takes place as they are desperately trying to complete their devious scheme, before the intergalactic authorities can install a new door to kick in.

>>54106192
Nah.
There was a strife which divided the alien race into two different civilizations (and species, due to genetic engineering). One of them lost the resulting war and was destroyed almost entirely, their armies vanquished, their planets exploded. Only a small fleet with the last remains of their people managed to escape, while the adversary searched the galaxy for their traces. With nowhere to hide, they decide that there is one place where, with any luck, pursuers would not think of. The Origin. Home planet of both alien species, abandoned by them long ago. However, upon arriving, they see an entire new civilization thriving on a planet they left as a barren wasteland eons ago. They might try to establish contact with natives, but then they probably wouldn't be able to hide their presence on the planet in time, even if the natives were cooperative. Besides, the enemy would likely want to investigate the new intelligent specie and discover the refugees. Their commander decides they can't afford the risk and have to eliminate the traces of intelligent life here for the sake of their survival.
They are discovered anyway.
You should play it. It was great for a freeware game.

There is a Larry Niven novel called Footfall that is considered one of the best ones about alien invasion. There aliens called Flithp have several traits that make them defeatable and gives them a reason to invade:
1) they are not much more technologically advanced than humans. All their tech was conceived but not built by humans before. They are not defeated through absurdly fast reverse engineering or through being allergic to Earth. Instead they get hit by creative use of existing technology.
2) they don't understand their own technology as it was taken from precursor civivization
3) they are initially a colony mission
4) they expect humans to behave like them
The Fithp evolved from herd animals, unlike humans. They have a very alien idea of conflict resolution. When two herds meet, they fight until it was obvious which one was superior. Then everybody immediately stops fighting, and the inferior herd is peacefully incorporated into the superior tribe as second-class citizens. Fithp do not comprehend the concept of "diplomacy". So they show up and immediately attack something important like the middle of US with an intend to cause humans to surrender and then wait for the reply.

>>54095745
The aliens are a coalition from the future here to stomp out all earthlings before they become a tyrannical intergalactic empire.

They're humans from an alternate Earth that is only ahead in interdimensional portal technology, but at c.1960s for everything else.

They have amazing strategic mobility, and logistics, but that is it.

It's sad that even Niven, who's written some damn fine stories, succumbs to the Planet of Hats and Humanity Is Superior tropes. In retrospect his kzinti race is hilariously badly written, with less reasoning ability (about fights) than actual house cats. Even cats don't just "scream and leap" repeatedly at obviously superior foes.

Last RPG I played was Dogs in the Vineyard

Well... that would certainly be original. But to be fair I don't think even aliens would really give a fuck about 1850s' Utah.

Anyway I wouldn't do a full-fledged invasion.

Why? 'cause when imperialism didn't work that way. First they simply saw the land (and natives generally didn't grasp the problem breeding there), then maybe they came, but they generally didn't have any reasons to exterminate people. Either local manpower was a good thing, or superior technology meant no real armed resistance was a problem, or the land wasn't even that important in the first place. Invasions usually take a "militaristic" angle that doesn't make much sense (tough I guess something like Footfall makes sense).

Personally I'd consider different scenarioes. What if actually Earth is something like Japan in the 1800s, isolated and not really worth that much fuss over, the aliens are content with trade and shit cause there is so much worth more of their times, and decides in the end to play their game alright?

In general I don't think aliens would really like us to be exterminated. They wouldn't have much reasons to, unless they treat us as food or something.
Pic might be an interesting idea but pretty different. What if they see Earth, or us, like we see lions in the parks?

They're not a true invasion, they're the colony ships of a planet that was under threat of an extinction level event (think rogue planet was hitting their homeworld). They sent as many ships to as many planets that seemed habitable as they could in hopes of hitting a habitable one. One of these ships arrives at earth. They've got weapons, but they're not prepared for full-scale war, and can't just go somewhere else.

>>54095745
the first part of doing an alien invasion plot right is giving the aliens an actual reason to invade; the second, working in concert with the first, is creating limits and flaws the aliens will have to follow; the third, seemingly in contradiction with the second, is to not make the aliens act retardedly.

the best route in my eyes is to have aliens that invade to collect biological and genetic material en masse, not have them all too much more technologically advanced and to have their forces logistically restricted.
they will be sneaky, they will be diplomatic with some nations to avoid the forces of earth to unite and they will seize or destroy any weapon of mass destruction that could both be used against them and against the resources they are gathering; they may to enslave the world to milk its resources if possible but they will otherwise just leave when enough resources are harvested and scorch the earth to avoid any possible retaliation.
this is if you want an alien race that's still somewhat organised and not acting on desperation.

1.) Aliens utterly crush humanity; humanity is content living in the shadows and avoids angering the new top predator on the planet
>campaigns would be about surviving in a savage world with weird schizoid techno-barbarian tech levels, about big heroes trying to stop insane wankers trying to agitate the aliens
2.) Aliens utterly crush humanity; humanity continues to crush itself towards extinction against an invincible enemy
>campaigns would be about batshit insane plans, like nuclear suicide bombings, or fucking up the entire ecosystem of earth just to spite the aliens
3.) Aliens utterly crush humanity; post-singularity AI "recreates" "(in)humanity" designed to take on aliens
>campaigns would be like your typical superhero plot, perhaps with some more drama when the players found out they're not real people, fighting for a vengeful AI to avenge a long-extinct species
4.) A force let by a single alien or a small group of aliens crushes humanity (think a clone army, robot army, or mindcontrolled humans); but humanity might have a chance as it is just one entity/small group they have to fight

God, I hate the queen/mother/hive-brain bullseye trope, but I can't stop loving the images it ends up evoking.

why did everything need to get that much more shitty?

this is extremely stupid, why do you think it makes for a good plot?

>>54117039
Because it makes the humans the bad guys, and has some contact with aliens after their failure. It's like District 9.

but the humans in district 9 did nothing wrong

Right, sure. But in that comic's case, the aliens are understandable in their bitterness - they seem to treat themselves as a proud warrior race, the alien in question thought better of humans than most of his people, and he was treated cruelly and unlike the manner that he thought his people should be treated by anyone decent.

Hiding your evil behind the bureaucracy excuse is still evil.

Footfall

There is an alien invasion that threatens the whole globe. The nations of Earth, all working together against this foreign threat, manage to beat off the aliens. There is great celebration, rejoicing, and pride in their achievements, with excited ideas of learning from alien technology and the advancement of mankind into the stars. There is even a certain moral pride in that they were the righteous ones, that they offered every attempt at diplomacy and surrender to their foe, which fought to the bitter end.

And then there's another invasion only a few years later which has to be fought off, again with much blood and tears. And another. And another. Every few years, with enough variation so it's not quite predictable, there is another large invasion fleet that strains humanity to the breaking point, and never quite gives them enough time to lick their wounds and rebuild what was lost.

Eventually you get to the point where the latest generation of young soldiers are bitter and angry at the old generation, decrying those 'heroes' who didn't manage to beat the aliens properly - if they had, the aliens wouldn't keep coming back. This is the final straw that causes humanity to crack - they had united together out of necessity each time, but of course everyone chafed under this agreement, afraid of losing their culture and identity to this earthwide alliance and exhausted after years and years of war.

Start whatever you do with this setting in the midst of this state of civil war, with the Terran Defense Force in open rebellion against loyalist holdouts, and many countries warring with each other or desperately attempting to negotiate with the incoming aliens for parley. Even the areas that are still relatively peaceful are tense, and everyone is tired and despondent.

Reveal that this was the plan of a large alien empire that had sent the forces of its client-states against Earth to wear it out and make it easy to conquer. Do with that as you will.

... idols aside, wasn't the story of the first series about aliens wrecking the shit of humans and the SDF-1 trying to escape them?

Have the alien force be only a small mining expedition. The Scrin in Command and Conquer 3 lost because they expected humanity to be 90% extinct and incapable of resistance, so they only brought a very small force. Kane triggered a detonation of liquid Tiberium, something that usually only happens when a planet is 90% covered with Tiberium, to draw the Scrin to Earth prematurely, so that they would be defeated, and he could use one of their mining towers to teleport off of Earth, which he'd apparently been stuck on for six thousand years.

well, first thing you need to do is estabilish a believable motive for the invasion, dont be all like "they needs us for slaves", they spacefaring creatures and probably can build worker robots.

>They think that the other side just possesses an entire army of mages
We completely wipe them out and reverse engineer their technology
