Reclaiming Earth from a Xenomorph infestation (RAR)

[Borgholio]

Taking place after Alien 3, Weyland Yutani finally succeeded in bringing an alien to Earth where it promptly escaped and multiplied. Earth is completely overrun and billions are dead. You are given command of forces from any ONE sci-fi universe that you know of to reclaim the Earth and exterminate the Xenomorphs. You can choose any ONE universe and any tech from that universe that you want, but Earth must remain intact and inhabitable when you're done. No disintegration. (Sorry, channeling my inner Vader there).

Which universe do you choose to pull resources and tech from? Which tech or resources do you choose? What tactics do you use to reclaim the Earth and exterminate every single Xenomorph on the planet?

Ask the Doctor for help, take the Tardis, go to LV 426 before the Nostromo showed up and blow up the derelict

Edit: oh and also publicly expose weyland-yutani via revealing the Nostromo's orders.

Well, that would certainly do that.

ASIDE from the obvious (except to me...duh...) loophole of time travel. What would you do?

[Tribble]

Umm, I dunno, take tech from some universe like star trek which allows me to develop bio weapons that can wipe them out, then deploy said bio weapons and wait for the dust to settle? You might have pockets of survivors that need to be moped up, but there would be little reason to go to the surface before then. It'd also seem rather fitting if xenomorphs were taken out by bio weapons

Xenomorphs aren't actually that dangerous an enemy, which is probably why the movies they're in always pits them against a handful of unprepared, unequipped civilians. The one time they go up against real soldiers, they are purposefully handicapped by a villain and a general lack of intelligence.

Literally any sci-fi universe could field a solution. Even Star Trek could probably pull it off just by operating fleets taking shifts beaming Xenos into active volcanos all day and shooting hardened nests from space.

One Company of Adeptus Astartes. Xenomorphs are nothing but a minor gaunt species, and not a particularly dangerous one at that. First Company Tyrannic War Veterans would wipe the floor with them, easy. Acid blood is nothing much to challenge power armour. Queens would be a minor difficulty, but they're not that much bigger than a Carnifex or a Hive Tyrant, both of which would be easily eradicated.

Alternatively, Solar Tempestus Auxila, full carapace armour, tank and artillery regiments, and a couple of Titan Legions with accompanying Skitarii. Point them in the right direction and command 'purge'.

Starcraft Terran Marines. Zerg are slightly worse than Xenos.

But, you know, if you have access to another universe, and the human population of Earth has been almost eradicated by xenos... why bother? Just find your fortunes elsewhere.

Can they kill the Xenomorphs faster than they reproduce ?

[Tribble]

Well, IMO the Xenomorphs were only truly effective due to the scenarios in the films:

Alien: Civilian crew with no knowledge on Xenomorphs. The crew was armed, but they were worried that firing on the Xenomorph would cause the acid to spray all over the place and potentially destroy the ship. Also, the Nostromo's sensors were damaged during the landing and Dallas decided to take off before they were repaired. This was ultimately the fatal mistake because if they had they been able to keep tabs on the Xenomorph at all times they probably would have stopped it before it was big enough to start killing.

Aliens: Heavily outnumbered Marines being led by an inexperienced commander. Like the Nostromo they weren't supposed to use their main weapons due to the risk of damaging the colony's reactor (and when a couple did use their weapons they damaged the reactor badly enough to cause a meltdown). Also, while the Xenomophs were able to hide from the sensors on this occasion thatwas because they didn't move until the last moment and the ambient temperature around the reactor made thermal tracking useless. It didn't help that the colony apparently had no sensors or cameras of its own. And that the Marines essentially ignored Ripley's warnings about the danger they were getting into.

Alien 3: Unarmed prisoners in an abandoned prison. Again with no known sensors. Ya, the Xenomorph was going to go on a feeding frenzy here.

Alien Resurrection: The Xenomorphs escape due to the crew's deep personal stupidity, like forgetting to acid-proof a container that's holding hostile aliens primarily composed of acid. Or having lethal weapons to quickly kill the Xenomorphs if a breakout is imminent. The crew also quickly panicked and abandoned ship, even though a co-ordinated effort probably would have contained the situation. We only really get to see Ripley and Co. as they tried to escape, and once again they didn't have access to most of the ship's systems.

If Xenomorphs are able to be effectively tracked, their threat level would be much reduced as their main successes usually were the result of them surprising and ambushing their victims.

Well, this presumes the xenomorph take over isn't a fixed point in time. Of course, as much as I love the show, Doctor Who is so inconsistent that its almost worthless to try to debate/analyze it.

Me... I think the Doctor has some promise, but all things considered, I'll go for Star Wars or Star Trek. Advanced, versatile series that I'm familiar with, without the loose canon factor the Doctor has.

For Star Wars, the obvious appeal is Force users to track the stealthy xenomorphs and mass produced non-impregnable battle droids. Plus limited orbital bombardment for any really big concentrations.

For Star Trek, its advanced sensors and medical tech. (I'm curious as to weather Federation doctors could save someone nabbed by a face hugger), plus transporters and wide beam stun phasers to take out swarms of xenomorphs while limiting collateral damage (though xenomorphs are tough enough that I don't know if that would work).

Oh, and the Federation is used to dealing with bizarre aliens and even negotiating with them. I wonder if xenomorphs are intelligent enough to understand the concepts of "parley" and "ceasefire".

If using a Star Wars team, I think I'd use several Acclamators loaded with separatist super battle droids and more elite models, plus droid scouts. Force users in command.

For Trek, multiple Galaxy or Sovereign classes. Away teams will be instructed to wear body armour for a change.

[Tribble]

Well if the time travel couldn't work due to plot devices, you could still use things like transporters. We've seen entire armies and even planets transported before on Doctor WHo, so it wouldn't be much of a stretch to take those devices, reconfigure them to lock onto all the Xenomorphs on Earth and beam them all at once into the Sun.

[The Romulan Republic]

Once you bring in Time Lord tech., you're only a small step away from bringing in the Q, when you get down to it.

[bilateralrope]

What would The Culture do about the Xenomorphs in this scenario ?

They can easily wipe out the Xenomoprhs if they want to. But would they want to ?

[Purple]

Any universe at all? Alright, I'll take a single warship worth of Daleks. Brutally efficient and destructive they have shown time and time again that not only are they capable of destroying any force that threatens them but they can achieve this with minimal collateral damage and a glee rarely seen in those that practice war.

[The Romulan Republic]

How exactly are you planning to control the Daleks to keep them from slaughtering all the humans too?

[Purple]

I was operating under the assumption that any forces we recruit are going to actually be obedient to us. Also that there would not be any humans left by the time the planet was overrun by aliens.

[The Romulan Republic]

Both uncertain.

In any case, even if Earth is all xenomorph, the Daleks would take it over and start expanding out.

[Purple]

Both uncertain.

Why didn't you bring that up sooner? I doubt a squad of space marines or any of the other stuff people mentioned would obey much better.

I didn't create the thread. Its not my job to spell out the terms of the scenario. If they weren't clear, that's either the OP's fault or your's.

[Elheru Aran]

It struck me that in the distant possibility of survivors, having 'boots on the ground' would be a better way of managing to rescue them than a full-out planet-burn.

[The Romulan Republic]

The OP specifically says that blasting the entire planet is not an option.

Hence the appeal of Star Wars' mass-produced, unfacehuggerable battle droids.

Edit: Its also a reason to have severe reservations about using Daleks, because for Daleks, collateral damage isn't a problem. Its the objective.

Really? I have newer once seen them blow stuff up massively. They just tend to fly around surgically disintegrating any people in their way.

[The Romulan Republic]

Really?

They were heavily bombarding Gallifrey in Day of the Doctor.

They blew up a planet (one of their own, no less) in Asylum of the Daleks.

Weren't both of those instances situations of extreme circumstances (as in fighting their arch enemy)? 99% of the cases we see them in the show they do not behave in such ways. Although my experience is limited to the new series. They might well have been worse in the original.

[Tribble]

There is no real reason to send ground forces unless there are survivors that need to be protected. And even then, that's only if your using a universe were transporters are unavailable, so you have to physically go in there to recue them. It should be noted that there is no requirement to rescue anyone according to the OP, only that the planet remain habitable afterwards.

Pretty much anyone who has transporters and/or the ability to fire weapons from orbit which can specifically target the xenomorphs will do.

Of course, an orbital solution would be boring, and it would be fun to watch Xenomorphs duke it out with things like battle-droids, terminators Daleks etc. I wonder who would win in a fight: a face-hugger or an unarmoured Dalek? We've seen Daleks strangle people before. Could a Dalek use its absorption ability from "Daleks in Manhatten" on an Xenomorph?

[The Romulan Republic]

A Dalek xenomorph hybrid? Good God.

Well, I'm torn between Star Wars for the effectiveness of its ground troops and Star Trek for the transporters, sensors, and medical tech.
