A Colonist Shepard background?
Yup, her brother will be a part of the Torfan assault in the next story setting.
@Axle What does the Helghast have in term of combat force? I seriously struggle to think of a non-Zeus force that can hold back a combination of From the Depths and Factorio with Fallout and Mass Effect technology.
The Helghast empire are almost exactly on par with the Systems Alliance.
I'll break it down:
Homeworlds:
Earth went through a nuclear holocaust, leading to a hostile aftermath that made the people forced to survive. They adapted to the remnants of old technology around them, and have created something new as a result. Earth citizens have a sense of 'individualism', mixed with 'synergy,' believing they have to rely on one another to survive all adversaries.
Eden is a cold hostile planet with bug like monsters that make survival nearly impossible to survive... Yet they survived it anyway. Not only survive, but thrive. The UNSC tried to stop them from seceding, but failed. Helghast have a militaristic dictatorial government, similar to the Soviet Union. Although they originated and call Eden their homeworld, Vekta (a neighboring planet) has more people than on Eden.
In terms of planetary control:
The Helghast Empire found a Mass Relay near their solar system, and used it to colonize two dozen planets.
The Citadel Council contacted the UNSC. The UNSC chose not to join them, but the Systems Alliance (which represented earth) was newly founded, and Earth accepted membership in to the Citadel Council. The Citadel Council went out of their way to supply and help earthlings colonize other worlds, to use them as a 'shield' against space pirates and Helghast.
And now Helghast and Systems Alliance are equally at each other's throats, doing everything to counter each other. From blockades, to terrorism. Assassination, to bombings. Its hostile when colonies are boardering each other.
Technology
Main military: The Sytems Alliance are nothing compared to Helghast main forces. Helghast citizens are raised up at soldiers since birth. Systems Alliance often uses local communities to train soldiers, meaning someone from China might have more training than someone from New Zealand. While some Systems Alliance soldiers are exceptional
, all Helghast soldiers are exceptional. The military culture makes Helgahst troops the most relentless group of soldiers among humans.
Laser Weapons:
Standard Earthling soldiers has laser weapons (which can pass kinetic shields), but the UNSC and the rest of the Citadel Council don't (Specters use them, but it's considered a military secret). Earth has these weapons because it was rediscovered following the Nuclear Holocaust ruins.
Helghast have laser weapons too. Akrid (monsters from Lost Planet) are unique to their homeworld of Eden. They harness the natural energy of these animals, and use them to create laser weapons. Different design, same effect.
Mechs:
Ironically, there are corporations than sell parts and schematics of mechs to both sides. There will often be two mechs of the same design fighting each other, so mechs are precisely equal. (Thin Titanfall)
Drugs:
Systems Alliance soldiers commonly use vigor (from bioshock infinite) to give them a bonus strength.
Helghast soldiers used Plasmids from the original bioshock game.
The key difference between these drugs is that Vigors are non-addictive, yet weaker. Plasmids are highly addictive, and more powerful. The Helghast use these drugs to control their soldiers, and keep them dependent on the government. So Helghast drugs beat Systems Alliance drugs.
Helghast will genocide Conduits
The Helghast empire bans Conduits. They genocide them out of fear that they might gain too much influence.
Systems Alliance welcome Conduits, and utilize them efficiently.
Systems Alliance have more cyborgs than Helghast:
Helghast homelands on Eden is a mostly cold, and makes maintenance of machines more difficult.
Remember the rule:
One cannot used plasmids or Vigors if they are cyborgs, the drugs cause the cybernetic parts to fail.
Therefore, while Helghast soldiers commonly use plasmids to exert control, they also limit the amount of cyborgs and reploids they have (typically government officials use them, but not foot and frontline soldiers). Systems Alliance has a more diverse usage of robots than the Helghast do.
Ship sizes:
Their fleets are almost the same size, and neither side are willing to sacrifice the bulk of their space navy for a full-on confrontation. Think of the Systems Alliance fleet size in Mass Effect 1, matching itself.
Speciel forces:
Systems Alliance has the Tenno Branch, an elite force using ancient alien armors called "warframes". These soldiers can single-handedly defeat armies, but they are extremely rare. Although its rumored to be at around 300 soldiers, its actually much smaller and the true number is kept secret to boost morale.
Helghast don't have a Spartan program yet, because they aren't efficient in cybernetic parts (I would say each soldier equates to a Halo Noble). BUT, the UNSC is working on a program to have people use augmentations+Plasmids. If it succedes, the Helghast Empire would have the chance to steal that intel, and implement it into their entire population to have all their people as strong as Spartans. (This hasn't happened yet, but there's a chance they'll try it)
Mercenaries:
Of course, everyone loves hiring mercenaries. The key differences is who hires who. And although there are many mercenaries that work with both sides, there are some exclusive mercenaries that both factions use.
Systems Alliance ask for the Jedi Order for aid, and the Helghast often have Sith lords working with them. Both these factions number at less than 100 members, but they have been known to change the tide of battles.
