While playing Warframe, you’ll encounter a lot of these guys. The cloned, scrappy, heavily-weaponized Grineer and the shiny, money-loving, robot-abusing Corpus. There’s the Infested and the Orokin/Void as well, but they’re… not really the main threats right now. The Corpus and the Grineer are the ones already controlling huge swathes of the Origin System (i.e. our solar system), and they’re really the ones who have the most say when it comes to, well, existence.
Let’s start off with the Grineer. We know way more about these guys than we do the Corpus. The Grineer are the first people who find you, before the Lotus guides you to freedom. Basically, the Grineer are a gigantic army of clones, led by the Twin Queens. And they hate anything and anyone who isn’t Grineer. They’ve been expanding across the solar system and the only things that are stopping them are the Corpus, the Infested and us Tenno. If it wasn’t for the fact that the Grineer aren’t that good at cloning and they very quickly degrade, they probably would have overrun the system already.
That’s not to say that all Grineer are evil. There’s the Steel Meridian, made up of former Grineer soldiers, who wish to protect whatever it is the Grineer are currently trying to destroy. But the vast majority of Grineer are cloned, trained and brainwashed into wholeheartedly serving the Queens and could not give a shit if they just blew up a bunch of Tenno, demolished a Corpus ship or slaughtered a village of innocent humans on Mars.
On the flip side, the Corpus don’t really care about anything either. All they care about is making as much profit as possible, and to heck with the consequences. The Corpus aren’t really interested in the domination of destruction of everything, after all, they need people to trade with, but what they really want is to capture and re-purpose anything Orokin – including our beloved Warframes.
But the Corpus are much more willing to compromise than the Grineer, and are even willing to work alongside the Tenno. The first non-Lotus person to assist you is Darvo, a former high-ranking Corpus guy who now works solo, who you rescue and free, but even people like Alad V, a Corpus madman who captures Warframes and experiments on them and has been defeated numerous times, is willing to put his differences aside for a moment. Of course, all Corpus are looking to make profit, but at least there is a way to work with and around them.
To put it another way, you can convince the Corpus to not blow up a village, but you ain’t stopping the Grineer unless you get there before them and defend the village yourselves. Unfortunately, if the Infested or the Corrupted remains of the Orokin Towers decided to attack said village, you’d probably have no choice but to kill everyone anyway, due to the irreversible mind control and infection they both have.
But the Grineer have benefits in other ways. They have way more character development and have been way more involved in the world of Warframe than the Corpus have. Alright, most of that is negative, what with the destruction of the Relays, the Tenno hangout spots, accidentally uncovering a Sentient or two, and trying to capture Tenno so that their Queens destroy their minds and steal their bodies. The most character development the Corpus have are Alad V and Darvo’s daddy issues. The only other bonus is that, since Grineer are homicidal, maniacal clones, you don’t feel so bad killing them.
Really though, if all these Corpus and Grineer soldiers didn’t want to be killed, they wouldn’t fire first. At the end of the day, both sides will shoot you on sight.
Question is, there aren’t really any better alternatives. The Infested are horrible, malformed, infected beings that moan around in pain. The Orokin were horrible and what remains of them is equally as horrible. And who wants to be ruled by a bunch of annoying teenagers in metal death suits?
Certainly not me.
