I've tried it a good year or so back, maybe even more, but from what I recal there wasnt much to go around and the Servers were very unstable.
Im curious tough, how does the whole Warframe thing work? Can you unlock different guys by playing, or do you have to buy them? I've watched a few Vids and there seems to be a lot of variation when it comes to the Frames and their equipment. I'd actually be interested to try it sometime.
I'm gonna go ahead and explain this too, because I thiiink it's gotten more convinient since Neovnivek played. It really did used to be a ton worse.
You buy the blueprint (few thousand credits, not that hard to come by anymore with invasions and tower keys), fight a boss (kinda grindy, but it's improved VASTLY from the past as a BP drop is now guarenteed, can take as little as an hour, maybe less if you're quick and have a good team) several times to get Blueprints for all the warframe parts (helmet, chassis, systems), spend resources and money to build the parts, wait for them to finish, spend the parts, an orokin cell, and about 30k credits (again, that's like three invasions/orokin tower keys, a good deal more significant, but not really a "farm all week" situation these days), wait 3 days, done.
The game very much operates on a pay for convinience (and cosmetics) model, but almost everything (if not everything) is available in game for free, you just have to grind for it. Cosmetics are Pay only, but honestly the starting pallette and the holiday palettes you'll accumulate over time are nice.
So is the genetic elitism a real theme of the game or is it something that the game is oblivious to
I think you're referring to the grineer, in which case, yes, the grineer are intensely xenophobic on a "enslave other races" level, and are clones of clones of clones, and as a result have decayed, and need big full body suit things to do anything. This is why heavy units are so huge, also why they're all wrinkly. The plot is addressing it more lately, but as of now warframe's plot is mostly an "out of game research" sorta thing, so you don't really see a ton of it in game. Mostly in boss dialogue in special event missions/assassination missions.
