Holy shit you are stupid. There was nothing difficult about it. I failed it 3 times with 1-3 seconds remaining because of shitty life support drops.
Oh wait, I get it now. You're one of those people who think that there's some skill involved in Warframe's gameplay.
You don't get it at all. I neither stated nor implied that Warframe is a skill-intensive game, because it isn't. It's a mindless horde shoot-em-up game, and objectively, it's a pretty bad game. However, there is a major and very noticeable difference between competent players and incompetent ones; and there is skill involved in advanced parkour with a fairly high skill ceiling, although this barely affects actual game progression anymore. That's all beside the point, though.
The life support/enemy limitation during that alert is part of the "puzzle" and is fully intentional. Check the Warframe forums, and you'll see other people crying that it's incompletable and DE fucked up somehow; meanwhile, some teenagers figured it out and finished it in their first try.
"Git gud" = figure out what needs to be done instead of complaining about it and blaming the game/developers. Criticizing the game's design is one thing, but bitching because you failed is just whining. You might not like the way they implemented the alert, but they didn't fuck it up by any means.
