Past alerts should be brought back somehow

[(PSN)apashby]

There are a ton of gaps in the story of warframe that you need to go on the Internet to find.

Why are the Grineer and Corpus at each other's throats

Why does Tyl Regor want justice for his 'tube men', whatever they are

Who is Frohd Bek

What is Project Tethra

Where did the fomorians come from

Stuff like that is answered by the events players did in the past that you can't do anymore, so now players are confused about all that and there is little to no explanation in-game.

I have two possible solutions in mind

1. Bring them back as quests/story missions (as a side note there should be restrictions to certain nodes that spoil story aspects, e.g. Bringing a noob straight to the moon to fight sentients before they do the Natah quest)

2. Give details about them in the codex listed under "past operations" or something, they could be unlocked by progressing through the story too

I would go with the second option. There should be some kind of a story journal, like maybe in Guild Wars 2.

 Have thought about this problem a few times, would love if they relaunched events. Sick of the 0's in my stats; would also let clans get a chance for the trophies

Things like that should definitely appear in the Codex.

In some ways it is cool that things happened in the 'past' in the game unlike some MMOs where the storyline is frozen in time but, as you say as a new player (of which I am one) there are large sections of the storyline that are actually now unavailable to consume in game.

Put them in quests, or add them to the simulacrum.
