should we just keep doing the missions as they open? or should we do something special

Continue doing missons, do alert for cards/warframes. As you level your weapons upgrade with cards.

whats alert?

Alerts are randomly generated and can give you almost any item, they are on random planets and random moons.


The link below is the link that shows only the ones that will give blue prints

should i buy weapons and warframe blueprints with credits? or can i find them from drops randomly

I would not recommend buying the weapons out of shop, as they are overpriced, blue prints you can buy.


What I meant by it drops bp is, they drop their ( sytems,helmet,chasis ) not their actual blue print!
