Frames are starting to flow in now lol.
I started with Loki - then built Trinity (which is now my main more or less). Trinity is devastating in certain situations. Loki was interesting for a while but got super boring.
Next up in queue is Valkyr, from there I apparently gathered enough parts for Nova and Ember.
Out of the original 200 plat given, I've spent 24 for inventory slots, looks like I'll be on the hook for 40 more for two more Frame slots in about a week.
I'm running into a wall though - most players are either not pushing out to all the further out planets or it's just super hard to find people playing on those planets when I play.
Edit - personal to do list :
Finish Paris Prime
Get an Energy Siphon somehow from one of the Alerts.
