Hi there!
After 4 years, I decided to come back (maybe); I download the game and started playing a bit. I was confused, because the game changed a lot; also, after 3,5 years, I still haven't recieved my free Frost Prime from the Twitch Prime loot (from july 2017, and the warframe support didn't help unfortunately). Anyway, can someone help me to understand everything that changed? Like a video or a quick guide message, something idk.
Also, since I didn't receive Frost Prime (and I really want it, it's my favourite), can someone tell me if I can exchange warframes? Not the projects or
