I see it’s free to play, do you ever need to spend money on it?
Too unlock storage space for war frames you need to spend money. I think you get three spaces for free so it gives you loads of time to see if you like the game. Plus you get log in rewards and I got a couple of 75% off vouchers that I used to buy a premeium warframe. Overall I probably spent about 30 bucks on the game and it was my second most played game this year.
