How to spend the 50 platinum? Can I get more?

Solution 1:

For most players, 50 plat is best spent on:

• 2 Warframe slots

  • 20p each, 40p total

  or

• 8 Weapon slots

  • 12p for 2, 48p total.

  or

• 1 Warframe slot

  • 20p each, 20p total

  AND

• 4 Weapon slots

  • 12p for 2, 24p total.

It all depends on what you'd like to get the most out of. Since there is a wide variety of guns in game some players opt for the weapon slots, while most others might opt for Warframe slots since those are your "classes" so to speak.

Solution 2:

The general best use for platinum is to unlock spots for storing warframes/weapons. You can get some free platinum from daily rolls if you get lucky. The other way to get platinum is to trade rare mods, prime blueprints, kubrow imprints and a few other things for it to other players. As of now there is no auction house, so you will need to find people in the Trading channel. See here for more info on trading.
