Method 1: Sell Prime Warframes, Weapons, & Mods But, the truth is, if you’re a fan of the grind like me, you can still grind to earn Platinum in Warframe while doing in-game activities. This, of course, makes some people mad about the game. In addition, you can also use Platinum to buy new Warframes and mods without even having to finish some of the main missions. Warframe lets you buy lots of things using Platinum, including cosmetics for your Warframes and boosters for gathering resources much faster. Microtransactions are only for speeding up progress. Everything is accessible to free players. Platinum is the premium currency available in Warframe that you can buy with real money to purchase microtransactions in the game.īut, Warframe doesn’t lock content behind paywalls.
