Blueprints

Blueprints can be purchased at the Market with credits. They can be used to construct weapons, sentinels, warframes and orokin reactors and catalysts that are otherwise only available to purchase with platinum. The primary difference between buying a blueprint and the regular version of equipment is the time and resources required to acquire the in-game item. Some blueprints cannot be purchased. They have to be obtained through alert mission with a "?" in the reward bar.
