After China declared that game companies must reveal information of in-game drop rates, the likes of Blizzard have made the information public. Now, Digital Extremes have followed suit and provided the drop rate information for Warframe.
The studio released the PC drop rate information prefixed with the caveat
This list represents data and drops from the PC version of the Free-to-play game Warframe. That’s right – Warframe is free! Which means our drop system is designed to maintain a balance. Our free players can earn the game’s content, and our paying players who support us with purchases usually get first dibs on the content by using Platinum (which can be traded to free players)!
There doesn’t appear to be an equivalent drop rate chart for PlayStation 4 and Xbox One or any confirmation that they align with the PC counterpart.
The full list of drop rates per item and category is quite extensive so if you want to know everything, check out the breakdown here.
Warframe is available now as a free-to-play game for PC, PlayStation 4 and Xbox One.
