Warframe as a game is always changing and evolving. Two major examples that I have personally played through are the U22.12 weapon overhaul, and the U27.2 Warframe Revised update. Unfortunately for a sporadic content creator like myself, this means that my content is made redundant over time, and I don't have the time to update everything. As such, please take note of the version at the time of each review's latest update.
Pandero Prime is one of Octavia Prime's signature weapons, an MR14 Secondary. With very strong stats across the board, it is a solid, if fairly un-interesting, low-capacity hand cannon.
Octavia's signature secondary, the MR 8 Pandero was released in U20 alongside the Tenora. In the U22.12 Balance Pass, it was one of the few weapons to receive stat changes that weren't an overall buff. Nonetheless, it remains a powerful and fairly versatile pistol with a fun and mostly unique secondary fire.
