Metal Auger: Drop sources, locations, and probabilities

Tips

There are many ways to get Metal Auger in Warframe, but my recommendation for optimal efficiency would be to try one of these missions (in this order):

• Jupiter/The Ropalolyst : It's a Assassination mission (level 40-40). Probability to get it: 20.00%.
• Earth/Cambria : It's a Spy mission (level 2-4). The item is dropped on rotation C (10.00%).
• Venus/Unda : It's a Spy mission (level 4-6). The item is dropped on rotation C (10.00%).
• Mercury/Suisei : It's a Spy mission (level 8-10). The item is dropped on rotation C (10.00%).
• Mars/Arval : It's a Spy mission (level 9-11). The item is dropped on rotation C (10.00%).

These recommendations are based on the usual missions lengths, and the probability of getting the resource dropped.

Missions with a Chance to Get Metal Auger as a Reward

Warframe Rotations Explained

• Defense: One reward every 5 waves, following this pattern: AABC.
  So, rotation A reward at 5 and 10 waves, B after 15 waves and C for 20 waves.
  Then it starts all over again.
• Rush: Number of transports destroyed:
   - Rotation A: one.
   - Rotation B: two.
   - Rotation C: all three.
  
• Infested Salvage: One reward after each successful decryption, following this pattern: AABC.
  
• Spy: One rotation level gained per vault unlocked.
  First vault is rotation A, two vaults is rotation B, all three vaults unlocked is rotation C.
