Black Market keys are given to all commanders who take active part in battles but the number of keys depends on the position taken:
In Domination, Beacon Rush, and Team Deathmatch:
|1||5 keys||4 keys|
|2||4 keys||3 keys|
|3||3 keys||2 keys|
|4||2 keys||1 key|
|5||2 keys||1 key|
|6||2 keys||1 keys|
Additionally, you can get Black Market keys:
- as a reward in Operations;
- as a reward on the Black Market;
- by completing clan tasks (for B+ rank clans);
- by purchasing them directly through the in-game store.
To increase your Black Market keys income from battles use special boosters.
