In the Campaign mode, you will fight NPCs and liberate the occupied bases to receive rewards.
There are 3 levels for difficulty: Easy, Normal, and Hard.
Looting mechanism of the Multiplayer mode is not applicable to the Campaign mode. You only gain Clear rewards when you win a battle.
Clear rewards can be acquired repeatedly, even if the stage is cleared once.
However, First clear rewards can be claimed only once.
To play each stage required Gas. The gas consumed is half for multiplayer.
Just like in the Multiplayer mode, you gain war stars depending on the result of the battle in the Campaign mode. You also get campaign bonus gems depending on the accumulated number of war stars you acquire in the Campaign mode.
