There are 3 types of Missions.
"Main Missions", "Backup Missions", and "Single Missions". You will find an explanation about each type of Mission here.
Main missions are important storyline Missions in which you need to fight against the common enemy of all Commanders: the Chaos Army.
To clear a Mission, you have to find the location of the Boss and defeat him.
The further you advance, the more ferocious the Chaos Army opposition will be. Bring back peace to the galaxy by cooperating with other Commanders!
Many rewards received for completing a Main Mission cannot be obtained anywhere else.
In a Main Mission, the battle takes place on a map that is renewed every two hours.
This is called a "Phase".
In order to deploy Squads, you need EN points. EN is supplied every time a new Phase starts.
Use your EN to dispatch Squads and capture the enemy strongholds!
The "Progress Rank" is a representation of the game's current state.
If your Mission progress is above average, then your Progress Rank indicator will light up.
The higher your Progress Rank, the rarer the items you will be able to receive as rewards will be.
If you manage to fill your Progress Rank indicator to maximum level, you will gain access to EX Missions in which it is possible to obtain very rare items.
Sending a Squad to help another player's Main Mission is known as a Backup Mission. You may send one Squad to each available Backup Mission, for which you will be rewarded.
Backup Missions automatically appear on your Mission selection screen, but Backup Missions for players registered to your Group will be more likely to appear.
Priority Backup Missions
It is possible to send immediate aid to your own Group members by checking the box on their profile screen.
This will cause checked players' Missions to always appear in your Backup Mission list.
Check members with whom you want to become friends, or whom you want to assist during difficult Missions.
The limit of members that can be checked increases proportionately to the number members in your Group.
Unlike Main Missions that take place on a battlefield renewed every two hours, a Single Mission is a Mission that you can start whenever you want.
Single Missions also have a limited number of Phases in which they must be completed.
In order to clear a Single Mission, you must meet its victory conditions, much like with Main Missions.
Giving up and ranking down
Like with Main Missions, the more you clear Single Missions, the harder they will get.
If you feel that you won't be able to clear a Mission, you may forfeit and retreat.
By clicking the "Give Up" button on the bottom right during a Mission, you will be able to choose between starting over again from the first Phase, or lowering the difficulty level of the Mission.
