The initial price currently in effect will rise with the 1.5.3 patch scheduled for August 2019. If you haven't bought it yet, hurry up.

1. On the battle stage, the deployment of our fleet is divided into three lines
On 1st line, when the ship consumes all of its weapons energy, it automatically retracts to 2nd line and collects a certain amount of weapons energy, and then automatically advances to 1st line again.
If there is a ship in front of our ship, the ship in the back can quickly gather weapon energy. But at this point, the ship in the back is not allowed to use lasers.
The cargo ship will automatically retreat to the 3rd line at the start of the battle.
3rd line ships do not automatically advance 2nd or 1st line.

2. The Automatic Shooting button has now been switched off for a few seconds after use and then back on with a timer. It's not toggle anymore.
Also, turning off the automatic Shooting button will speed up the recovery of the entire fleet's weapons energy.

3. On the assembly screen, the correct weapons are automatically set in each weapon slot, reducing the effort to choose each weapon.

4. The Frigate has been added in addition to the built-in destroyer at the start of the game.

5. There are changes to the special resources used for skill upgrades As the number and type of special resources changed, some items decreased and some items increased.

6. The content of 'Tutorial' has been modified to explain the above.
