Examine the spy message logs in your terminal on the right. Decrypt your team's code and spend movement points (MP) to relocate the ship away from danger.

The fleet is in firing position. Select exactly one opposing squadron and designate your shell impact coordinates.

Commander has authorized system decryptions. Assess the results and update your physical boards.

Each point spent allows you to move one ship for one step along connected lines on your physical board. You can select 0 to save points. Unspent points carry over.
