If you have the latest device, it is possible to play the powerful space war game with high-definition (HD) images. While commanding a space fleet, aim for the annihilation of the enemy fleet and hold supremacy in the galaxy. While assessing the war situation, select the formation and direct the attack on the enemy fleet. Also supporting online matches, divide into two forces (federation and empire), and with the galaxy as your stage you can compete for power. Federation battleships and empire battleships each have their own features. With the ingenuity of each other as weapons, one can compete with global rivals for strategy and tactics. Fleet battles, combined with a real-time system and a command-type turn system, are semi-RTS. Instant decisions about such things as the timing of attacks will determine victory or defeat. It is possible to enjoy a sense of urgency just like one was actually commanding a fleet war battlefield. As one has more victories, it is possible to get more powerful space battleships. Discover your own way to organize the strongest space fleet, and your own way of fighting.

Optimal for playing during a commute, etc. For mission bosses, such things are large fortresses, large bases, and the strongest large battleships are ready and waiting. - Features - (1) Breathtaking 3D action all in real time (2) Visual effect controls to match the specifications of your device (3) Awe-inspiring sound powered by the 3D audio system [OpenAL] (4) Quick battles that develop rapidly (One battle will last approximately 1 minute).
