The new shooting game called Audiostrike is out.
Idea is simple, imagine a standard shooter where you are choosing a ship and use left / right to move and shoot button but it's more advanced. You have bonuses, ships ubgrades, you need to avoid bullets and as far as I know there are unlockables.
The game is translated in to english by Yukio as far as I know so you can play without any problems.
