Space Attack: Power Invasion app for iPhone and iPad

Story:
After years of research and effort, humans have finally discovered a good enough fuel source that is within their reach, on a small newly discovered planet named Gradis. its been decades since Earth was out of all organic fuel, humans dug every place that could possibly have oil reservoir to the point that looking for fuel was no longer efficient anymore. now its 2062 and Humans needed what scientists called "CT-52", short for "Cosmic Trace-52" but it is commonly known as "CTrace" or "Citrus", NASA started a space program to mine the resource from the planet it was first brought from, but the mission was a failure due to an attack of unidentified flying ships which slowly overheated the drones to the point that citrus on the ship underwent a chain reaction, exploding the drones before they could return. they seem to be planning and preparing for a space war and we need the resources to protect the human kind.

You are hired to make sure extraction drones reaches back at base safely, using the highly advanced "IAD-18", which is galaxys lethal battleship known. Equipped with multiple blasters, Freeze Explosion and even overloading itself, creating a massive wave of molten plasma, using up all the power core charge in process. power core is what powers the ships functionalities and arsenal, it keeps generating and storing power for use, make sure to use the stored power efficiently. IAD-18 is capable of being integrated with Alien Upgrade Processors which can be found during battles and then used to upgrade the ship functionalities.
