Side scrolling shooter (Shm'up) putting you in control battling rouge fishbots

The year is 2115, Earth has suffered catastrophic climate change and is now on it's knees. The seas have risen over 200 feet in 100 years and the best hope for earth resides in our oceans. But the Fishbots created to protect that ecosystem have malfunctioned or have been hacked as they have turned hostile killing that which they were supposed to protect.

Take control of your submarine and battle across 25+ levels of fishbots and fish-bosses. Customize your ship to be more effective and to match your playing style and find the main base where you can find out what has happened and how to stop the attacks. Through data logs found in various levels find the story behind the demise of earth, and see if there is a way to save the remaining human population.

Each Ocean has it's own enemies and style and as you get further in you'll find that the deeper levels are darker and require more thought as your field of vision changes and becomes more limited.
