Iona is the mental model of the submarine I401, one of the oldest mental models of the Sea Mist Fleet, and she has now arrived under the abyss of Europa.

Now she certifies you as the "captain" and hopes that you can meet crew members with different personalities and unique abilities during your free journey. With your crews, you can defeat strong enemies with them, retrieve the mother of the FakeFish that does not exist and gradually discover the truth of the "abyss of the ocean".

=============这里是 =W= 分割线=============

Conventional weapons include two automatic cannons two fragment cannons two electromagnetic railguns and two heavy cannons.

The ship has three proximity guns and three sets of automatic power grids. Expected sailing speed of 30km/h Expected vertical speed 16-14 (-20)

The ship has an automatic repair system (a solidified foam grenade with a battery tag, do not take it away!) and a ballast tank sterilization system (cleaning the ballast tank thalamus)

A tutorial from "大诗糖分糖"

1.The upper interface is not the exit hatch.The hangar is the real exit hatch instead. To exit the submarine from the top, you need to press the hangar door button. There are two buttons in total. One of them is in the hangar for mariner. Another one is in the command room below the periscope of drone control.

2.There is a periscope on the upper right cornner of navigation terminal. This one can control all the RailGuns and their coaxial cannons. It can switch up and down is automaticly. But you need to switch the type of guns on the switchboard below the periscope(or simply open the navigation terminal).

3.The gravity gun needs to be deployed on the navigator sonar minitor first, which is on the left side of the command room. The gravity gun cannot be fired when the charge is less than 95%.

4.The ballast tank disinfection function needs the ballast tank be emptied before the disinfection function is enabled. The thalamic root will be killed within 5 seconds generally.

5.If forced docking is enabled on the lower interface, the indicator under the console on the damage tube surface will turn red (the drone can be hung here, do not hang the drone in strange places at random!)

6.If the AI is stuck, please cure them with handcannon. This must be the pot(responsibility) of FakeFish. = =
