JC-07 Scylla ft. Emma the Ship AI

Recommended experience level: Intermediate+
Recommended players: 4-10, Bot-friendly
For public servers I strongly advise to lock all wiring

It has a talking ship AI, you can set the frequency of random voice lines, have her on system messages only or turn her off completely if you had enough 😛

The Scylla, formerly a rugged if unimpressive multi-purpose submarine, then converted into a research vessel by an added moon pool and mech for cave floor operations, then fallen into the hands of smugglers who added extensive but haphazard upgrades as well as a small drone for dead drop recovery, creating the intricate, if perhaps not pretty, monster that it is currently named after. Her durable electrical system is now being used (or abused, however you like to put it) to drive her mediocre engine to new heights, though at not insubstantial risk, to outrun authorities (or even deadlier things) while still keeping a low profile.

***It is necessary to update the autoreactor when getting any upgrades that increase maximum reactor output. This is done via text command at the command terminal. For each 3% upgrade bought from stations add 240, if your engineer has the Buzzin’ talent (+10% output) add 800, with a maximum of 9520.***

There are 3 different power modes:
-Normal: Power is provided by the reactor and drops in voltage are compensated by the gap support battery, the large battery bank is disabled.
-Battery: The reactor is disabled, power is provided only by the large battery bank.
-Stealth: The reactor is disabled and maximum engine output is throttled by half to reduce noise generation to a minimum.

The command terminal offers options to configure parts of the ship, be it text display colors, door closing delay or voltage values.

The Mech has to use a jump jet to go upwards with a limited capacitor charge. When it’s empty you go upwards very slowly, but it can be recharged by hovering in place for a moment. Its "legs" are invulnerable to damage so you dont need to worry about collisions with the ground. It also comes with a built in RTG providing a small amount of battery charge while power is turned off. *Note: only open the outer door when stationary and on solid ground

The drone has a discharge coil with 3 uses which only get replenished while docked to the submarine.

Overvolting/Undervolting the reactor via buttons in the reactor room sets the target grid voltage to a percentage between 125%-175% and 90%-55% respectively (configurable in the command terminal). This is simply multiplied with the reactors perceived power demand. By changing grid voltage you multiply the output of engine, pumps, and fabrication by whatever the current grid voltage is. Overvolting yields more output, Undervolting saves power.

ÜBERDRIVE is a special mode in which the electrical grid is split into two units. Reactor, ballast pumps and engine in one, battery bank and the other ship systems in the other. It also sets target voltage to 199% (200% is when junction boxes take damage). While this will repeatedly do slight bursts of damage to your engine and ballast junction boxes, it also doubles your engine thrust and ballast pump speeds, as well as allowing it to actually reach nearly 2x voltage which is not possible while the reactor is powering the whole ship. Just remember to keep the pedal to the metal, if you stop your junction boxes will fry.

To other sub builders: feel free to take the modified sirens + sound files of Emma and include them in your own submarine, but please leave a link to this sub in your description.
