Description:

Once a spaceship that was considered junk, now, a submarine. A relic of the past that was in many peoples hands, even pirates. Slowly gaining features and evolved into a combat submarine. Perfect and reliable, with cool green interface and an interesting terminal. People often mistake it with the Humpback, i wonder why.

Lights update. (12/04/2024)

Now the emergency lights are off when there is power, when the power goes out, the emergency lights will automatically turn on. All that is the work of the junction box #5, if that box dies, all the lights of the sub will turn off, even of the turrets. You can always change it if you don't like that mechanic in the game on the circuit box over the reactor.

Price: 24000

Class: Attack

Tier: 3

Have:

Fabricator. Deconstructor. Medical fabrication. A lot of storage space. 2 Crate shelves. 2 Big turrets. 2 Small turrets. 2 Depth charge tubes and loaders. Front discharge coils. 2 Docking spots, up and bottom.

Features:

Automatic discharge coils that you can turn on and off. Better airlock, you can also exit thru the bottom, but thats an one way exit. Terminal that turns on of off the batteries, and can do other stuff ;) The captain have extra info in his room, can close the door to his room and can turn all the lights of the sub off. You can turn off the oxygen generator and the engine, don't ask why. Item transfer sistem from outside the sub to inside. Sonar and enemy detector monitor in the gunnery compartment. A cool drone. Mineral scanner. There is no automatic doors that open by themselves, i hate them. [spoiler]Self destruct system.[/spoiler]

Drone manual. (You can always reaseytderyhsdfhsdfad it on the sub.)

In this manual we will explain to how operate the drone.

--The drone have 2 modes, movement mode and attack mode. To change between the modes you need to double-click the left mouse button. When changing modes the drone changes the light color around him, red is attack mode and blue the movement mode.

--Hold left mouse button in the movement mode to move the drone. The drone can carry 1 crate on him.

--Hold left mouse button in the attack mode to charge and fire a laser. The drone only caries 2 shots by default, and you have a delay after a shot to shoot again.

NOTE: THE IMAGES I SHOW OF THE SUB MAY NOT BE ACCURATE, THINGS MAY BE A LITTLE DIFFERENT, BUT THE POINT STEEL THE SAME. I'M STILL WORKING ON IT AND IMPROVING THINGS. YOU CAN ALWAYS HELP ME OUT BY SUGGESTING YOUR IDEAS IN THE COMMENTS.

FOR NOW, THE SUB IS COMPLETELY PLAYABLE AND DONT SUPPOSE TO HAVE ANY BUGS, THE BOTS WORK FINE.

AND YES, TECHNICALLY IS A HUMPBACK, BUT ALSO NO. I LIKE THE FORM OF HUMPBACK, SO ALL I DID IS TAKE SOME BASIC SHAPES, THE REST IS A COMPLETELY NEW SUB.
