Description

Using an experimental vacuum reactor, the Yonaka's battery arrays can receive a constant, uninterrupted flow of power, allowing the sub to effectively never run out of fuel. While sporting an excellent array of weapons and over the top speed and manouverability for its class, extreme care must be taken in handling this sub, as the barely understood alien technology used for the reactor may cause significant issues if handled poorly.[/quote] [h1]Properties[/h1] [table] [tr] [td]Designation: [/td] [td]Tier III Attack (Low Profile Experimental Hunter-Killer)[/td] [/tr] [tr] [td]Cost: [/td] [td]22500 Marks[/td] [/tr] [tr] [td]Size: [/td] [td]55x14 m[/td] [/tr] [tr] [td]Recommended Crew Size: [/td] [td]6 - 8[/td] [/tr] [tr] [td]Cargo: [/td] [td]8 crates[/td] [/tr] [tr] [td]Armaments: [/td] [td]2 coilguns, 1 railgun, 1 chaingun, 1 hardpoint[/td] [/tr] [tr] [td]Mobility: [/td] [td]High[/td] [/tr] [tr] [td]Max Forward Speed: [/td] [td]36 Km/h[/td] [/tr] [tr] [td]Max Descent Speed: [/td] [td]17 Km/h[/td] [/tr] [tr] [td]Crafting Facilities: [/td] [td]Fabricator, Deconstructor, Medical fabricator[/td] [/tr] [/table] [h1]How to play[/h1] [quote] The alien reactor on board of the Yonaka is capable of a constant stream of power without the need for fuel rods; this makes the sub's autonomy effectively infinite, although the technology itself is barely understood as it is, resulting in a reduced overall performance and several side effects. For starters, as long as the battery charge is below 25%, the power flux is not stable and will periodically discharge dangerous electric currents on the hull; if the reactor comes into contact with water, the power flux will instead discharge INSIDE the submarine (regardless of battery charge), therefore any damage to the hull that could leak into the reactor should be fixed as fast as possible. In extreme cases, removing the battery may be necessary in order to avoid electrocuting half the crew, but it is possible to disable the reactor from command. Remember that electrical discharges will continue for a while even after stabilizing. With that said, the Yonaka has a full set of crafting facilities on board and a very powerful engine, making it extremely fast and manouverable for its size. However, the batteries that regulate the power flux can hold on for only so much, therefore the sub may require several stops in order to recharge and perform at peak capacity.

Author's notes

Would be interesting to see how Traitor mode works with this sub; there isn't really any sort of ID requirement for using stuff on the ship, so that may be something to work on for a future update.
