T2 - Meticulously crafted vertical mothership, with gravity elevators, a cave-exploring combat shuttle and an interesting playstyle. Upgrade of the Mothership (Bare).

Unique Features:

Features and Upgrades:

  • Fully Vanilla.
  • Bot friendly - Nearly perfect waypoint optimisation and design.

  • Upgraded guns: Top right Coilgun is now a Double Coilgun. Bottom right switchable Coilgun/Laser is now switchable Double Coilgun/Railgun.

Playstyle:

This ship is really enjoyable with people, but it has been designed with absolute care so that it can be enjoyed even in solo play, despite the size and complexity. It is a straight upgrade of the Mothership (Bare), which is the not-fully-built version of this. While the Mothership (Core) is not yet at its full potential, it is now a very capable model. This version moves faster than the Mothership (Bare), shoots harder and for longer, it also has some discharge coils to protect the bottom airlock and the very top hatch. It can be further upgraded to T3, by buying the 'Mothership'.

Overall, this ship should be very capable on vanilla, and somewhat difficult with mods such as Barotraumatic.

Model series: Mothership (Bare) -> Mothership (Core) -> Mothership.

Important Notes:

This model, like its T1 counterpart, is still prone to overvolting. Try to not go from 100% engine power to 0% suddenly.

The Magic Elevators will deactivate themselves if they contain water, or if someone is loitering at their very top. This is to avoid bots getting stuck in them indefinitely.

Known Issues:

Item Finder - Pings are too small Because of how Barotrauma works, the red pings on the item finder will be very small. Please use a fine eye and try to zoom in.

Status monitor - Rooms too small Because of how large the ship is, the status monitor linked to the sonar is not very useful. If you want to accurately see where your breaches are, close the sonar, and use the status monitor on its own. It's the monitor just left to the navigation terminal, it has grid power and fuel numbers on it.

Bot AI and the magic elevator There should be no more bugs as such, as this ship was designed, developed and tested over three intense months. However, bot AI will always do everything possible to mess things up, so you might occasionally see some bots going up and down ladders, because they decided that's a good spot to idle on.

Feel free to leave a comment Please do leave a comment if you find a bug. Hundreds and hundreds of small bugs were found while developing this, and ironed along the way. It feels surreal using the ship now and not finding any more. This ship bent Barotrauma so out of shape, for how the game is supposed to work, that it's incredible it works at all.

Host Dedicated Storage: How to regenerate ID cards

You will find these commands also ingame, on a hidden terminal next to the storage, which resides under the navigation terminal. But they can't be copied there.

Prerequisites: CORRECTLY installed Lua for Barotruama. See their workshop page for the installation procedure.

While wearing an ID card, run this command in the console:

SINGLE PLAYER: [spoiler] cl_lua Character.Controlled.Inventory.GetItemInLimbSlot(InvSlotType.Card).AddTag('id_server_host') [/spoiler]

MULTI PLAYER: Replace 'Name' with your character name, example lua yourcharachtername='John Smith' [spoiler]
