Currently, Reassembly do not support multiple core per faction. So you have to use some "trick" to build ships with different cores. Reassembler have 3 different cores:

- The default nonagonal shaped small core with TELEPORT feature.
- The new heavy, medium sized COMMAND shaped core with TELEPORT and TORQUER features.
- A super heavy SQUARE shaped station core with lots of energy and the TORQUER feature.


Reassembler define 3 "starting" or premade ship:

- "Premature": Barebone ship with default core and thrusters.
- "Simplex" : Barebone ship with heavy core and thrusters.
- "Replicator" : The default station design with the station core.

To use the default core: Build a new ship or build a ship based on the "Premature" design.

To use the heavy core: Build a ship based on the "Simplex" design.

To use the station core: Build a station or ship using the "Replicator" design.


To obtain the new core in an existing game, you have two options:

1 - Go to the fleet screen and delete all your ships. Export them if you want to reload them after. Then, create a very basic station with just the default core and a factory. Using your 300+ P active ship design, spawn the bare-bone station. Since the R capacity of this new station is 100, it will start to spawn the two basic ships design namely, "Premature" which feature the default core and "Simplex" with the new core. Be patient, feed your station R and eventually it will spawn a "Simplex". Enter command mode, hover the freshly spawned ship and enter the fleet screen. Just drag the new design into an empty slot...

2 - If you don't mind using the console, this method is much quicker and easier. Stop your current vessel. Press the console key, check the key assignment section to find out which key to use. By default this is "\" (BackSlash). With the console window open and the mouse cursor hovering the window type "sopen 20_Simplex" without the quote then press enter. The new ship will spawn at the blue cursor position. Press ESC to close the console and return to normal gameplay. Follow the steps to move the design into your fleet from option 1.
