Building The First Rapidium Ark
Before you can build the first Rapidium Ark, you will receive a call from Terrance Maxwell. This happens in Act 1 of the game.

During this call, he explains is the boss of Jan and Lucas and assigns you the Rapidium Ark task. This task comes with the blueprint needed to create the module in the Alters.
Players need to gather 30 Metals, 120 Rapidium, and 100 Organics to build the Rapidium Ark in the Alters.

Once you have the materials, head to the Command Center in your base. On the left side, you will find the craft option, which you can interact with to build the Rapidium Ark.
Lastly, after building and placing the module, go to the communication room and contact Maxwell again to finish the task.
