«Cepheus» - is not the answer to Europe's threat. This is a question that the ocean doesn't have an answer to. Our weapons shatter rocks and flesh. Our electric shock burns out the very darkness. Our shuttle will take the troops anywhere, and our drone will highlight every crack.

But true victory is not only over the enemy, but also over the madness of the depths. Therefore, there is a garden here that provides fresh food. The bar where the brotherhood is born. Cabins where you dream not of the reactor noise, but of silence.

The depths are no longer a hostile environment. From now on, they are our domain.
