Taming the majestic Astrocetus, commonly known as the Space Whale, is one of the most thrilling experiences in ARK: Survival Ascended. This massive cosmic creature from the Genesis: Part 1 map offers incredible mobility, powerful area attacks, and the ability to travel through space. However, the taming process is complex and requires good preparation.
The Astrocetus can only be found floating in the space zones high above the Genesis 1 map. Unlike traditional tames, you cannot simply knock it out with narcotics. Instead, you must force it down from space using specific tools and then protect it during the vulnerable taming phase.
