How to unlock the Immortality of a Kind achievement in Surviving Mars - Definitive Guide
Your colonists will age as the game progresses, but if you really want to rush this, turn off the oxygen, water, and electricity to your domes.
Is there any way to reliably obtain this? Map Co-Ordinates which definitely have it on them? Any other way to make sure it is one of the breakthroughs in a particular playthrough?
Someone on the subreddit recommended this location: 16n32e . They also recommended doing the Marsgate mystery and saving before the conclusion, as you can reload to get another random Breakthrough reward.
The second part is very simple; request a rocket full of passengers and give them only a dome with no water or oxygen. They will soon bite the dust and have a 50% chance of being revived and unlocking the achievement.
Project Phoenix is a breakthrough technology. You can discover a maximum of 19 out of 55 Breakthrough techs per playthrough, and the order you receive them is randomized but if you always pick the same location to start the game, it will always give you the same 19 techs but in random order, so this is somewhat luck based, therefore it is better if you start a new game without any Mystery selected as Mysteries usually will take up 2 of the 19 breakthrough technologies. If you did not get these breakthrough techs on a playthrough, then you must pick a different location to start the game the next time.
Analysing Anomalies throughout the map with RC Explorers will grant a chance for up to approximately 15 breakthrough technologies to be discovered depending on how many Anomalies there are on the map, whereas the wonder The Omega Telescope will reveal the rest of the breakthrough technologies that have not been discovered, up to the maximum of 19 per playthrough as mentioned above.
Once you have research Project Phoenix, there is a 50% that a Colonist that dies can be reconstructed as a youth with the same traits, so pass the time and wait for it.
