Discovering the entire galaxy is quite a challenge due to the size of the galaxy and the amount of fuel used.
I believe that even the greatest achievement is to complete all the tasks that can be found in the galaxy.
I explain:
We have 125 constellations to discover and a minimum of 20,000 missions. (I do not include missions that are available to people with CHL and key rush mission (I consider them additional missions)).
If we complete all missions in Constellations …
we will get a shard to construct a reward.
The notification of the achievement will come to notifications.
A total of 125 Shards can be obtained.
If we get the right amount of them, we will get the achievement:
Apprentice of an Authentic Hero
Reward for completing all quests in 40 constellations.
Veteran of an Authentic Hero
Reward for completing all quests in 80 constellations.
Successor to the Authentic Hero
All quests completed!
