ARK Master Controller Boss (How to Summon, Fighting, Variants, Rewards…)

The Master Controller is a boss that you encounter in the Genesis: Part 1 DLC in Ark Survival Evolved, which appears to be a simulation-like being. 

As you enter his domain and progress towards it, the Master Controller begins with insults only but eventually becomes aggressive as you get nearer.

Its appearance appears to be similar to a holographic projection of a robotic head, which has a background that varies in color based on the difficulty.

How to Summon Master Controller?

To start the Master Controller Boss Fight (also known as the System Root) you will first need to have completed the following number of missions:

Master Controller Tributes

Fighting Master Controller

You will need to bring creatures with you to take on the enemies that the Master controller spawns into the area, these being Corrupted Avatars and Dinotars.

You will need to kill the spawns to obtain Data Keys which you will then need to turn in at the Codebreaker Terminal.

This will need to be repeated until the Master Controller becomes vulnerable and afterward you will need to rush towards it and attack.

Bringing Tek weapons is great for taking out other enemies but you must have tames that can handle them while you make a run for the Codebreaker Terminal.

Tips

• The Master Controller cannot be attacked until you reach the later phases, you will need to proceed with defeating the other enemies and collecting Data Keys.
• It is good to bring creatures that can withstand damage and deal a good amount to easily defeat the enemies for faster Data Key collection.
• You do not have to interact with Data Keys, they will simply be picked up if you approach them but you still need to collect and take them to the terminals.
