How to Beat Subject 47

Run and Shoot

Subject 47 will move quickly across the battlefield, it is recommended to run and avoid its attacks. Players may shoot at Subject 47 when it finishes casting its attack.

Attack After It Lands

After Subject 47 lands an attack, there will be a brief period where the boss is idle for a few seconds. You can use this window of opportunity to attack and strike the boss!

Target Weakness Exposed

Subject 47 Attack Patterns

Line Explosion Atrack


The boss will charge towards the player and leave a flaming path where it ran across.
How to Dodge Be sure to sidestep right before the boss charges at you! Avoid staying in the path of the flames until the explosion is released.

Savage Roar Attack


Subject 47 will unleash dark orbs during this attack. They will surround the boss and move outwards.
How to Dodge It is recommended to distance your character away from the center since the orbs will be difficult to avoid up close.

Raging Roar Attack


This attack has a wide AoE compared to the other moves! A dome will increase in size and pillars will have flashing indicators on where they will strike.
How to Dodge Find the gaps between the flashing indicators of the pillars and use that space to avoid taking damage. Make some distance away from the dome too!
