3. 🎮 Compiler Boss Fight Guide: Mechanics and Recommended Weapons
· Approaching the green orb initiates the Compiler boss fight.
· The core of the boss fight is matching three icons on monitors around the room. Success generates a green shield in the center of the room.
· Standing inside this green shield allows you to destroy the Compiler's shield, followed by a damage phase of approximately 10-15 seconds.
· Throughout the fight, the Compiler randomly fires laser beams and releases tracking orbs. Be careful, as being hit twice by these orbs can result in death.
· Interacting with monitors renders you immobile for 3-4 seconds, making you vulnerable to tracking orbs during this time.
· Shotguns are inefficient in this boss fight. Instead, Vault weapons are most important.
· Vault weapons can store a lot of ammo, which greatly helps in damaging the Compiler and handling various mechanics.
