Sea of Stars: How to Beat the Catalyst Boss Guide

To defeat the Catalyst in Sea of Stars, follow these steps:
- Attack the Catalyst’s first two repeaters one at a time.
- Then, face its four guns: two repeaters and two repair units. The process should be the same but now prioritize the Repair Units.
- When finally facing the big, bad Catalyst, you’ve already got an idea of what its guns are like. Prioritize the Repair Units, then focus on the damage-dealing guns. When they are down, unleash all damage on the Catalyst before they respawn.
