Sea of Stars: How to Beat the Catalyst Boss Guide

To defeat the Catalyst in Sea of Stars, follow these steps:

1. Attack the Catalyst’s first two repeaters one at a time.
2. Then, face its four guns: two repeaters and two repair units. The process should be the same but now prioritize the Repair Units.
3. 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.
