Fleetbreakers Nexus & Discovery Tree Guide

What changed in Nexus V2

Developer notes describe the Nexus as the ship/relic/etc. inventory. The older layout was confusing enough that players could equip a squadron accidentally; the V2 layout was rebuilt to make fleet management clearer.

The Nexus workflow between missions

The gameplay tutorial shows the full between-mission loop that runs through this screen: accept or decline the reward choice, replace ships you lost in the ships panel before starting the next mission, assign powers to your mothership, and review the squadron you just added. New squadrons granted mid-run appear here first, so checking the Nexus before warping is how you avoid launching a fight with a half-replaced fleet.

• Rewards can be declined. Tutorial runs show uncommon offers being weighed against current fleet needs rather than auto-accepted.
• Mothership power slots are assigned here; the tutorial notes that tooltip clarity was limited in its build, so verify what a power does before committing.
• Replacement ships cost resources, so the ships panel doubles as a budget check before the next node.

Mid-mission squadron deployment

Tutorial footage shows additional squadrons being deployed during a mission: press and hold on an empty squadron slot, then choose which squadron to bring into the battle. The same footage reports that there is no drag-box selection, so squadrons are commanded individually. Practice this once in a safe mission so the deployment reflex exists before a fight that actually needs it.

Discovery Tree is easier to navigate

The August update added the ability to zoom all the way out on the Discovery Tree. That matters because persistent unlock planning is only useful if you can compare branches instead of buying the next visible node by default.

Prioritize unlocks that change run decisions

The May 2026 notes also confirm ship-selling at the Vendor is gated by a Discovery and can be upgraded by later Discoveries.

• Economy access such as Extractor-related unlocks when resource pressure is your repeated failure point.
• Vendor / ship-sale options when inventory quality and resource conversion matter more than raw capacity.
• Defensive infrastructure or Repair Mothership access when attrition ends otherwise strong runs.
• Faction-specific colony tech when it directly strengthens the build engine you are using.
