Verified class boundary
Custom endgame kit
Abilities, status, and source links are separated from editorial recommendations.01 // Confirmed record
Abilities confirmed for Specialist
The confirmed boundary is customization: abilities can be mixed into a custom Marine. The precise unlock path remains unresolved on this site until a first-party record gives the steps.
Evidence: Official game site

02 // Squad use
Where this class fits in a fireteam
Editorial starting plan: begin by solving one squad need at a time—survival, lane control, or focused damage—rather than treating every available option as a mandatory hybrid.
Best understood as the flex record: use it to cover a gap in the other three players' base-class choices.
These are editorial play suggestions, not developer-confirmed best builds. Patch changes, difficulty, weapons, and squad composition can change the right answer.
03 // Video reference
