Unlike Halo 2 or World of Warcraft Classic , Star Wars Force Arena was a mobile live-service title. It didn't have LAN support. It didn't have a private server toolkit. When Netmarble flipped the switch, they didn't just turn off matchmaking; they turned off a piece of Star Wars history.
If you find a claim of a working 2026 server, treat it like a Sith holocron: Dangerous, probably fake, and likely to explode your phone.
If you are a : No. Do not bother.
Until Disney decides to remaster and re-release the game as a premium offline title (don't hold your breath), the "private server" you seek exists only in your holoprojector’s memory.
