“Star Trek: The Experience” is ending its 11-year run at the Las Vegas Hilton on Sept. 1.

Since 1998, millions of guests have boldly gone into the 24th century to battle Klingons, Borg and other hostile aliens, according to the operations manager.

The original complex featured the Klingon Encounter, an interactive adventure and ride. In 2004, Borg Invasion 4-D was introduced, and the Secrets Unveiled Backstage Tour began in 2005.

Operations manager and director of marketing Chad Boutte said the following in a news release:

“Hailing frequencies open. We’d like to thank all the fans and friends of Star Trek, whose constant and amazing support we’ve enjoyed throughout our tenure at the Las Vegas Hilton. As we boldly go into the futures that await, know that we take your love of ‘Star Trek: The Experience’ with us. We share the memories of time spent in the most unique place in the Galaxy, and we carry those memories into our futures with us. Live long and prosper. Hailing frequencies closed.”

There was no word on what, if any, attraction will be replacing “Star Trek: The Experience.”
