Sentai Headquarters Reviews
Brickipedia
“Sentai Fortress, located at the end of Tenchii Bridge, was the primary base of the humans of Sentai mountain, lead by Sensei Keiken, in their battle against the robot army, lead by Meca One. The set features the robot army attacking the fortress and its defense by the... More members of Exo-Force.”

“Nice design overall. This is basically a sci-fi castle. It uses the same modular design as many recent castles. The robots are a bit bare, but they aren't the main part of the set. This is one of my favorite sets! I think it's the best exo-force set ever. I might get a... More second set just for the pieces.”
