The Hidden City of Balkai was a multiplayer level in Ratchet & Clank: Full Frontal Assault. It resembled the other Ebaro maps, but was rainy instead of snowy. It was a more complex map than the others.
The Hidden City of Balkai was the only map that had Grungarian Missile Minions and Bombers surrounding a base or an area.
Grungarian Soldiers were placed at node one, but taken down after an update.
