This sanctuary now rings with the sound of combat - the end of the ancient duality of the Covenant is truly at hand.
Gemini consists of a closed-quarter outside area and an open inside area. Teleporters can warp players up to two small balconies on the top of the inner area. Another teleporter warps players to the outside and back. There is a wide array of weapons from close ranged Brute Shots and the Energy Sword, to Carbines and a Beam Rifle. An Overshield can be found in front of the Prophet statue.
One of Gemini's unique features are doors that open and close when a player gets close.
