Once your guys are lined up and you start a new turn, move everyone forward to line up in cover and trigger the Big Bad Ethereal. Get him up high just inside the doorway (archangel armour necessary for this, with advanced flight you have more than enough fuel for any level/situation). This gives you change to get all your guys in the room and spread out however you wish. The Final big boss ethereal WILL NOT TRIGGER if you are not past the steps leading down into the middle of the room (I put guys on either side of the steps without triggering). the other 5 can be whatever floats your boat (I'm a fan of 2xSupport with Sentinal, 2xAssault, 1xHeavy) Just thought I would share my tips for how I clear the final room in the Temple Ship quickly, easily and in 1 move.ġ)Sniper - Squadsight - Double Tap - Archangel Armour - Advanced Flight
