You'll find yourself in the Great Hall immediately. You'll have to set up defenses to hold this high ground from a couple of waves of enemies. From the front door, there is an infinite stack of COG ammo to your left, along with COG weapons (Lancer and Gnasher). You'll find grenades near the middle and two turrets that you can move overlooking the lower section. The Glowing Omen is next to the turrets on the statue.

| "Kilo Squad alleged that Onyx Guard unites had improperly set up defenses and that Nemacysts infiltrated the Museum." Nemacysts will join the ground attack. |
| Throughout the entire battle, Nemacysts will pour in through the broken windows at the top of the Great Hall. Try to put a tall column between you and them to allow you to fight while being protected from them. I'd highly recommend that column at the top of the right set of stairs. If you stand behind it and a little to the right, most if not all of the Nemacysts will fly into it without damaging you and while allowing you to attack the enemies climbing the stairs. |
Grab the two turrets and set them up. The Ranged turret is pretty good on the raised section looking over the left set of stairs (near the ammo) while the Gnasher Turret is pretty good just at the bend halfway up the right stairs. Put it just around the bend as you are coming up so that it will only fire at enemies as they round the corner. This will keep it from wasting ammo firing at distant enemies.
Grab a Lancer and Gnasher, stock up on ammo and grenades and then get ready. The first wave will consist of assorted Grubs and Boomers of all varieties. From the part overlooking the fountain, you should be able to reach the E-Hole just behind and to the right. Toss a grenade in. Take cover near the column at the top of the right stairs so that the Nemacysts fly into the column instead of you.
Always go for the Boomers first because the turret should be able to handle almost any Grub that comes up the stairs in a shot or two but the larger Boomers will be able to do some serious damage to the turret (and you) before going down. Remember to reload the turrets if they run out of ammo. Unless a Boomer comes up these stairs, you should be able to hold out against anything from this position. If that does happen (sometimes you'll get several Boomers at once) then back up to the railing just behind you. From the glass case, you'll likely be able to shoot just over the railing at the taller Boomers without them being able to hit you back since their weapons are halfway down their bodies.
The second wave will be much like the first but there will be a much heavier emphasis on Boomers. Make sure to stock up on ammo between waves. Once you've finished the second wave, check the fountain in the middle of the area before proceeding. On the far side of the fountain but in the water you should find the [COG Tag]. Head for the door.
