Yep, old stomping grounds. This area is now flooded, but you can walk on water, or ice I suppose. Move up and into the building for your own cover. Now your team will go out to die, so there’s little you can do. But from here you can pick off the turret gunners, an enemy with a cannon to the right, and pick off ghost driver so you can ride in it. Use the ghost to clear the enemies at the other end.
Then move up to the scorpion ahead. Jump in and let your buddy get on the turret. You control the cannon, so test it on the enemy platform. More tangos around the corner, and just know that well-placed shots are better than inaccurate fast ones, for the most part.
Head up the slope and you’ll see AA guns online. Move up and hit the enemies, then the ghosts, and some banshees that are hard to anticipate. Then just start pounding the turrets as they will explode from your cannon fire.
Once down, you get some air support so help them clear out the skies before moving on. Head down the path for some ghosts and a platform. The slope heading to your target is covered with vehicles and turrets. The turrets are top priority, especially the one up on the cliffside, it’s very deadly. Get the other turret at the back and then climb up the hill to the gate.
Get out and run in. Elites meet you while the smaller minions are handling nearby friendlies. The path to the lower level will open with more elites and turrets down below, but you need to go left to wash up the enemies or your team won’t proceed, so get any covenant up here before going down low. Pop the turret gunners, then take one with you.
Head up the path and use the turret to plow into the next room, which has many levels and lots of jackels crawling around. Just move slow, maybe use that hologram power (sends a ghost of you as a decoy) and you can get to the top.
Grab a DMR and move to the other end for the dark path. Toggle vision and move through the familiar grounds to emerge at the foyer. Just a few elites roaming, with most cloaked to eyes sharp. Your hologram is a nice tool here to draw them out, and especially clever on the zealot that appears on the ramp in the right corner. Take him out, move into the room, maybe an enemy in here, and open the door for a scene.
Move up and get ready to turn on four turrets in the area. The lab is to the left, and all you really need to do is survive the duration, which is about a good 4 minutes if not longer. The turrets recharge when they take too much damage, and you can see all their health bars on your screen. So it’s advantageous to help them mow down incoming, at least early on.
About when the ghosts show up is when you should fall back to the door and stay there. You got grenade launchers on the sides, a spartan laser (aim, hold, fire), and even a rocket launcher here to help you defend. The latter waves are mostly elites, with the final wave having enemies with those big cannons. Just stay mobile, more around, and use your hologram. Don’t worry about the ghosts or wraith, they are really just traps. When the phantom shows up is the best time to use your spartan laser and rocket launcher, to attempt to blast it away. Soon after the doc will be done and you can open the door to enter.
