Proceed on mission and move forward. Eventually as you enter a structure you will hear Jun call out that he has detected movement. This is your cue to pull out your pistol. As you move along you'll come to a window overlooking a small grassy courtyard. On the roof of the building to the left, across from you, is a [[Skirmisher]]. He'll stand still for a few seconds, so use the opportunity to take him out with an easy pistol headshot. Now you know, [[The Covenant]] are on [[Reach]]. A few more Skirmishers will charge across the courtyard into the basement of your building. If you're quick, you can take out some of them with your pistol before they get inside. Stay where you are for now. Some Grunts will also start moving across the courtyard towards your building. Thin their ranks with pistol headshots. Take note of the large red fuel tank in the courtyard. These explode very powerfully if shot enough and are found throughout the game, so make use of them. If the cap is blasted off the top of these tanks they become powerful time bombs that will detonate after around five seconds. Head down into the basement to deal with the Skirmishers that made it inside. They are extremely fast, just as agile, and good shots with their weapons. Get some cover and use your pistol and grenades to deal with them. Head outside. Two Grunts will wander across your field of fire on your left as you move down the slope. You should have no trouble taking them out. A [[Dextro Xur-pattern Spirit|Spirit]] will drop reinforcements across the river, a mixture of Grunts and Skirmishers. Use your pistol for headshots and toss some grenades to clear them out. You and your team will make short work of this group. Take a moment here and reload. Pull out your Assault Rifle before you continue. You will want a Plasma Pistol instead of the Assault Rifle on Legendary, so swap out for one. Run across the river and take out the Grunts that are visible. Now things get tough; it's your first encounter with [[Sangheili|Elites]], and unfortunately for you they are high rank and not pushovers. Expect four Ultra Elites, accompanied by a General. They are much faster than you are and their shields are over triple (quadruple on Legendary) the strength of your own. Stay back and let your squad weaken the shields on the Elites. Use the overcharge shot on the plasma pistol to help out. Once the shields drop, use your pistol to headshot them. Once you've mopped up this area, reload and get ready for part two.

Break's over. Hop out of the Falcon. Clear out the remaining enemies here, head up the stairs on the side of the building and load up on ammo, if you head further down, you'll see an entrance to the building and an armor lockup. Grab it and hop down. This next part is pointless and a waste of time, but you have to do it anyway. Run in to where [[Catherine-B320|Kat]] is working, peek out and kill anything that gets in close, but nothing will, because it's not scripted to. You just have to prevent yourself from being killed here. Don't expose yourself, and pick off whatever comes into your line of sight. If you do choose to engage stick to the building on the right of the door, it will provide you with significant cover from the [[Dextro Xur-pattern Spirit|Spirit's]] cannon fire. There will be 2-3 waves of Covenant, Grunts, Jackals, Skirmishers, and a few Elites. Right after you get the notification that Kat has completed her hack two Banshees will fly by and bomb the door. Watch out for them! They're often not noticed because the ground action is so hectic. Wait until they attack before you run inside if you engaged outside, those Fuel Rods hurt and will one hit kill you on Heroic or higher. Once the door closes, head inside. You'll trigger another cutscene.

Presto chango, you're back in the fight. Swap your pistol for a DMR on the wall and watch out. Many Grunts and Jackals will advance, while a [[Sangheili Zealot|Zealot]] with a [[Elo'Nakada-pattern concussion rifle|Concussion Rifle]] sits back and launches an endless barrage at you. Note that on the right side of the room there are three fuel tanks. Blow the lids off of them with the DMR for explosive results that should take care of the cannon fodder. Concentrate on the Zealot. Only break off the attack to reload or recharge your shields if required. Kill him quickly or he'll run away and the next part of the level gets that much harder. Keep picking away at him with the DMR. It should take around a magazine to drop him if you don't miss. Once he's down, advance and use grenades in the hallway to clear the remaining Grunts and Jackals. Reload, and head into the next area. It is populated with Grunts and another Zealot with an [[Type-1 Energy Weapon/Sword|Energy Sword]], and he's a lot craftier than his friend was. Once the Grunts are cleared he will charge quickly but steady fire from you and the DMR and Assault Rifle (don't stop to reload, just switch weapons) should slow him down enough for you to either drop his shield and peg him with a grenade, or headshot him. Since he will usually make a beeline straight for you once you've got his attention, sticking him with a grenade is very effective and should deplete most of his shield. Melee is very dangerous because of the Sword. If you need it, the drop off area below you contains an [[M45 Tactical Shotgun]] and a Drop Shield (which you can use to help defend yourself and regenerate health). Once you've killed him, go and activate the panel on the wall to trigger the cutscene and move on to the next mission.

*Watch out for the [[Dextro Xur-pattern Spirit|Spirits]]. They will kill you faster than any ground Covenant forces.
