Cortana is the penultimate level of ''[[Halo 3]]'', and arguably one of the most difficult of the franchise. Your mission as stated is to find [[Cortana]] on the [[High Charity (Structure)|High Charity]], free her from the [[Gravemind]] and eliminate the [[Flood]]. | ||
Your most valuable pieces of [[Equipment|equipment]] in this level are [[Deployable Cover]]s and [[Bubble Shields]]. [[Cloaking]] is also handy but extremely rare. It is recommended that you always have a Deployable Cover with you. [[Grenade]]s are also your friends here; [[Plasma Grenades]] are very effective against [[Flood Ranged Form]]s and [[Flood Carrier Form]]s, and [[M9 High-Explosive Dual-Purpose Grenade|Fragmentation Grenades]] will thin out large groups of Flood and bring down shields on any shielded [[Combat Form|Flood Combat Forms]]. Beware, though: if you have bad aim, you will be penalized in this level. [[Flood Growth Pods]] line High Charity's walls and if you are inaccurate you will unleash torrents of [[Flood Infection Form]]s that will make you waste valuable ammunition and probably kill you. | Your most valuable pieces of [[Equipment|equipment]] in this level are [[Deployable Cover]]s and [[Bubble Shields]].

Using [[Halo 3 Skulls|Skulls]] on this level is not a good idea for inexperienced players, but using the Catch skull provides you with a distinct advantage, as the Flood do not use grenades, but upon death, they will almost always provide them. | Using [[Halo 3 Skulls|Skulls]] on this level is not a good idea for inexperienced players, but using the Catch skull provides you with a distinct advantage, as the Flood do not use grenades, but upon death, they will almost always provide them. | ||

At the mission start, use your Assault Rifle to clean out the Infection Forms. Make sure they do not re-animate any of the nearby corpses. Collect some grenades before moving on. Plasma-based weaponry is more effective against shielded Flood, should you encounter any, but for now stick to your current weapons. | ||

Eliminate them quickly so that the infection Forms don't re-animate any bodies. Head up the sloped path to reach the chamber's upper level. Find some grenades and replace your Shotgun with an [[Type-1 Energy Weapon/Sword|Energy Sword]]. | ||

Stay sharp because combat forms with human weapons will appear. Take them down with quick bursts from your Assault Rifle, then close in on them and finish them off with the Energy Sword. Back away slowly and look out for the Carrier Forms that will appear. Use a grenade that sticks (Plasma, [[Spike Grenade|Spike]] or [[Type-3 Antipersonnel/Antimatériel Incendiary Grenade|Incendiary]]) to kill them. When killed with a grenade, Carrier Forms won't unleash Infection Forms. | ||

For the next area you' | For the next area you'll want to be quick. Follow the path up and around. You should see a couple of Deployable Covers here. Grab one and make your way to the large opening in the wall, leading outside the High Charity. There are many Combat Forms here as well as [[Flood Stalker Form|Stalker Forms]] that like to become Ranged Forms. Load up on ammunition here at the [[Pelican]] and get ready to move. You can grab the [[M7057/Defoliant Projector|Flamethrower]] here. It can be a great help on lower difficulties, but on Legendary difficulty it is best to leave it: you will probably end up getting killed by burning Flood forms. From here you have a choice, you can set up your Deployable Cover and shoot out the Combat and Ranged forms, or you can run past them. You're going to need as much ammunition as possible, so while you could clean out this area (and if you're playing the [[Campaign Scoring|Meta-Game]] for points you should) you're much better off just running back inside, going to the left, and making your way to the porta and to the next area. The Flood will not follow you once the porta closes. | ||
The room | The room behind the porta contains a small slope and several Infection Forms. The chamber is filled with dead [[Sangheili|Elites]] and [[Jiralhanae|Brutes]], as well as some grenades. You can throw a grenade to set off a chain reaction and weaken or kill any Flood that re-animates. Finish the Flood off with the Energy Sword. In the next tunnel, grab either a [[Type-2 Energy Weapon/Hammer|Gravity Hammer]] (good for clearing away Flood if you get surrounded) or a new Energy Sword (usually the best choice), and then drop through the hole to continue. | ||
