Cortana (level)/Walkthrough: Difference between revisions

:There really isn't any weapon that is weak in all situations. The only exception is a Plasma Pistol overcharge—while it takes out Brute armor very effectively, it does little to the Flood. If you get a Plasma Pistol, use normal shots. The [[M7057 Defoliant Projector|Flamethrower]] uses approximately the same amount of fuel for killing a [[Combat Form]] as for killing a [[Pure Form]]; therefore, save it to kill Pure Forms. Don't hoard weapons continuously, despite how much you may think you need them--if you hoard too many, you will overload the map. The most common result is that some weapons disappear or fall through the floor. But if you are trying to beat the level with Iron or else with minimal death, hoarding weapons is your best bet, although it is time-consuming.:*It is highly recommended that you find a replacement for your shotgun at the earliest opportunity. While the shotgun is an excellent in close anti-Flood weapon, there is limited ammo and are several weapons that can deal more in close damage more quickly without a need to reload. An [[Type-1 Energy Weapon/Sword|Energy Sword]] is far more effective, and a Brute Shot provides both the melee damage and a ranged attack.

:*Your MA5C is extraordinarily effective in short controlled bursts and accurate aim. It's ability to kill ranged forms is not as effective as a [[Type-25 Carbine|Spiker]] or [[Type-33 Guided Munitions Launcher|Needler]], but until you can find them, its high rate of fire and relative accuracy at close-to-medium range is superior to a [[Type-25 Directed Energy Rifle|Plasma Rifle]].

:Get the most out of your grenades, use them on clusters of flood, but keep at least two stickies (anything that is not a Frag). These are particularly effective against [[Carrier Forms]] because they kill not only the Carrier Forms themselves, but also the [[Infection Forms]] inside them. If you are having trouble killing something, say, a Pure Form in the large room near the halfway point, go ahead and throw a grenade.

:If you are a Halo 1/2 veteran, you probably made it this far, with difficulty, without using equipment. But on Cortana, equipment becomes a necessity. Deployable Covers are probably the best equipment; they do not self-destruct after a while, unlike any other equipment, and you can fire while protected if you are carrying a human weapon. ''Note: The Carbine cannot fire through Deployable Cover.'' If you cannot find Deployable Cover, use a Bubble Shield, as lesser forms enter your shield, you can kill them without worrying about exposing yourself to Ranged Forms. But when the timer goes out, you will be exposed. Cloaking is good for speedruns, it is also effective for crossing the larger open spaces without detection.

:It sounds ridiculously obvious, but more so than any other level it is true here. The Flood blend with the background and often times your radar will not detect the enemy because they are stationary. Always check behind you and be methodical when clearing areas.

:Each variety of Flood has a specific weakness. No one weapon will be effective against all (for example; The Energy Sword is excellent at killing flood, but its range makes it unsuitable against Ranged Forms). Understand that your best chance of survival is knowing what combination of weapons will provide you with quick short range attacks and excellent range, to maximize your overall damage.

:Due to the difficulty of this level using Iron is not recommended. If you do use it, be utterly methodical in clearing areas. Leave no enemy intact.

:There are no Regenerators and many Ranged and Infection Forms. Not recommended despite the vast amount of close melee situations you will be involved in.

:You will be surrounded very easily. However as your radar can often be deceptive on this level, if you do use it you're really not losing all that much of an advantage.

:Ammunition is scarce on this level, and why make it more difficult. Conversely there are a number of Weapon cases with fully charged items, so if you are an accurate shooter, and with all the meleeing you should be doing you can succeed with this skull on.

:This skull is probably the most annoying, but also the easiest to get around. Your plasma weapons will become very ineffective, but projectile weapons like the Spiker and Human weapons are twice as deadly. Being able to aim properly is key here as headshots with the Carbine aren't affected.

:Much like the "Tilt" skull, for experienced players it's going to be more annoying than anything else. Accurate fire and knowing your weapons will effectively negate the consequences of activating this Skull. For inexperienced players, and those with difficulty aiming, this skull can be a death sentence.
