Cortana (level)/Walkthrough: Difference between revisions

:Unless you have beaten the level on lower difficulties, keep your MA5C, no matter what.  You'll need its compass.  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.  Human weapons provide an advantage if you are using a [[Deployable Cover]] in that you can remain where you are--safe--and fire on the enemy.  [[Type-25 Carbine|Spikers]] are particularly effective against [[Flood Ranged Form|Ranged 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.
