This is the flood and they are scary on many levels!
Make this into a movie its gonna be so scary like Alien vs Predator!
1.Infection forms and carrier
They are irritating in many ways!
The carrier will explode and infection forms will come out and they may go into corpses and turn them into combat forms!U can kill them while transforming into flood forms with a melee.Carriers should be killed by throwing 2 grenades and firebomb grenade(flamethrower can)
Infections should be killed with automatic weapons(assault rifle etc.)
WARNING:i might be wrong!

2.Combat forms
On higher difficulty they can be dangerous in groups.
Their weak spot is the infection form in the chest(the place where the red thing sticks out)Elite variants may have shields and can be quite difficult to kill.
I suggest using plasma rifles and brute shots(battle rifle and carbine can but shoot the infections in their chests.
3.Pure Forms
Scary types of flood
3 types.......
The Stalker form
They are quite lousy and perform range attacks.Pure forms are generally weak against the energy sword
The Range Form
Fires spikes at u.If it does not know where u are it will change into a stalker and look for u.Very weak against brute shot.
The tank form
The strongest pure form performs melee attacks.Its weak spot is its 'face'

Well thats all Merry Christmas!
