When your playing Campaign, you'll encounter a new group of enemies called
the Flood. Here's some things you should know.
Weapons to use:
Out of the variety of weapons offered, I'd say your best off using the shotgun
against all types. One hit, one kill. Simple as that.
Best on: All types
The Pistol is decent, but It's better for long range, due to it's rate of fire.
Best on: Carrier Forms
The Assault rifle is so-so, but it's not so good against combat forms. Even if
you do bring em down, sometimes they'll still be alive and they'll get back up.
Best on: Carriers, infections
The sniper rifle has basically no effect whatsoever on the combat forms. Shoot
them and it'll do nothing. Go ahead. Ignore me and try.
Best on: None.
The Rocket launcher is going to kill anything in the game, so duh it will work.
Just don't use too close...
Best on: All
The needler isn't much, but get a good amount of needlers on the combats and
you'll probably get them.
Best on: Infections, Carriers
The plasma pistol is just as useless as the sniper rifle. It won't do crap to
them, except for maybe the carriers and it will kill the infections.
Best on: Infections
The plasma rifle is slightly more useful than the sniper rifle and the plasma
pistol, but still doesn't do anything to the combat forms, except making you
waste time trying to kill one enemy.
Best on: Infections
About grenades, ONLY use the plasmas when they're FAR away from you. If you get
one on a combat form, RUN FOR YOUR LIFE. They are almost twice as fast as you.
Plasma grenades work best if you put em' on the ground and back up as they
charge at you. Both types of grenades work fine though.
Meleeing will NOT effect the carrier and combat forms at all. This is a good way
to deal with infection forms.
What the flood forms look like.
Infection forms are those little squid-like creatures that scurry along the
walls and floor and eat enemies alive and turn them into vessels. You can let a
couple pop on your shields. Just don't let too many or they'll eat you alive,
The combat forms are the bigger forms and they are the main uses for combat.
They are the only ones that can use weapons. Their usually either elites or
marines (anyone look familiar?). The Covenant Forms look like they have an
elephant trunk on their chest and head and are more deadly and they have
slightly long tentacles. The Human Forms are the ones that have their heads
tilted back and you can see their bones sort of. They are less powerful than the
Covenant Forms. They are very deadly with weapons, so watch out. Both types ran
run a lot faster than you and can really jump high. Also, if your fighting them,
do NOT get in a corner and KEEP MOVING.
Carrier forms are the ones that look like they're inflated bags. That bag thing
they have contains some infections. They are powerful and kill anything near
them by exploding, releasing the infections. They are slow however, so they're
easy to escape. They were either grunts or they were combat forms that had too
much damage to fight. They're easy to kill. Just a shot or two with the pistol,
assault rifle, or just use the shotgun.
