Take a Spectre, Ghost, or Wraith and use boost to get behind the Red base. Ramp over any
ridges and rocks. Go up on different rocks and ride along the walls sideways.
Additionally, on the right side of the Blue base, take a Ghost and boost at the wall.
There is a location that lets you drive straight up the wall. This trick has no strategic
advantage, because as soon as you hop out of the Ghost both you and the vehicle will fall
down.

In the first level, as soon as you get off the lift do not go on the train. Instead, look
to your right to find a trash can. Go over to it, crouch, and look in between the can and
the wall. There should be a Johnson Cigar burning away. Additionally, go to the armory. As
you are coming up the stairs, you will hear the man shooting his shotgun and talking. Kill
the Elites and go through the door. Jump over the turret and look to the right. Jump on
the lights sticking out of the wall, then jump over the rail. Get on one of the beams and
jump off it onto one of the rails. There will be a small room with no doors. Jump onto
that and bash the trash can. When you look on the floor, you will see Johnson's cigar.

To lock on with rockets, target a person, vehicle, etc., then hold R until it says that it
is locked. The red reticle will follow the item. Release R to fire. Additionally, while
using a rocket launcher, you can lock-on to the following items: turrets, vehicles, and
the Phantom's plasma cannons (Covenant Dropship's turrets). To lock-on to those objects,
aim your cross-hairs at the object. By doing this, your rocket launcher's cross-hairs
should have four red squares on the corners. Then, hold Fire so that the rocket launcher
will fully lock-on to the object. While this happens, the lock-on system of the rocket
launcher should make a few repetitive beeping sounds. After the beeping sounds have ended,
the cross-hairs should be completely red and ready to fire. Release Fire and your
spiraling heat-seeking rocket launcher missile will go to the target.

When in campaign mode playing as the Elite, press White to turn on the active the
camouflage. Use your active camouflage wisely -- it does not last long. Find the enemy and
an energy sword. Use the camo before the enemy notices as you are approaching them. It
will them be easy kill. Wait for the crosshairs to turn red, then lunge and slash.

When fighting the Scarab, the giant supertank, after it destroys the Scorpion it will
start moving towards you. Look to your right. There should be a thin ramp-like spot. Run
up this area before the Scarab reaches you and stand in the big flat area, watching it get
closer. When it reaches you and starts going over another wall, jump and you will follow
it. Normally the wall is too high, but when under the Scarab you can jump about twice as
high.

Get a Sentinel Beam and overheat it. Quickly throw a grenade and it will appear as though
the grenade appeared from the Sentinel.

There is normally a Ghost and Warthog on the lower level. To get one of them to the upper
levels, drive it into one of the air units that makes you fly up. It is strong enough to
bring up a Warthog or Ghost. You can now drive around the circle and run over anyone
standing there.

The plasma sword is one of the most deadly weapons in the game. However, there is a way to
make it deadlier. If you are walking up to someone, you will see the aiming reticule turn
red. If you press the trigger or B, you will deliver a deadly lunge that can kill almost
anything in one hit. To make this even deadlier, before you reach your enemy jump and keep
aiming at him. When the reticule turns red, you will still be in the air. As you are in
the air, press the trigger or B and you will lunge forward in mid-air. This is more deadly
because you are above himm and his head is the closest thing to you when you are in mid
air.

Go near a Wraith and press X. Then, press B a few times. Instead of throwing a grenade,
just hop in. If this does not work, throw a grenade in the Wraith.

Get a beam rifle (the Covenant sniper rifle) and fire it in the middle of their bodies
where it is pink. This is more effective then pumping shell after shell into them. Because
they have the new gun, getting close to them no longer works. There is another way to
defeat them, but it is more costly. First, take your plasma grenades and throw about two
or three of them on their pink skinny area. Then, get a shotgun (or the strongest gun you
have) and pump the pink spot full of rounds until it is dead. Since they usually appear in
pairs, this can waste a lot of ammunition and grenades.

You can kill Hunters without using any ammunition. If there is a Human turret nearby,
use it. You will do so much damage that they will drop quickly. You can also still get
close to them. Remember that you are a lot faster than they are, and pay attention to
where the other Hunter is located. Sometimes you can get them to hit each other. It is
also possible to melee attack them to death, but a lot of your Marine allies will probably
die.

When you encounter a Hunter on any level, use your melee attack and hit them in the
head. They will stand there for a moment, stunned. This is just enough time for you to get
behind them and kill them. Depending on how skilled you are, it may take a few times to
take them down.

When a Hunter charges, move out of his way. When he misses you, the pink spot on his
back will be wide open. Use the weapon of your choice to blast him.

The following is a list of rewards you get from killing people without dying once.
Note: After 25 it starts over again with "Killing Spree".



5: Killing Spree

10: Running Riot

15: In The Zone

20: Unreal

25: Unfreaking Believable

At some point in the game when you are playing as Master Chief, one of you allies will do
the Howard Dean scream while they are attacking.

When reloading a gun, press melee immediately after the ammo is reinserted into the gun,
press X. This enables you to shoot and/or zoom instantly. This works for any gun that uses
ammunition.
