TWO BETRAYALS

HALO>SINGLE PLAYER>LEVEL WALKTHROUGH>TWO BETRAYALS

Ideal arsenal: Shotgun and plasma rifle.
Best tip: Use the vehicles whenever possible.
Hardest part: Getting the last Banshee.
How to beat it: At the very end of this level, you'll find yourself stuck in an intense battle between Covenant and Flood. Stay to the far left side of the map, and make a daring run at the Covenant tank with your rocket launcher. If you survive, scamble to get the Banshee and gain air quickly.
Cool thing to try: Use the Banshee to wipe out every single enemy.

WALKTHROUGH

    Quickly get to the top of the tower and pick up a health pack and the sniper rifle... but don't use it yet. Get to the bottom of the dam as quickly as possible and get the rocket launcher that's on the right hand (facing the big building). Run back several levels higher and take out the tank from a distance. Return to the bottom and use the sniper rifle or the rocket launcher to take out the Gold Elite. He is your biggest threat as you try to get the Banshee.
    Use the Banshee to clear the bridge and then land on it, loading up on weapons and ammo. Keep your rocket launcher... you may need it. If you see aliens and the Flood fighting, let them fight, and defeat the weakened winners. Beware of Gold guys inside.
    Use a rocket or a charged up alien pistol to take out the Gold Swordsman. Let the enemy fight each other whenever possible.Pick off the winners.
    After you go through a long hallway, there will be a sharp turn. Lob a grenade around the corner and you'll take out a monster with a rocket launcher. The next bit is extremely difficult, but the basic idea is to make it to the bridge and wipe out everything behind you.
    Getting across the bridge is also extremely hard. The best idea is to cross s quickly as possible, using every bullet, grenade, etc.

SATISFYING THINGS TO DO IN HALO

Running over bad guys with the Warthog.
Taking out the enemy in one shot with the rocket launcher.
Pistol-whipping a sniper.
Sniping a sniper (they're easy to kill because they stand still).
Betraying a buddy with a pistol whip, or sniping at them. Also, you can run them over.

Once you've fought through the next building, you'll be back outside at a clearing. Jump on a Ghost and immediately focus on the aliens surrounding the tank. Side strafe away from the tank cannon and patiently pick off the ground forces. Once they're clear, fly down into the pit infront of the tank and get more rockets. Fly up high, hide behind a rock, and use the rockets to destroy the tank.
Fly down through the tunnel and then through the barrier (you'll fit). Flip the Warthog and take it up the narrow pathway. When you reach the top, jump out and use the turret. Drive until you reach the opening and the massive tower. Use the cannon to shoot down the Banshee, then the 2 Hunters on the right. Continue to the right, leaving your Warthog behind, and wipe out the tank with a rocket. Run up and get in the turret and take out the 2 Elites below.

    Jump into the Banshee and fly as high as possible. Destroy the other airborne Banshee, and then, from high above, pick off the targets below, starting with the turrets. Fly directly above your target, piont your nose down, and hold your left joystick back... this will allow you to hover out of reach of enemy weapons.
    Land on the platform. Enter and step into the beam to disrupt it. Don't be afriad to run. Otherwise, a shotgun is the best weapon for this part.
    Jump on a Banshee, fly into the tunnel, and wipe out all the resistance. Target the right side first, and you'll eliminate most of the rocket launchers. Watch out for more rocket troops around the corner. Open the door.
    Mak your way across the bridge, using grenades to wipe out small enemies and to make sure nothing gets behing you. Watch out for the rocket launcher.
    You'll see another battle going on. Stay out of it as long as possible. Go around the corner (the tunnel's blocked), and you'll see another battle in action. Let them fight, and take out the winners. Take out the rocket launchers on the left side by running at them and fighting at close quarters.

Now you've got one ground battle left... and it's a toughie. Stay to the far left side until you can get into the base. Regroups, reload, and then make a run at the closest alien with your rocket launcher. Immediately jump on the Banshee and gain altitude. From here, you can head to the waypoint or exact some revenge. Once you go to thee waypoint, you'll be attacked by drones. Stay up high, as they don't shoot up.
