You'll start out under fire from the helicopter gunship but it'll get shot
down. Follow the team through the gap in the fence. Throw smoke grenades to
cover your approach to the vehicle and use nightvision to cut through the
smoke. Hopefully you don't get run over >_<. Plant a C4 packet on the rear of
the vehicle and detonate it from behind cover. Exit to the east, and turn
south at the road. Take cover in the building marked with '2'. Exit towards the
east, hugging the buildings on the right. You'll advance towards a gatehouse,
where one of your soldiers will blow the gate with a charge. Before heading
through the gate, go behind the south building across from the gatehouse.
Collect the ammo and pick up the laptop for a piece of intel (27/30). Head
through the gate and continue east into the first building across from the gate,
and wait for a BMP to stop near you. As always, its easiest to approach from the
rear. Blow it, and advance towards the farther one. On your way to the second
armored vehicle, head southeast towards the hangar-like structures. Go into
the middle one of the three that you see on your minimap and pick up the laptop
from the ground next to some barrels (28/30). Take up a position by the exhaust
vents and rappel down as soon as you are able.

An alternate way of doing this level is to go around the chain-link fence
towards the north. Plant a C4 on the indicated area and kill the enemy troops
among the cargo containers. When the first BMP appears you can retreat back out
the hole you blew to the truck and use the RPGs stacked up by it to take it out
without having to get up close and personal. Instead of following the road to
the south, keep heading east to the blocked gate, and up the rusted stairs. This
rooftop overlooks the silo area where two additional BMPs attack. You can use
the Javelin launcher on this roof to make quick work of the two vehicles before
jumping over the railing and rejoining your team for the level exit through the
air vents.

2.3.3 'No Fighting In The War Room'

Crouch and follow Griggs through the ventilation shaft. You'll drop down into
the shower area. Exit through the door Price is peeking around and turn right
into the hallway with the yellow strobelight. From this point on, on Hardened
difficulty anyway, you have 11 minutes to make it to the control center and
abort the missiles. Turn left and kill the men running down the hallway around
the corner to the right. Continue down the path, which is quicker than the
right because it bypasses the kitchen. Turn left into a dark meeting room to
pick up the laptop facing away from you on the table. Keep advancing until you
reach a room divided into two halves by crates in the middle. Kill the enemies
annd then proceed behind the crates, and down the stairs. Turn left and proceed
down the extremely long hallway. The most expedient way is to go along the
parallel side corridors to the left or the right. Before you charge bravely and
suicidally down either path, throw a flashbang in to blind any potential
ambushers. Rejoin the long hallway and then turn left at the corner. You'll see
yet another long hallway. Again, there are two parallel corridors, so pick one
and clear down it. At the end of the main hallway, go through the door and Price
will secure it behind you. Gaz and Bravo Team will open the launch bay doors
from the security room, but it opens ridiculously slow. Throw a flashbang in,
and hug the right wall around to a brick room with two flashing red strobes.
Plant a C4 packet where its indicated, and blow the charge. If you still have
a flashbang or two now is the time to use it. Go through the hole you blasted,
turning left and running for cover alongside the workstations. Help your team
clear the area and check the briefing room near where the other team breached
the control center for the final piece of intelligence (30/30). Go down the
central aisle separating the workstations and enter the abort codes using the
keyboard on the left side as you're facing the main viewscreen. You have to
hold down the action key while your character enters the codes. Just tapping it
won't do. Follow Price and Griggs back out of the hole and go down the hallway
eliminating the enemy soldiers. Board the elevator and ride it up. Exit into
the vehicle depot and with the rest of the squad, clear it of all hostiles.

2.3.4 'Game Over'

This mission starts as a standard rail-shooter mission that's been a staple
of CoD games. Crouch for cover if you need. Make the RPG trooper on the truck
behind you a priority. After a while, you'll pass through a couple of tunnels
and cause a crash between a fuel truck and the one chasing you. Pick up the
RPG launcher next to you and try to take out the helicopter. It'll fly off but
then reappear, taking out the bridge in front of you. When you regain control
of your person, jump northeast as soon as you can to get off the falling
section of bridge. Take cover behind a nearby wrecked car and shoot at the
pursuers. A Hind helicopter will fly for a final pass and wipe out most of
your team. Zakhaev and his men show up to execute the survivors. One of your
friendly soldiers will slide a pistol to you. Use it to kill Zarkhaev and his
two cronies to end the mission and the game.

2.4 Epilogue

2.4.1 'Mile High Club'

Note: You have to sit through the credits to open up this level. As far as I
know this mission isn't related to the plot in any way. Kill the terrorists as
you proceed towards the front of the plane. You have 1 1/2 minutes to find the
hostage. Note that you can shoot through seats to hit the terrorists behind,
but the same is also true for yourself. Go up the stairs at the front and turn
around, killing the opposition. Aim down the sights of your pistol and kill the
terrorist before evacuating the plane by jumping out.

4. Cheat Codes

I can't for the life of me understand why someone would need cheat codes on this
game but for those who can't resist, here they are for your reading pleasure.
GameFAQs user 'cekken' posted it on the boards for public use so I am just
making it easier for people to access.

Note that to make use of the codes, you have to enable the console in the
'Game Options' menu.

Here it is in its entirety, his post regarding the codes:

Hit the tilde key (~) to drop the dev-console.

Type seta thereisacow 1337 and then press ENTER.

Type spdevmap and then press ENTER. (This step is what was making cheats not
work for some, unless you type spedevmap and then hit exit when it says it
could not find map, cheats will not work.. found this out after tweaking
around last night).

Once you hit spdevmap and exit back to main menu, resume your saved game or
start a new one and cheats should be working fine!

Type the following codes in from the console (~) to activate them:

Code - Result:
give all - Access All Weapons
god - God Mode
noclip - No Clipping Mode
notarget - Enemies Ignore You
give ammo - Full Ammo
jump_height # - Adjust Gravity (Default = 39)
timescale # - Adjust Time (Default = 1.00)
cg_LaserForceOn 1 - Add Laser Sight to All Weapons
