A walkthrough for Call of Duty : Black Ops – Rebirth
by Kenneth Stubbs (OmegaMustard)

Rebirth
————-
You will start out in a cargo crate.  You will be prompted to open the
door.  When you do, sneak up behind the guy cutting up stuff on the table
and melee him. You will take his hatchet and stick it in his throat and
then drag him into the shadows. 

Intel – Left of the guy that you just killed, in the corner.

Now run and stay right on Reznov’s tail. Follow him under the boards on
the left.  Now wait for the helicopter to pass over.  Now follow Reznov to
the end of the crate that just got placed.  Wait for the three guys to walk
by and now follow Reznov to the house but don’t hide, run up to the guy
standing between the two houses and melee him.  You will pick up his gun,
now follow Reznov around the houses and into cover.  As soon as it passes
over, follow him up the stairwell.  Climb the ladder and you will be
promtped to melee.  Do so and finish climbing the ladder.  You will be on
a higher balcony, now climb the next ladder.  When you reach the roof,
you’ll see an explosion and the base is now on full alert.  Go right and
fall down onto the lower roof and make your way across.  Jump on the pipe
and climb on the next roof. Enter the doorway and fall down onto the
catwalk.  Now jump and climb down the pipe that Reznov climbs down.  You
will pick up the roof door to the elevator.  Shoot the two soldiers talking
to scientists and fall in. You will be attacked by some guards in the
hallway right outside the elevator.  Run out and take cover behind a wall. 
Take out the enemies in this hallway and make your way down.  A guy will
try and sneak through the room on the left once you pass.  Turn around and
wait for him.  Now take your time and kill the enemies in each part of the
labs.  Don’t forget to kill seven monkeys in ten seconds for the
achievement/trophy.  Once all the labs are clear.  Pick up one of the
AK7u’s with the grenade launcher attached. It will be useful for the next
room.  Enter the big command center and fire grenades at the guys on the
second floor.  Now clear the room.

Intel – After clearing the big control room, it will be in the middle on
        top of some monkey cages inside the missile looking pod.

Now go through the back door into the hallway with Reznov.  Go to the door
at the end of the hallway and push it open.  You will watch a cutscene with
Dr. Steiner and then it will black out to you in the interrogation room.

You now take control of Hudson and you are in a tank 20 minutes earlier
to the cutscene you just watched with Steiner.  You will make your way
down the road.  There will be soldiers evacuating the station.  Shoot the
two guys on the roof with rocket launchers so they don’t blow you up. Then
shoot rockets and the two cars with soldiers hiding behind them.  You will
then move up and turn left.  Fire rockets and the blockade of soldiers
at the end of the road.  You are gonna turn right here. Be ready to fire
two rocket in the left and right corners.  Then fire two at the trucks
driving by right in front of you.  Now fire more rockets and the back
in the middle where the helicopter drops some more soldiers at. As soon
as you pass the building on the right, look right really fast and start
bombing the hell out of the enemies dug in here.  This part is very
frustrating on Veteran difficulty.  As soon as you take out the guys on
the right, you will turn left, quick aim a rocket at the stairwell on
the upper left for the two guys that spawn up there.  Now shoot rockets
and the car on the left and right and then at the jeep and pulls up on
the left.  Now just bomb down the land right in front of the fences because
this is where the enemies spawn from and start running at you.  You will
cross the bridge and a helicopter will come and bomb your tank.  They will
also cover the area in poison gas.  So now you are armed with a rifle with
a thermal scope.  Make your way through the gas picking off enemies as
you see them.  Your squad will move up as you clear them out so you will
know when the coast is clear.  Go through the house.  Kill the enemies you
can see through the windows and move up.  You will get close to the second
marker and the building in front of you will blow up.

Intel – After that house blows up, enter the house on your right and it
is sitting on some shelves.

Go through the house that just blew up and go upstairs.  Kill the enemies
waiting for you in the backyard and the guy sitting in the window on the
left of the house.  Once they are taken out, enter the next building and
head downstairs. You will now have to take out two helicopters.  Pick up
the Stella homing launcher and shoot the helicopters.  Once they have been
taken care of, head towards the alley.  Keep going straight and the gas
will clear.  Pick up one of the AK7u with the grenade launcher and fall
down the little cliff.  If you didn’t die by having your suit cracked, you
will get an achievement/trophy when you fall down the little cliff. Make
your way down the hill.  Pick off the soldiers on the roof of the building
that is shooting the rocket launcher.  Make your way near the buildings
and some enemies will run out at you.  Take them out and move up.  I think
they enemies ifinitely respawn here if you don’t move up so clear out the
way a bit and sneak up.  I found it easiest to sneak up the left side. Make
sure you take out the guy in the left buildings window.  Once you get close
to the building on the left, you will get a checkpoint.  Now move up a bit
and two guys will spawn on the roof and a guy will spawn in the main
buildings window.  Take them out and clear the enemies spawning out the
main building a bit and go up to the windows of the main building.  Kill
the guys running down the stairs and the ones shooting from the back office.
Now enter the building.  Go to the hallway on the left.  Take out the
enemies here and move up to the stairwell.  Kill the enemies that run up
to attack you.  When you get to the bottom of the stairwell, keep going
office to lab to office.  There will an enemy here and there that you must
kill but just make your way to the room where Mason and Steiner were.  Once
you get there, you will watch a cutscene and then you will make your way out
and end the level.
