Starting off you just got out of the subway and need to take the steps
of the Reich, once you have control head to the left until you appear
outside the enemies stronghold. Rush in to the front and take cover and
make your way around it while running from the occasional grenade spam.
Once you have reached the corner go behind the building to the left that
dash down the front. You will see a window, there is a sniper in here
kill him, than as you turn the corner to the left kill the 3 or 4
Germans outside, hug the right wall and keep your eye on the broken hole
in the wall that lets you see in the building, there will be a German
right by the entry way and 2 more inside, kill them than head on out and
into the next building.

The building is covered with books and bookshelves all torn down, so
just rush in and around killing the Germans at the end hiding by the
desks. There is a lot of cover here, but you need to head up around the
right, once you eliminated them all, head outside in the trench and into
the tunnel for the second part of the mission.

Here you will need to eliminate 4 flak cannon crews, and this is really
difficult since you only get a checkpoint after taking out 2 but here is
my method after lots of trial and error the best way to do this is.

Immediately head right, use the wall by the tank for cover, than head
right to the steps along side the wall, you'll see a broken chunk out of
the wall which you can use to climb up. Once your on top prone and kill
the enemies to your right while slowly making your way up, you should
see the flak cannon dead ahead, throw a grenade and take out your gun
and pick off the enemies still surrounding it. Than move up, tricky
thing is sometimes an enemy is just hiding right behind the flak88 and
as you make your way to the cannon he jumps out and will shoot at you,
so take caution. The next troublesome part is you can't prone up to the
Flak88 you have to walk up allowing you to get shot from the other
10,000 Nazis here. So get up there, plant the charge and rush back down
and make a right to the tank.

Here you can pick up a Panzershreks, use this to peak out and take out
the Flak88 to the left of you, you will now have a checkpoint and have
to head forward to take out 2 other flak88. Your going to take out the
left Flak 88, so proceed up, just keep running for cover from the
grenades, but head to the left near the flak88 you should find some
barrels/boxes for some decent cover from fire. You just need to watch
your upper right where the enemies are coming in from the building, head
on up the steps and keep an eye out on the top of the building there
might be a sniper so kill him. Once your on top crawl near the fence
right by the flak88 and eliminate the crew, once it seems clear, rush
down and plant the explosives on it, than head right using cover
to regain your speed.

Now keep heading to the last one, Reznov should be taking cover right
here, so crawl and peek around the corner and take out the flak88 crew.
Once they have been eliminated slowly but not too slow get over there to
plant the explosives, now run back to your cover. Once they Flak88 have
been destroyed you will get another checkpoint and now have to proceed
up the German stronghold before the steps of the Reichstag.

This is pretty hard, but I found out a really easy way to do it on my
second time through. When you get your checkpoint, make sure you have
the Kar98k than head behind and on top of the building behind you. You
can pick off a good majority of the enemies here and there is a moment
when they stop spawning. So once you cleared enough to make it through
the buildings without a problem head forward to the right building. Head
inside and up the stairs, here you can find your self a panzershreks and
a PTRs sniper rifle, use this to pick off the people on the steps that
*you* can go up, not the ones on the left. If you kill enough people
here Reznov will tell your men to move forward and you will get a much
needed checkpoint.

Your basically going to do the same thing here, but before you do head
outside and to your right and look up you should see some sandbags and a
guy held up here. Kill him, than go back into the building and go all
the way to the back and snipe off people until your out of ammo, make
sure you don't keep killing the infinite respawns guys. Just pick off
the people in the building or held up by the building. Once you kill
some of them focus on the stairways defense and take them out. Now head
down stairs and up the stairway prone going to cover to cover. When
Reznov says, "Move Forward" go back downstairs and continue the same
thing. He will than ask you to come over, head back up the steps, a
pillar should fall down, go all the way down the stairs.

A Nazi with a flamethrower will torch Chernov and once he is dead go
with Reznov into the Reichstag, and this will end the level.

This is a horrendous level made from the depth of hell, it's really hard
to do even for the second or third time for me, it took about an hour to
finally figure out a strategy that now works constantly. Checkpoints are
weird after you destroy the Flak88 since my first time I got a
checkpoint when I went into the building, this time I had to destroy a
good amount of their forces to get a checkpoint. Either way, I'm done
with this level and so are you, now the final level approaches us.

-Edit-

Also, during the part where you need to take out the 2 flak88, I
previously thought they only gave you one Panzershrek, but there are 2.
The second one is right along the side of the stairs to the building
that leads to the right upper right Flak88, so you could technically
take out both further away flak88 with the panzershrek fire, the video
doesn't show the second one, but it's still useful just incase you miss
and have to do it the hard way.
