It seems that in one of the zombie maps for Black Ops you're barricaded in the Pentagon as...JFK, Fidel Castro, Robert McNamara and Tricky Dick Nixon. 
Wasn't planning on getting this on release but...goddamn, that sounds like fun.

EDIT: Now with video. BE WARNED, THE FIRST THREE MINUTES ARE THE ENDING OF THE GAME. DO NOT WATCH THEM. Fast forward to 3:00 for zombie fighting.

They should have put Lincoln in it.

Too soon.

Kinda awesome.
 
Edit: That IS awesome. Im picking Castro every time.

Holy shit.  That's awesome.

omg This is wonderful.

They can do this? Either way, fucking awesome. Especially loving that last pic.

" Too soon. "

That is freaking awesome! I'm really considering buying this, everything I hear sounds good, and it seems like they will fix the problems from MW2.

That's pretty awesome. I'm getting more and more excited for Black Ops the closer it gets to release day.

I am seriously considering getting black ops now

Video is up all over Youtube now.
 
Here's one

The Pentagon Zombies opening cinematic is quite possibly the greatest thing I've ever seen.

How the fuck is the amazing thing that happens AFTER the ending of this game not a spoiler?   Is there any reason you couldn't have been a little more vague in the thread title?
 
Fuck, I'm done with this forum until after Black Ops.  Thanks a lot.

Finally, my dream of playing as Nixon has been realized. I can't wait to bowl some zombies away! 
(it's a joke about Nixon being an avid bowler)

that is awesome Nixon all the way

They'd made for a great cast in Left 4 Dead 3: History in Turmoil!

You are an ass hole for the title of this thread OP.

This is so awesome. Now I will definitely buy this game and have no regrets for doing so

Man that's too awesome. One more week!!

I did not know this was a spoiler. But thanks for telling me that it is, guys. :/

ok that is fucking cool
I'm so glad they put  McNamara in it, i bought mw2 and wasn't planing on buying black ops but the multilayer stuff looks really good

God damn Nixon for life.

Treyarch's motto: no gimmick left behind.

When do they reveal big head mode?

 It's all a conspiracy

I pretty much just spoiled the ending for myself from that video. GODDAMNIT. 
 
Same fucking deal with MW2's ending. 
 
 
 
This looks pretty awesome though.

Can we not talk about the fucking ending.  Thanks.

I was able to see the video, but now this comes up: 
 
  This video is no longer available due to a copyright claim by Activision Games Inc.

I watched through the entire video but I didn't feel spoiled since I didnt have any idea what was going on.

Ich bin ein shotgun, bitches!

Can't wait to play as Tricky Dick.

The movement in the video seemed really weird but Nixon should be fun to listen to. Makes me wonder why not make it McNamara, JFK, Castro and Che Guevara just seems like a weird matching or why not replace Castro with LBJ.

I would consider this spoilers but whatevs. Looks awesome.

Dude, whaaaaaat? That is some ill shit right there.

Dude... awesome.

Alright. Done. Sold. Richard Nixon murdering zombies.

Woo JFK all day baby.

Even IF MoH had Shakespeare and the Raptor....it still would have been outdid by this.
 Holy crap that's amazing.
