Hardest level ever?

So what do you think is the most fustrating/hardest level ever? Icouple games gave me trouble

OddWorld Strangers Wrath- the second to last level where you have to get across the factory problem is there is a time limit abd its barely enough time just to get across let alone trying to take out all of the enemys in your way, it literly made me cry in frustration and I finaly beat it by pure luck.

ForzaMotorsport-Laguna Seca course- thid idnt a level its just a track the I was never able to master, every time it came up on a champinship series it always gave my trouble. because there is alot of sharp turn that will send you into the dirt if you miss them.

Call of Duty 2 on veteran- every level is extremely hard but if I had to pick on it has to be were you have to defend city hall from the constant flow of germans, you have to snipe the the MG43, kill the germans that get inside the building, and take out the half tracks with the panzerfast, ALL AT THE SAME TIME!!

MotorlKombat Deception- the final boss- that stupid dragon boss who is impossible hard to beat, he can take alot of damage and every attack takes almost half my life. there is also this training mission in konquest (yes its spelled with a "k") were you had to hit the guy before he hit you or something like that I can't really remember.

Thats all I can think of at the moment, any level,boss, racing track make you break your controlers?

Genocide City from the Sonic the Hedgehog 2 beta is harder to complete than any of those.

I'm not saying that these are the hardest levels ever, I just wanted to share levels and bosses that I had trouble with and so others who had trouble or faced a difficult boss could share it with the rest of us. so has anybody faced a hard or fustrating level or boss?

I agree with that COD2 level, the fact that your team-mates seem completely incapable of covering the stairs themselves make it near impossible.
