Okay, the most unfair, was Call of Duty 4 veteran. the level where you are stopping the warheads from hitting the USA, i got into the facility, and it announced i had 9 min
"Okay, im fine with that"
I get HELLA close to the end.... and die
i get sent ALL the way back. too little save points in CoD4 Veteran, and i played through only good enough for Regular by the games standards
EDIT - And for the post above me, Vet, Mcmillan, what i did -
Put him down, and as you are facing where the enemies come from, run to the right, and lay behind the bumper car arena. Once the time is up, get mcmillan without dying, and you are good, you take no damage with him on your shoulder
Beat the game, proved them the hell wrong lol =P
