Kingdom Hearts 2 Final Mix / Cavern of Remembrance / 3rd Nobody wave
Lots of Nobodies to fight, no place to hide. And occasional Sorcereres that combo you to death. Everything needs to go just as planned or you die. And I mean, everything. You let up for a second and you are retrying.
Well, at LV1 at least. It wasn't much different when I frst got through it at LV49 on Critical Mode. Still tough as nuts.
Then there's some Eliminator races in MotorStorm Pacific Rift. The last one I have to clear has sooo rubberband cpus.
And how could I forget Arkham in Devil May Cry 3? After you get Vergil as your partner, you lose some of your vital moves with Dante. At least you can still mash <-+triangle with Nevan to get rid of the minions. But with Vergil, ohohohoho.
You know what, what if I just say "Kingdom Hearts Birth by Sleep at LV1"?
That game is just plain ridiculous, all the technical issues the game has tends to ruin the performance, a living lock-on, crappy block and frame rate drops to name a few.
But at least I learned to play properly. It was a high price to pay, believe me.
