At the moment, every boss in revengence!
I played the game on hard at a friends and got to Jetstream Sam killing all the bosses, including body double of mistral and monsoon in one go ... even did Sundowner fight the cheese way without knowing. Now I own the game, I will be buggered if I can parry!
Don't get me wrong, I know how to parry ... push the analogue stick in the direction the red glint comes from and hit light attack, which I do but half the time the attack still lands.
I'm thinking it's my controller, it's not a case of "maybe I did get it wrong, maybe I didn't but I'm so good that it is the controllers fault" it is very much me being absolutely certain I am putting in the right command but it failing me. Like when Sam does his 4 hit combo, I am pushing the stick right at him and hitting light attack ... I will block the first, third and forth or first and fourth or any combo for that matter, might block them all or none.
Biggest bull shit was yesterday, he had a tiny chunk of life, I had a tiny chunk of life, this was my 20th attempt, he back flips over a rock, I do the command to parry ... Raiden attacks the rock! I panic, hit the parry again, ANOTHER SLASH AT THE ROCK! Sam obliterates the rock and me along with it! I go to bed ....
