Query: Mortal flaws in the gameplay.

Nice graphics and action packed! Too bad they messed it up with a stupid combo system... In order to unlock all characters, you have to complete 'Konquest' mode - this means you will have to do combo's etc. But some of the 3-style combo attacks are nearly impossible to pull off. I've been playing beat'em ups from day one and I found myself struggling with Raiden's combo for half an hour!! Honestly, I felt like performing a fatality on the disc.The gameplay is also very tedious. If -for once- you opponent DOESN'T block your attacks, you would be stupid not to use your best combo. So you find yourself performing the same tricks over and over again. The game also gets ridiculously hard after a number of consecutive wins, even on medium mode.
