Hi. Steelth. My memory is a tad hazy but isn't there a pit in the middle of the area? I seem to remember you have to make you way down into the pit and the end of chapter sequence is triggered. If that isn't it, post again and I'll load up the game and jog my memory.
You're dead right about the controls. Once you realise how powerful (and how much fun
) kicking and melee is, the game transforms. Have fun.
Cheers
