Eh - can anyone get past the part in this video 9.23
It says you need use the 'grab' button, which is shift on the PC, but I can't seem to do it on the XBOX. Do the controls need a tweak or am I just not getting it?
Also - is anyone having problems with the save states? I had it saved right at the point above and I just tried reloading it to try again after typing this and it loaded a previous, much earlier save-state instead.

Hold Right Trigger to hold onto ledges.
Save states seem ok so far, I think you have to make sure your on the correct Game State Slot.
