Recently picked this up cheap, enjoying it pretty well bar one thing: I totally don't understand how to chain grapple with grappler class dudes. I realise its probably just a timing thing on inputting the next grab but I can never do it, the game is no help and I couldn't find any other info on it elsewhere.

Anyone who can shed some light on this?

you just need to play with the timing, practice makes perfect.

Damn, was afraid someone would say that :p Cheers tho
