You know whats weird? And sort of shows hows everythings linked.
This thread appeared yesterday (for me) and yet, last night on 5th Gear, after viewing this thread, they were talking about it, and how they made it... spooky...
It showed outtakes and how the cogs kept missing each other, and the wheel when going up the slope when pushed slid to the side and kept falling off.
That half life 2 things great. It just shows how complex the Havok engine actually is.
