Saw this earlier where the Tony Hawk PC community has modded
the hell out of THUG2 even more. You can download below at the
link I added. They included more character customization options,
added levels, a toggle between PC/PS2 modes, and it runs in 1080p.
They have plans for a lot more stuff to be added. You do need a
copy of THUG2 for PC so I am sure you will need no assistance in
picking that up at various places if you don't have it already. The
mod itself is about 100mb or so.
