the PC version of Universal Century Online Demo:
http://www.universalcentury.net/02_play_meth_bench.html
download the 98.7 MB file and then run it...

i can run the demo with my nForce 2 IGP as it just needs a 32MB Direct 3D Compatible Card, wonder if V4/V5 can run it with better framerate/ better image quality..
enjoy!
