You must try this patch!!!!!! A very, very good effort was put into this patch and I highly recommend it. These robots are the ED-209 Robots out of the Robo Cop movie. The patch replaces the troopers and they are deadly. There is a physics file that comes in the folder but the shapes are outstanding. The sounds file is a must. You can't get the full effect of these guys without it. Their armor makes them pretty stout, so watch out. The voices they come with are pretty cool!!!!! Great job!!!!
