you haven't DL it yet?
this is my first ride in the hog when i got the demo -
having not read the read me file, i couldn't figure out why my guns weren't firing - i read the keyboard commands doc. i'd armed my hog, and even pressed C for cannon (couldn't figure out why i had to do that bit, put it down to it being a beta) and nothing happend when i pulled the trigger.. had i read the read me file, i would have found out that i had to first press 7 to put me in A-G mode... DOH! ;)
pls note the un realistic loss of fuel from the wing - a) as there isn't even a fuel cell in that part of the wing and B) the wings are the first cells of fuel to b used as they aren't protected by the self-sealing cells like in the body of the aircraft, this is so they are dry when the pilot enters combat.. but hey, its beta buld 5 :)
