Thanks both ricnunes and Lieste for the replies, this has been something i've been eye dating for a while,just like i did with rainbow six before finally wetting my feet . there was even a promotion not too long ago on gog that i missed because of my isp going down, either way i wouldnt have time to play it now but i really loved 688 as a teen and this seemed the closest that i've seen in years, i just love sub hunting.
