i have played terminal velocity before, however i can not remember specific missions. i might need to play it again to get an idea of what i forgot.
i am gonna play system shock 2 after bf2, i expect to get to level hydroponics after maybe 1 or 2 days and the rest within the same time period afterwards. the game is good, the only problem i had with the game was, was the Rickenbacker, where a rather large section of hull was vented into space and you had to jump to another extendable walkway over that open hull breach without falling into it. i had to replay that mission a few times.
