Oh I expect the same One asteroid hit= One Kill. What was interesting about the "dead stop", is that I could never pull it off well on the PC. On the PSP, I can pull this off with out a problem. Mapping the L/R as the speed contorl was a great way to free up the rest of the controls. I still have a problem with the com system ( I find it akward pressing the trilange and select to scroll to the right reply. I would have liked to have had the D-pad mapped as the com system contorl just like the Star Wars space shooters on the PS2) but overall a great game. I am going to get kill more times then complet missions but I had the same problem with the PC game.
