At this point, Fritt Monkey has resorted to telling Butch what he already knows from listening to the audio logs. He threatens to blow up the whole planet with Butch on it and retire to a nice life growing roses on some godforsaken colony unless Butch can give him the chip in one hour. Now the race is on to reach the asteroid and put an end to Fritt's monkey business once and for all.

Also at this point, the game loses all semblance of difficulty as the developers give you unlimted ammo for the plasma gun. Look, at 0:34 you can even see the ammo counter shoot up from 1 to 999. It's like they knew they designed a horrible game and they were making it up to the players for all the shit they had to go through after the driving mission. I will admit the scale of this level actually kind of impressed me the first time I played. Kind of. But not a whole lot.
