I got 50AP. You have to first beat it down until Zell says 'Let's get the hell outta here!' Then the machine will start to repair itself. Someone will say (I think Zell) 'Is it repairing itself?' And you just keep attacking him again and again until he is fully repaired. After that he will just fall down again and Zell, again, will say 'Let's get the hell outta here!' Then you escape. Then you get 50AP.
