Quoted from stevevt:Shootout on Dirty Harry. Seems easy, but there's not enough time. I had a DH for 6 months and I never finished it. I'm sure it's been done before, but they definitely made it too hard.
Shootout is completely impossible. I've run through it tons of times and never come close. I hear people saying they get it regularly but that's got to be a weaker setting. Standard is 20 seconds...insane.
