keep trying t3erm3nt0r with the bike race. I found crashing into fencing worked ok for the limo one.

the false idols is so freakin easy. the only problem was finding a way to get the yellow patriot to my garage which i did once but it disappeared. My advice is to take out the limo then go to the park near the bottom entrance and the helicopter will slow down before heading towards the highway. the easiest is just to camp the radio station and blow them up when they are trying to park/land.

the hardest mission i think is the ambulance and firetruck missions.. i managed to get to lvl 11 but i ran over a patient backing up. And its hard to aim with the firetruck.
