I realized that I haven't made any contracts in The Final Test. I'm very happy with this attempt. It's hard to make an interesting puzzle in that map, so I added a restriction:
You must complete this contract without ever entering the airport fence.
It's a really fun and interesting puzzle. Gotta shoot lots of cars. I managed it in 1:16. (It might actually be optimal to stay outside the fence when playing normally.)
