Hint: Double turbo:
Quickly press X(2) and your car, boat, or motorcycle will get turbo. Slow down and use normal fuel for the turbo to recharge.

Hint: Classic Spy Hunter: Avoid enemies:
When the weapons van first lets you out, keep going straight and use the turbo until you get to the second part.

Hint: Level 1: View motorcycle transformation:
In the first level where the car turns into the boat; when approaching the weapons van go through the cones in motorcycle mode to go past it. When getting towards the end of the level, go through the cones once again to return through the level. When you get to the ramp where you can watch the transformation, approach it to see the motorcycle transform into the jet-ski.

Hint: Level 1: Skip jet FMV sequence:
On the level 1 where your car turns into a jet car in slow motion, when you approach it, go slow to the right side. If done correctly, you will have saved some time and can complete the level faster.

Hint: Level 12: Less transmitters to destroy:
When you first start level 12, "Locked Systems", you will find a couple of the transmitters that you need to destroy through out the mission as a secondary objective. Take the second bridge on the right side and the game will automatically reduce the number of remaining transmitters to destroy. The bridge also the has the helicopter. The stealth gate will as well reduce the number of transmitters remaining in the mission.

Glitch: Slow FMV sequence:
Acquire the Hover Spy, put it on, then go to level 1. Get to the part where it transforms into a boat. Once there, it will slow down.
