Do clothing, jetpacks and vehicle upgrades help you in Jetpack Joyride

All of the Jetpacks handle exactly the same way. However, some of the jetpacks have a flame or other output that can harm scientists on the ground, and some of them are perfectly harmless, which is something to keep in mind for some of the 'don't harm any scientists' missions.

Sometimes you get unlucky with the obstacles, and once the game gets going really fast, a lot of it comes down to luck.

You can purchase the High Mobility gadgets (the Super Sneakers & Gravity Belt) if you what to change the game play physics.

Try using the gravity belt and the turbo booster.

With the gravity belt equipped its safest to fly about 3/4ths up the screen. The gravity belt helps with your reaction time: you'll be able to drop below high zappers pretty quickly. Then get back up to the 3/4ths level as soon as you are able. At that height you can jetpack above any mid-level zappers.

The turbo booster is useful because you're invulernable every time you hit a boost. Alternately you could try using the de-zapinator, but I didn't find it too helpful since it is unreliable.

It really just comes down to having split-second reaction times.
