Barrel Flying

Barrel Flying is a useful tactic possible only in singleplayer. To do it, stand on a barrel, then place the cursor on the barrel, and then to activate Kinetic Module (press and hold the C button). Slowly lift the barrel to any spot you want. This will make the barrel fly with you on the top of it. It is recommended to take care to avoid sharp or sudden movements, as you could fly off the barrel. Try to also stay away from enemy fire.

Trivia
This technique is usually used to get on top of high walls or to fly high over enemies to the end of the level.

Barrel Flying can be used to skip the Rope section of Level 7 with ease.
