My Y axis is inverted! How to fix that

At the part after you have alerted the whole village, you have to run back.

While you are running, plant the animal traps down. Try to put them near places of cover, as that gives you a high chance of a enemy stepping on them.

The traps are not able to hurt you. Just don't get distracted when placing them.

If you have the Engineer perk it will be highlighted in red with red shading making it very obvious. Failing that, its usually fairly obvious if no-one on the opposite team is trying to get the care package.

Also the lottery of what is in the care package is reset. Meaning that it may change from a UAV to a Sentry Gun.
