Information you need to know about dealing with Hunter Aliens....
Don't follow up a distress signal if the caller does not answer.
The likelihood is he's probably out to lunch...
And if you do, don't dream of resting your rifle against a tree.
Even if it's only for a few seconds- always keep it at hand.
Never be the funny or cool guy who makes all the wise cracks because...
he's usually the second to be iced. The reason being is if he were the last to disappear then the movie would be classified as a comedy not a horror action.
Likewise, if you have any valuable skills or abilities.....
gets you no where.... Have you not learnt yet
If you notice a shadow that moves and you're standing still...
then that's not your shadow.
And finally, should you inevitably bump into a hunter alien,
have a catch phrase handy that you remembered from an opened Christmas cracker. In the jungle you can scream, as it is not space and everyone can hear you. However, you will probably be mistaken for a howler monkey...
Hope that was useful.
