When dealing with an infestation of acid-blooded insectoid aliens, you're bound to run into certain situations that require extra care and consideration on the part of you and your Aliens: Colonial Marines buddies. Let's take a look at some of these.
First off, there's the alien popping out of the floor and dragging your buddy down below situation. Your first instinct is going to be trying to grab his hand, pulling him back up to safety. This is a bad idea.
At best, you'll end up holding a severed body part. At worst, you're going down with him, leaving your remaining squadmate unprotected. Sometimes you just have to let go.

Ew, facehuggers! Time to open fire!
While it may seem like killing these sickening little throat-f**king bastards is the best course of action, take a moment to survey your surroundings. They are locked in a lab, behind heavy glass. They'll die out on their own soon enough. Opening fire will just increase the chance that one of them will force a romantic rendezvous with your esophogus, and you're in too dangerous a line of work to become a father.
This is alien-fighting 101 stuff here. If you see a xenomorph on the other side of a closed door, keep the door closed. C'mon kids, these are the easy ones.
Oh screw it. Go ahead and tap on the jar, you idiot.
If you can see this, you are too close. For some reason alien eggs rapidly hatch upon contact with a human's field of vision. You're pretty much doomed. Game over, man.
