That wasn't the Wilhelm, but yeah, it's an overused sound effect. The best name anyone could find for it was on the TV Tropes "Stock Scream" page, and they named it ""aaielalialiaaah!" It's been in a ton of video games.

What was even better was how it was re-used three times in rapid succession.

"We're five by five.". Yeah whatever.

Aliens was such a great film, but if I hear one more idiot use that "five by five" phrase like they're actually a badass...

We'll just have to nuke 'em from orbit. Only way to be sure.

Except there's nothing to understand. It's all stock plot elements and loads of cliche. Whoever's animating it has some talent, though.

I like to think they lied to get him to attack the telekinetic dude.

"Hey, we got this guy with terminal cancer who wants to be killed by machine gun fire."

"There's also no way we could have gotten a robot or animal to test this on either."

"Sir? We've found the man you're looking for. He's a bloodthirsty gun-nut who really, really hates those guys who go to gaming cons with a bunch of d4's glued to their scalp."

"Excellent. Feed him a case of energy drinks and send him to the lab."

This is what happens when those secret organizations "you can't quit" have to fire someone.

Not all Evil human resources people (redundant?) just shoot incompetent minions, the passive-aggressive ones just arrange work 'accidents'.

also the robots have a better union.

Nobody wants to shoot a hot naked woman.

I'VE GOT SOMETHIN I'D LIKE TO SHOOT INTO HER

She'd read Watchmen a few too many times.
