Trivia Note: In the Aliens series of movies this weapon always seems to be a hazard. i.e. shooting an alien with this weapon would cause a character to get splattered with acidic blood. This event happens a lot in AVP: Requiem. However, in reality, a direct shotgun blast would NOT splatter any blood "towards the shooter" or "to the sides". The force alone would direct all brain and blood splatter AWAY from the shooter. All one has to do is look a real life crime scene photos of shotgun blasts to the head. All particles or viscera are blown away from the barrel, none are to the front and very little if any is to the sides.
Additional Trivia Note: As the previous trivia note says, little 'splashback' if any would be expected. That said, the Aliens are well known to be extremely tough beasties, so who's to say parts of the body were not damaged very much by the shotgun blasts? This could have resulted in the 'splashback' as softer tissue and blood rebounds off harder bone / chitinous tissue...
Remember reading in a book or online when I was in school that the aliens had extremely high "blood pressure" resulting in them pretty much exploding when shot and in effect turning them into a walking anti personnel mine.
- Even if they are under pressure, the blast would blow the blood AWAY. I shot a pressurized Paint balloon with a shotgun for a demo once. Sure it flew everywhere EXCEPT where I was because the blast of the shotgun forced the particulate matter in the other direction. I am very wary of any theory that has the alien blood at such high pressure that it can overcome the kinetic energy of a shotgun blast.
