When they made the second film there was a campaign by the censors to cut out virtually all the gore like we see in the first film, that seemed to carry on through the AvP films and Predators too. Who could forget Jesse Ventura getting a hole blown through his chest or Bill Duke getting shot at point blank range with the Preds plasmacaster or Carl Weather's arm getting shot off and still carries on fighting. Similar scenes were shot for P2 but cut out, surely the censors couldn't object after films like Saw 1,2,3,4 etc...
