One of the more novel aspects of the Bioshock games was the Speargun pinning the Splicers to whatever was behind them, in conbination with the 3D Ragdoll Physics for the struck bodies (often dragging/flying them a ways til the Spear pinned them in place). Actually the Spears appear to strike with rediculous force able of making the body fly a dozen feet sideways, or carry it up to be tacked to a ceiling. Real Spears are sharp, with a low effective transmission of friction - in other works it would really tear through bodies if it had that kind of force. --- --- --- --- --- --- --- --- --- . . .
