I hate barnacles, so this is not the best position to be in, but they are actualy not that hard to beat at all, but still, creapy ones. On the other hand i love them, the way the makers created it, its great. That wobling and scrunsing movement and sound, i love it. As you have noticed another screenshot of hfl2 (half life 2). Its in the beginning of the canal section (note: a more recent pic, further up the canals, is posted earlier. and there will be, but becease i love the game, a extra pic.)
