Between the rulebook, Stronghold Assault and the FAQ for the previous codex I have become a bit confused. Can Tyranids now manual fire building weapons? I was thinking that a gribbly version of the Wall of Martyrs Imperial Bunker with a gribblified Quad-gun would be helpful against flyers, but I don't want to do it if the Quad-gun will only be auto-firing (Rulebook, pg. 96) at the nearest enemy unit. If anyone knows the answer to this, a reference to a page with the rule would be nice. If the answer is just "it doesn't say that you can't" then I may have to wait for an FAQ before I put in the work to make something and risk having it taken away like the Parasite of Mortrex that I custom-built. Thanks!
