Still trying to adapt to the new Tyranid rules and this one came up in a game the other day. I bought 6 of the buggers and as I read the rules Orbital Deployment means that I can deep strike them onto the board after sides have been selected and before units have been placed. So I can deep strike them all over my opponents side of the board? how much distance does he/she need to keep from my mines? 2" general and 12"-18" if infiltrating?
