QFT. Tyranids being around for a long time isn't new. Inquisition War - set in M36 - deals with Genestealers quite a bit. I'm also uh...Not reading Cain books for the time being anyway. Unless something has drastically changed about the character?
I'm told that Last Ditch is basically Caves of Ice 2.0. Has Mitchell delved into the NewCrons (the bad kind of Necrons)? Or are they still lol!Crons that just show up and kill everything and leave (the good kind of Necrons, the ones Mitchell wrote pre-new-Codex).
