Can IG take allies? Like an assassian or some sisters.. or marines?.. I'm a Nid player and i think i'm sick of being a 'bad guy' and i want to 'cross into the blue' so to speak. I've been thinking about the IG... Being a nid player i've rarely lost to an Ig army... well ones without the big flamer tanks anyway... so I was just wondering what allies the IG can take... if any.
