This bit of news didn't quite fit as an extra paragraph in the previous post. It's also of interest that fAt1 reported contacting PC Gamer to ask why they hadn't yet supplied a feature on Halo. The person responding told him to look for issue number 83.
After calling an assistant editor at Imagine Media, I verified that there is actually a separate UK version of PC Gamer which is probably the magazine fAt1 is referring to. The US version uses a different numbering system. (The April 2K magazine is Volume 7, Number 4) Hopefully you Halo fans in the UK will let us know as soon as you see something.
