The UNSC from the Halo line converts well into the 40K rules as long as you just use humans. Marines are the Imperial Guard (or whatever they are called now) Spartans are the Space Marines and ODST can either be elite Imperial Guard or Space Marine Scouts. The vehicles would take a little more work to convert but I'm sure it could be done.ZeusEQ wrote: I'm really into miniature gaming, so I'm sure I would use an existing ruleset, or come up with a ruleset of my own, for WH40K battles/skirmishes at the MB scale! I'm already working on some rules to introduce in my gaming group to use with the CoD line figures :D.
The Call of Duty figures do work well for table top war gaming as well although you may want to do a Google search for a rule set closer to modern warfare stats (unless you want your commandos using LasCannons ... lol).
A friend of mine is working on a rule set that we've tried with Call of Duty figs and block built terrain (some pictures on my Flickr page but you have to scroll down a ways). We've got another test coming up this weekend, I'll post some pictures in the Fan Gallery afterwards.
