16807 Obscure Hieroglyphic:

I thought I heard somewhere that there would be a very basic one. Nothing like forge or the editors for previous games, though.

 Well if it’s not even like Forge I don’t think it could be called a Map Editor. I have been watching most of the Halo Wars previews and news very closely and I have yet to hear anything about a map editor.

If a PC version ever arrives the SDK may ship with it. It would be very interesting if there was something like Forge for Halo Wars though. But I just can't wait to get my hands on the game, editor or no.
