valhalla is one of my favourite maps of all ego-shooters of all time !

Yeah, I was stoked when I first read this on Gaf, Valhalla is a great map. Come to think of it, I really like most of Halo 3's maps.

Man, I have been waiting for a proper flood mode ever since Halo: CE. Glad to see they are taking steps in the right direction!

Still, my ideal flood mode would contain marines and flood spores :P Hopefully they will develop this idea further...unless they already have but haven't showed us anything yet.

Have you said this before?
