I'm not really sure how old this is but it seems to be stimulating some interest pretty quickly. Really quickly actually.

Yeah read up on it. I would do this, but you need to PC version of COD4 to do it. I can't wait to see what this turns out to be. If you look at the screenshots of some of the examples in their forum, none of them really look the same and it looks like the software has a lot of variety and freedom. This looks to be potentially cool.

'See the castle one? Dude, that'd be wicked for sniping.
or like a "headquarters" or "sabotage" thing to play in.

If I made one It'd probably be one huge tall building that was like maybe 4 stories but the top 2 were smaller than the bottom. Then there would be a relatively small outside where one time would spawn and the other team would spawn at the bottom of the tower. I think it would play out pretty interestingly.

Wait half a year and see how many sick custom made maps theres gonna be.

They should make a mod for cod4...srlsy. Just like G-Mod.

The map editors of CoD are damn smart. They made so many good spots that there isn't a place for an attacker to just camp all the time.
