Best map i've done this, its fair big but its got lots of feature's and lots of place's to go. There is also a pretty good sniping spot if you can find it.
I've not played on it myself yet because every time i try to host a game, regardless of the map i always get a message saying "Game could not be created"
Here are the details
Map Name: Deep Unknown
If anybody does D/L or play on it, let us know what you think.
