OMG this map is fantastic! It's huge (Forge World huge) wide open and flat (perfect for Forge) and you can build near and on the water again which is great. But the best thing about it are the trees! There are 50 forge-able trees along with many new rock types (one of which is a giant wall)- this map is perfect!
I've got no doubt about that i'm just dissapointed i can't give it a shot, i've missed so much in the Halo universe, there was obviously a good reason as to why it got through certification so quick, i'm glad even now they're still bringing new content for it.
