Only the large textures are done on that side of the map. Most of the small textures and foliage have yet to be added. The other side isn't even started yet. Here's a picture of the whole map:
There will be the usual FFA and DM modes, but it will feature a "king of the hill" objective mode. Your team must hold a flag on top of the ridge for 3 minutes to win. Once you capture the flag, there must be a player from your team on the ridge to score points. The allied team will start on the left (unfinished side) and the Japanese start on the right. It is for the HITP mod, so it has all Japanese skins, weapons, sound effects, voices, etc.
The way I did it is with texturing tricks and the tall foliage you see actually covers structural walls with sky texture on top of the walls. In effect, you can't see what you think you can see, because there are walls blocking the view.
It uses 100% custom textures, about half of which are animated, too. I tried to make it as close to the real Bloody Ridge as I could within the limitations of the engine. The "king of the hill" mode also fits the actual battle, in which 300 Americans had to hold the ridge against the Japanese to prevent them from capturing Henderson field. I even recreated the Henderson field direction sign somebody put on the top of the ridge as a joke.
