More sexy brushwork and textures. Simple as that. Just by looking at the screenshot, you know this map is purrrty. But, just as the old saying goes, don't judge a book by it's cover. All that really matters is gameplay, teamwork, and fun factors.
Visual aesthetics are just there to assist in enjoying the more essential parts of a map.
This map fails to provide those things, but rather is pure eye candy. Just like with the Valve maps, visuals aren't everything. You don't have a real base. The closest thing to be considered your base would be your shipyard, but it is so open and free to the enemy to be a base. Remember, in the way that the term base is used in this game, something has to be a defensive stronghold to be called a base.
