Formally Gael as a single playing area, Doubled, Then Triple Gael, You really won't notice the difference, but there are a lot of changes, the bots couldn't get out the pits so changed the meshes so they can, the pits are shallower than previous, the water has in and out splash sounds, all weapon bases are hidden, textures for floor now have metal sounds, all sections are zoned off for better fps, bot paths make the bots know where they are going, removed and added weapon bases and ammo, all sounds now mac friendly.
