Halo Reach Latest Beta Maps - All four maps were chosen in order to test a specific selection of gametypes and team sizes. Sword Base map and Powerhouse map cover the Slayer, Headhunter, end of the spectrum, Overlook map is perfect for the NT 1* ("Generator Defense") game type, and Boneyard map is a great landscape custom built for Invasion. All of the maps in the Beta are human themed, but several of the other maps have different themes that are really cool.
