Apollo is a CTF map I whipped together after messing around on Dust to Dust for a while. I'm not the kind of player who likes those non-inventory missions, but I love DtD's terrain. So I figured I'd mess with it. :)

Apollo takes place on a desert world, amidst a HUGE canyon/valley. Two similar bases face each other on ridges. Your generator towers are vulnerable in that they are a slight distance from the main tower/base, and they have no inventory stations. Protect your generators, or everything loses power, including the forcefields on the top of your base. When those forcefields drop, the enemy will have a very easy time dropping in on you.

Between the two bases are two capturable objectives, both have one of the two large turrets present on the map. One is situated in the valley, and another on a ridge near a long bridge crossing over the valley. Control of these two buildings is absolutely essential, as they can be very useful in downing that pesky flag runner. Not to mention they give you access to more inventory stations, etc. Hold these two objectives, and your only problem would be grabbing that flag...
