GD: FPS Multiplayer Map Concept: Eternity's Horizon!

Now that I've done all this FPS multiplayer research, it's time to come up with a map of my own!

The idea is, it's set on a futuristic monochromatic sci-fi rooftop. The player starts off in a bunker, the spawn point, on either end of the map and navigates the up and down motions of the buildings to find the perfect sniping spot. The player is fenced in by the height of the building-- falling off results in death. The level is set during evening, so spotlights can help guide the player around the level. There are elevators, which help in ascending quickly to the all-important high ground, but they can leave the player exposed compared to the relatively protected ramps. There are also other moving aspects leading to secret areas of the map where the player can pick up more ammo and health.
