I designed a map based between an image I got from reading Halo: The Flood on the ring and the Maze Runner area.
It is supposed to be the pure feeling of being surrounded, outmatched, outgunned and your last hope is where you respawn. The map is in the night with a tree line basin around a single square base in the middle of an open field of long grass (about half the height of a Spartan) - the field is probably about two miles in diameter. The base is at the middle with two or three stationary weapons on the roof. When you enter the base, ammo is lying on a table to your left and a exploding barrel is to your right. Keep going forward and you would reach a ramp which goes down into a tunnel. The tunnel stretches under the field and forest to the bottom right corner of the map where the player will exit into a small shack. A rack of close quarters guns lies to your right. Outside is a Warthog or Ghost. Team 1 respawns cover the base in the middle of the field - NOT the shack, that is used for traps and means of escape when under heavy fire. At the bottom left tree line, a canyon cleft raised up from the ground holds a sniper rifle and the player can see across the map and into the windows of the base. Outside the base would be a couple of rocks - similar to Coagulation's ones which holds an MA5C Assault Rifle. To the top right of the map would be another cave entrance where further on it would be blocked, and inside it would hold the deadly red energy sword. Amongst the long grass would sit a SPNKr Rocket Launcher for taking out vehicles. Team 2 respawns match 2 or 3 per side of the forest, this means you respawn in the forest and can sneak along the grass to attack the prey hidden inside. Suppressed SMGs lay outside the base in the long grass and a Spartan Laser is hidden among the trees in the forest - a special for the player to find. If Team 1 players exit the base and go onto the field they are sitting ducks and can be blown away by a sniper sitting along the canyon cleft.
The map image design will come shortly as I do not know how to import images from your library and onto the topic - it only allows internet URLs for the image.
Nevertheless I have provided a detailed account of the map design and hope that you consider the designs.
