Breached is a map designed to play all core game types available at the moment. It supports up to 4 teams and 16 people. The maps real focus though is smaller team sizes around 4v4 and 2v2. Between the bases the map is symmetrical with pathways and weapon placement the same on either side of the map.

Setting:
The map is staged in a Forerunner containment facility that had a breach some time in its past which some poor UNSC scientist, engineers, and Sangheli body guards unfortunately discovered. The facility and the planet are over run with the Flood and the lighting and the atmosphere of the map reflect this. A green sky and particles of the plague float around the map help to immerse you in to this world. To help play on some nostalgia designs for the rooms in the map have come from popular Flood maps from past campaigns and the map has been made with Halo CE theme in mind.

Main room is from Halo: CE
Lift room is from Halo 2
Layout is inspired by Halo 3 missions.

Layout:
Red base (blue base mirror)
Teams and Team objectives (ie flag) spawn here. The teleporter featured in the back are both in red and blue base that lead to the mid room. Following that hall leads to...

Lift Room
this room has a shotgun and a stronghold location. The lift here leads to the incinerator cannon in the main room. along with the doors in the mid wall.

Mid
those doors lead out here into mid home of most of the fighting on this map and also...

Infected Irwin

Cannon
can be seen at the top middle of the picture. designed to be accessed by the lift or by skilled jumps as well as using the combat evolved tactic. the lower door leads to...

Long Hall
The lowest part on the map collects the most dust and flood effects as can be seen when players use this path to go between bases.

Outside
Alternatively you could use out side to go between bases and pick up an over shield or light rifle as well as taking one of the team strong holds.

Additionally thanks to everyone who helped with input and suggestions.
