This map looks like your having a showdown in an enemy covie ship. The game play flow doesn't play very well like other maps I've seen from this user but it's not horrible. I don't like how my games here kept players sticking to the walls.
An extremely CQC map clearly designed with a one vs one match in mind, it certainly has the colour of a covenant ship but feels like it could have been decorated a little more, I also saw the banshees outside and knew what you were going for, however the effect didn't look right to me. Keep up the good work though, you clearly know how to make your maps look clean and symmetrical.
