Im liking the photo of the exterior of the map. The teleporter hall looks a bit too long though...can this be shortened up a bit? Otherwise I think that battles will be too confined within that space.
The teleporter relay is on a 45 second spawn/ despwan timer. The hallway contains a soft killfield so the overuse of this hallway should not be an issue as generalaly speaking players will want to get in and out as soon as possible. This aswell as other features including weapon placements is explained in my video walkthrough of this map. However im having issues posting the youtube link with the upload.
