An arena/king of the hill map for Team Fortress 2 set on a remote island with a lighthouse serving as both the central focal point and the middle capture point. It became an Interloper's spotlight from March through to July '09 and featured on the TF2 blog as a part of the 'Big King' map pack.
The map is available for download in two flavours: King of the Hill and Arena.
This map involved the usual creation of paper layouts, blockouts, playtesting and iterating, as well as creating the lighthouse mesh that forms as the focal point of the level.
