Tournament Coastline is a very large map that is loaded with tiberium. Effective expansion is the name of the game. You start out with a sizable tiberium field and two expansion options. There is an expansion to your north/south, or you can go for the middle tiberium fields. There, you will be met by many garrisonable buildings. The tiberium fields here are huge, so massive Harvester spam is vital. There are also two Tiberium Spikes on this map that aren't really necessary to success, but can sway the tide of battle. This map has been known to support massive spam, and massive harassment.
