Echo Delta

Revealed at Nintendo Spaceworld 2000, Echo Delta was developed by Clever Trick under Marigul Management. The game was a real-time strategy title where you controlled a submarine recovering parts of a sunken ship. You also had to mine energy from the ocean floor and deliver it to the "core" to upgrade your submarine. You would have to defend the core, and yourself, from enemy boats. After Spaceworld, the game was quietly cancelled.
