is an action RPG set in the StarCraft universe on a moon of Tarsonis called Ender. You can choose one of four heroes, and then get right into your mission that will quickly show out to be of much more important than you would've dreamed of.
Gameplay
I could post pages about this. Even though this is "just" a map, and not a mod, the gameplay is extreamly far from what you normally see in StarCraft 2. 15.000 lines of galaxy-code, and various changes to the game-data is what makes up the unique gameplay and user-interface.
