Wikipedia
Darkspore is a video game that borrowed creature editing technology from Spore. It was described as "a fast-paced, science fiction action role-playing game in which the player battled across alien worlds to save the galaxy from the mutated forces of Darkspore". In addition to the creature editor, the game features a unique squad-based mechanic, various multiplayer options, and a player versus player arena. The game was released in North America on April 26, 2011 for Microsoft Windows, and in Europe on April 28, 2011.
EA has removed the store page of Darkspore from Steam, meaning any attempt to purchase it through Steam cannot be made. The game was later relisted with EA saying that they would continue to support for the game. Those who have purchased it prior to the page's removal still have the game and could play it until the servers were shut down permanently on March 1, 2016. The game is currently unplayable due to its DRM scheme requiring a connection.
