Darkspore's gameplay engineer, Michael Arsers talks about the four player co-op gameplay mechanics and how they implemented Left 4 Dead's AI Director to create an experience that is always new for the players.

Darkspore is back on Steam, following its recent removal from the digital distribution service over service issues.

In the wake of the game's removal from Steam, developer Maxis has denied claims that Darkspore has been abandoned, instead announcing that a persistent play-denying issue has been fixed after months of gamer complaints.

GameZone writes, "Electronic Arts has reached out to us to clarify some confusion stemming from a game-breaking bug in Darkspore that resulted in players unable to log-in to the game and its eventual removal from the Steam store."
