Vin Diesel's Tigon Studios has said it sees upcoming Riddick title Assault on Dark Athena as an "episodic expansion", revealing that work on a true sequel to the 2004 Xbox classic is already underway.
Speaking to Eurogamer TV at the recent Atari Live event in London, Tigon head of production Ian Stevens said: "We've really tried to maintain that core experience [of the original] and embellish it for Assault on Dark Athena, which we see very much as an episodic expansion of Escape From Butcher Bay.
"We're not calling it a sequel; we've got a sequel in mind that's a couple of years out if you guys want it, and you like this and you tell us you want more."
Assault on Dark Athena is a new standalone adventure, and will release alongside an enhanced port of the Xbox original in the same package. Dark Athena, co-developed by Tigon and Swedish studio Starbreeze, clearly impressed at the Atari event, but Stevens insisted there were greater things to come.
"[The full sequel] is ambitious and that is definitely going to follow the precedent that we set with the first," he added. "But for now we've got a new story that we want to tell and a little bit of a single-player expansion on that original game."
The Chronicles of Riddick: Assault on Dark Athena is coming to PS3 and 360 next spring. You can see more on the game, and everything else on show at Atari Live, in the latest episode of The Eurogamer TV Show.
