Assassin's Creed co-creator Patrice Désilets has finally reached an agreement over former employer Ubisoft, reclaiming the intellectual property 1666: Amsterdam in the process.

Désilets haw withdrawn his $400,000 lawsuit against the publisher in exchange for the rights to his open-world historical adventure title, which he once described as "the new Assassin's Creed."

1666: Amsterdam began life at Désilets' Montreal-based, THQ-operated studio, before moving to Ubisoft in 2013 when THQ became insolvent.

But Ubisoft quickly dismissed Désilets and "indefinitely suspended" production on the game, whose rights it owned.

Désilets is currently working on Ancestors: The Humankind Odyssey, an episodic third-person adventure game that has players "relive the greatest moments of mankind with a documentary twist."

It is unclear when or whether 1666: Amsterdam will undergo further development.
