Deus Ex 3 (2004-2005 Ion Storm project)

Deus Ex 3 was a cancelled, third main title of the Deus Ex series developed at Ion Storm from 2004 to 2005 by Jordan Thomas. The project was one of two attempts by Ion Storm to develop a successor to Deus Ex: Invisible War, the other attempt being the concurrently developed Deus Ex: Insurrection. The project was cancelled when Eidos Interactive closed down Ion Storm in February 2005.

Story
Deus Ex 3 was planned to be prequel to the original Deus Ex. The protagonist is a biotech firm's failed experiment. Cast-off by his creators and starting on a literal scrapheap, he has no choice but to become a mercenary. The story would have a theme of revenge against the company that created the protagonist. Similar to the story concept in Deus Ex: Insurrection, the protagonist is the father of Paul and JC Denton.
