Quantum Theory Demo Coming to Xbox Live 'Later This Month'

Tecmo Koei says Xbox 360 users will have to wait a little longer before visiting the world of Quantum Theory.

Today the publisher revealed [via press release] a demo for its upcoming shooter will arrive on Xbox Live "later this month," but would not specify an exact date.


A demo for the game is currently available for the PlayStation 3. In the demo, players control a "hardened warrior" named Syd who has teamed up with the "mysterious" Filena to battle a black material that "infects anything it comes into contact with."

Quantum Theory launches on September 28 for the Xbox 360 and PlayStation 3.
