Sometime during the week; the PC version of Bulletstorm was removed from the Steam Store, a cloud based gaming service from Valve, with no official explanation.
Many have speculated that it may be part of the potential shutdown of Games For Windows Live (GFWL). It has been rumored that the cloud based gaming service will be shutdown on July 1, 2014. However Microsoft has not made an official announcement.
The game is still available for purchase through Origin, a cloud based game service from EA, but GFWL is required. No announcement has been made regarding updates that would remove the digital rights management (DRM).
Omri Petitte of PC Gamer suspects that this will only be temporary until EA explores all possible options.
If the rumors are true, Bulletstorm would be one of a handful of games abandoning the service. Many game publishers have been abandoning GFWL in favor of Steam, Origin, or their own cloud based game service.
Bulletstorm is a first-person shooter that was released in 2011 for the PC, PlayStation 3, and Xbox 360.
