The latest issues of both EGM and Official Xbox Magazine collectively reveal that Midway has two new FPS games in the works for 2007.
Hour of Victory, thus far confirmed only for the Xbox 360, is a World War II FPS with a twist. Running on Unreal Engine 3 and under development at nFusion, the game focuses on three unique characters. The team's goal is to connect players with each hero, including class-specific objectives and Achievements exclusive to each hero. Environments will also be mostly destructible, as one would expect.
The other shooter is Blacksite: Area 51, confirmed for both Xbox 360 and PlayStation 3. Less is known about it, although obviously it's expected to be a FPS in the same vein as Area 51.
