Kill.Switch

As a relatively straightforward third-person shooter, the most distinguishing characteristic of Kill Switch is its cover system, a mechanic that has the player character taking cover behind objects and around corners in a manner similar to Namco's own Time Crisis series of light gun shooters as well as Koei's third-person shooter WinBack and Konami's stealth game Metal Gear Solid 2: Sons of Liberty.
