German studio Yager Development's new title Spec Ops: The Line has been making waves throughout the games industry. At first glance, it seems like a generic military shooter... but it gets trippy. It's loosely based on Joseph Conrad's Heart of Darkness, and sends players a message different from the standard "shoot things, you're awesome, bro." In stark contrast to most military shooters on the market today, Spec Ops actually makes players (gasp!) feel bad about killing hundreds of people.
