Red Orchestra: Combined Arms is a tactical first-person shooter total conversion for Unreal Tournament 2004 and previously for Unreal Tournament 2003 originally developed by an independent mod team, set on the Eastern Front during World War II. It is notable for its emphasis on realism in comparison to other WW2-based FPSs. Unlike most FPSs, there is little on-screen information. There are no crosshairs in the middle of the screen, instead, the player must aim using simulated three-dimensional iron sights, compensating for the breathing of the character and natural sway from holding the gun. The player must also mentally keep track of ammo usage, unlike in games such as Counter-Strike which use an ammunition counter. Health status is not represented by points, but by a diagram of the player's body with reddened sections that show where he or she has been wounded. The bolt-action rifles in the game can often kill a player in one shot if rounds connect with any part of the torso or head. Semi-automatic rifles, such as the SVT-40 and Gewehr 43, are also capable of killing in one shot.
