John Konrad's surname is a reference to the author of Heart of Darkness, Joseph Conrad, a novel of which the game is loosely based on.

Yager, the developers of the Single Player of the game, have been outwardly spoken about their displeasure about the inclusion of multiplayer in the game, developed by an external team, being forced into the game by 2K Games.

Cory Davis, lead designer of the game, has gone so far as to say that it "sheds a negative light on all of the meaningful things we did in the single-player experience." He has also referred to the multiplayer as "another game rammed onto the disk like a cancerous growth", that is was "tacked on", "low-quality", "bullshit", "should not exist", and "tossed out the creative pillars of the product".

Walt Williams, the game's lead writer, personally believes that Martin Walker Spoiler:was killed in the helicopter crash during the sandstorm, and the game from there after is played out in his Purgatory.

The development team wanted to give the player the feeling that the game "was physically opposing you, not simply as a simulation, but also as the game itself." This includes things like the loading screens eventually ending up giving you irritating messages about how you've messed up and everything you've done wrong instead of gameplay tips.

The Main Menu is slightly altered everytime you finish a chapter. It goes from the basic upside-down American Flag, to a Sniper appearing, to the Sniper being dead, and buildings collapsing in the distance.

When talking about Spoiler:the white phosphorous scene, Walt Williams, the game's lead writer, stated that he wanted player to "be in the same emotional position as Walker." Spoiler:He stated the he "wanted the player to be where Walker was and be angry at [the developers], the people who made them do this".

During focus tests, several regular gamers were brought in to play large chunks of the game for feedback on the game. After this scene, several players paused the game and left the room to compose themselves. Williams wasn't expecting such an intense reaction to the imagery used during this scene.

Williams was met with some resistance to this scene from several members of the development team. Williams defended the scene, and eventually had the team agree with the purpose of the scene as being vital to the story's progression.

Walt Williams has stated that, at any time the game is making a standard transition, it will fade to black. Spoiler:Whenever Walker is hallucinating, or lying to himself in a delusional fashion, the transition will fade to white. This includes the game's epilogue, in which Walker believes that he is going home, fading to white. It is meant to be portraying that Walker is not going home, and he is just hallucinating it.
