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.

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".
