The Sum of All Fears is a 2002 tactical shooter video game which is developed by Red Storm Entertainment and published by Ubi Soft.

The game's first two missions take place sometime during the film, in which the FBI Hostage Rescue Team (HRT) works to save hostages in a Charleston, West Virginia television station, and shut down operations from a West Virginian militia calling themselves the "Mountain Men".

From the third mission on, John Clark recruits the team to work for the CIA and has the operatives work on seeking out and killing the conspirators behind an incident in Baltimore, Maryland, in which a nuclear bomb has been detonated during an American football game, killing a large number of people.

Instead, the player chooses from a small selection of pre-defined equipment packages for the entire team.

The player can also give a few rudimentary commands to the teammates, such as "wait here", "follow me", and "clear/grenade/flashbang the next room".
