F.E.A.R. Combat is a standalone multiplayer component based on F.E.A.R. but released for free less than a year after the original game. F.E.A.R. already had full multiplayer options, but this component allows everyone to join the online battles, without needing to buy the game. It includes 22 multiplayer maps, 10 game modes, all the weapons and updates, and the ability to play user-generated content. You only need to apply for a free CD key.
